In case you haven't heard by now, Project "I was only gonna clean the air filter" came to a sudden stop during our Dove Springs California ride (http://www.kxriders.com/forums/index.php/topic,11645.msg92808.html#msg92808 (http://www.kxriders.com/forums/index.php/topic,11645.msg92808.html#msg92808)) this past weekend. Absolutly nothing wrong with the way the motor was built......In this case it was all my error :oops:......
I began the heat cycles after the first build last year in early June so I got a full year of riding out of the motor.....I guar·an·tee that this motor would have gone much longer had I not brain farted so bad.
For those of you not familiar with my original build you can view it here.....http://www.kxriders.com/forums/index.php/topic,8890.msg69112.html#msg69112 (http://www.kxriders.com/forums/index.php/topic,8890.msg69112.html#msg69112)
Fortunatly for me my engine builder and half brother Motorrad was there.......bet you guys didn't know Dave and I were related :wink:.
So we pulled the motor right then and there so that "The Great Motorradini" could take it home with him and fix my shame......
This thread will be a combination of pictures and "one liners" from Motorrad with myself filling in the details........
And as far as the title goes, since the first build was started by my cleaning of the air filter I figured that to clean the air filter I would need to start at the motor this time...... :lol:
So everyone keep your eyes on this thread. I was asked if I wanted to keep this "hush, hush".......I am man enough to say that even though I am ashamed about this topic I am not embaressed.......My hope is that eveyone will learn through my experience of what can happen to even the best built motor........So pay attention, ask questions, enjoy and above all......LEARN MY LESSON INSTEAD OF YOUR OWN!!

I thought I should be the one to post up the first picture........My once beautiful Wossner revealed upon removal of the jug.....

ohhhh poor k5 hope motorrad gets her back up an running like new again for you.

OK so lesson #1......
I like my bikes looking good so I wash them after every ride.......not a good idea. I think I'm gonna stick to wipe down's with a wet rag.....My head studs and cylider studs looked brand new when the motor was assembled....Look at them now.

Try not to make a habit of hosing your machinery down on a regular basis and when you do make sure you start it up and get everything nice and warm.
Next item........the benifits of polishing your combustion chamber.....here is mine after 1 year of riding and this is what it looks like after wiping it off with a rag.....no cleaners of any sort were used.....only a rag.

"Thou shalt not wash bike so much as water creaps down stud threads and rusts them out. Warm bike up after washing to cook off excess water in hidden places" - ˭M˭ 19:19
I learned this the hard way years ago. I had the same exact bike as my dad, and he would wash his bike after every ride and I would not (not due to knowledge, due to lazyness). Pulled the heads off and mine looked new and his was a rust bucket. Here was how we dealt with it from then on out. Wash the bike every 3 rides or so, not every ride; only wash on a warm day, start in the morning so it can dry out all day; take a yard blower (more volume, less pressure than your air hose so you won't go blowing water into places you don't want to) and spend a few minutes getting rid of excess water; fire the bike up and cook all the remaining water out of it; and lastly, spray the whole bike (minus brakes, wheels, seat, etc.) with WD 40. The WD 40 will prevent rust, and keep things looking new.

So what's it looking like?
Plate and piston or worse?

Definitly piston......possible plate.........no other damage than that.........I shut her down just as I felt it starting to stick.

Alum is supposed to stay on the piston. :roll:

look at the flashpoint of your oil..... then know that K5's develop a 230-265+ deg trend on CHT's. (on the pipe)..

It will be interesting to see what my Sand bike looks like when I finally build the motor.
It has been washed after every ride and it's 14 years old..... :-o

This thread should be re-named "I was to worried about my airfilter, and forgot about my jetting"

which Maxima was he running??

What are you using to remove the aluminum?
-
What are you using to remove the aluminum?
swimming pool acid, and q-tips its cheap. eats the alum off VERY fast... and wont touch the nikasil.
put it on.. when it stops bubbling, the alum is gone,.
also very good for finding cracks HINT HINT...... (on newly plated, cyls also)

I could have sworn that I had a 170 in there......thats why I didn't even think to look at the jetting. No excuses......still very much my bad!!

actually it really doesnt attack the jug alum that much... but man does it eat melted piston.

OR
(http://jmjenterprises.ca/images/NPG.jpg)
The failure of the water as coolant, the failure of the Maxima burning off due to low flashpoint, the failure of the owner to have the proper jets.......all these factors led to this end result :x
But we're working on it to make it all better. :wink:
-
I bold and underlined the main problem for you! the others would have been fine with proper jetting. :roll: ideal... no.. fine. yes
fun looking at the msds for Super M
its up to 15% colman camp fuel..

is that Super M better than the Formula 2K that maxima sells?? thats what i run.. ima see if the local shop has that Motul oil and give it a shot..

Going to change your Piston window design.. I think the previous tuners design we are all using.. (no names needed)... may be too large, and LOW starving the boost ports to the transfers, as well as the floor ports...............
may go to a triangle shape.
-
A X-member told me that very same thing, that the window was too big...
I dismissed it out of hand but you have my attention...

I think I have a good idea of changing it. would involve re-location. idea came from some of BDI's secret squirel porting... insted of porting the added ports into the jug.... put them in the piston.. more to come.
stewarts piston port area 1.003sqin
my idea .72sq in and it would free and clear the boost ports...
so roughly 75% size
if you dig HARD... I commented on this design to said builder back when he first came up with it.. :wink: but like many.. I drank the Koolaid, and listened to him, instead of myself.
-
OOOHHHHHH!! I love being the guinea pig for cool ideas!!! :-D :-D :-D :-D :-D
-
I guess my theory is... why would one add a piston port right in the middle of a Rear boost port... causing the intake charge to go to the crank case, instead of a direct path to where it needs to go....
I hope people jump in on this discussion. Im not a one man band here.

I'll be getting my piston out tomorrow and putting it into my cylinder so I can visualize what your saying.

OOOHHHHHH!! I love being the guinea pig for cool ideas!!! :-D :-D :-D :-D :-D
have you ever thought about using "engine ice" in the coolant system?? i tryed it,as i had cooling problems with my kx360 big bore and it solved my problem... :-)
i take my jetting always on the safer side with a smart little bit to rich and i never blown up an engine in my live . actual k5 main jet 162 , but this is for mx only in my needs!
for long highsppeed distance like you did in the desert, i think 175 or bigger main!! in similar engines can be needed diferent jettings . caused of riders attitude,is the right gas in the tank?? which carb or exhaust is installed, which kind of air filter is used. i found out, that twin-air-filters have more airflow than stock-airfilters for example..
important: always take a look at the spark plug!!...
if high-octane-racefuel is used,needs complete different jetting than the 98 octane-super plus gas.
my ´97 kx250 has a 172 in it and was running perfekt in all conditions with dep-exhaust and twin-airfilter . the new owner was falling in love after first ride :-D
in my gasgas ec300 that i had a few yours ago, i ran 178 for mx and a 190 main was needed for street use and highspeed-offroad .
if the engine is jetted right, offers the fuel a little bit cooling extra . if its to lean jetted its heating up more and also to less lubrication,caused of the to small main jet !! and if you ignore to long the lean motorsound its heating up to much and....kaboom... .
and here is my cool guinea-pig ... yo :-D

thats not just a cool guinnie pig... thats a badass guinie pig...

my theory on how air will travel. (look at arrows in middle section.. and imagine if there was a big hole cut in the piston... how that would starve the rear boost port (which is at the top of the middle section), and the floor ports... making the air travel MUCH further than it has to to get to the comb chamber)

and my theory.. bring as much as possible flow to the engine for as much as possible performance, that is needed, but dont cut to much, to be safe that the cylinder dont crack up there... :wink:

I agree there is an improvement in running a window vs not. But I think we can improve on the current design.
to me , the current one is like slapping a U-turn in the transfer ports, making them go back to the crank case before they can then go to the comb chamber again..... kinda bass akwards

So any pics on what your thinking?

the windows seem to just Skirt (yes pun intended) the re-inforcing ribs in the piston (wiseco) will have to test the wosssener. so that is a good thing.. that was one thing I was worried about.

this design could also let ya cut the bottom of the intake skirt somthing like Yz250 skirts... for even more intake ............

Good day folks. I think you are on to something here Motorrad. I too think that the large lower port starves the boost ports, as the boost port pressure differential is higher than the huge gaping hole in the middle of the skirt creating a short circuit. By moving the piston port to the sides like that, the air will be diverted to the sides much better due to the pressure differential in the intake being moved outwards to the side triangle shaped ports, like you have cut. I believe this will in turn direct much more air to the side boost ports while the piston is still covering the main intake port.
I have a dyno at my work that I have full access to, anytime I need / want. I am already working on a test using two different window porting options to see what the relative results are. Perhaps I can help you guys out with some distinct numbers on these mods and the result (torque curve is what we are really interested in here). I will be plumbing in a couple pressure sensors so I can see the resulting waveforms with respect to the dyno run, to give me a closer idea of what the air is doing in there. I will be logging exhaust pressure, intake pressure at 2 different points, EGT, RPM and torque.
-
Alward25, I'll check what I have and get back to you if I need one.
-
awesome CB.. glad Im not out in left field here....
another thing I was thinking about.. on my triangle ports. is make it so they DONT open (unshroud) till RIGHT after the transfer ports uncover. in my mind, making the piston act more as a PLUNGER and getting more pressure and air moving through the transfers before it has a chance to suck through the windows keeping the charge that is in the crank case from pushing back out of the window and ending up around the reeds, as the piston compresses the new charge,, (gets the flow directoin moving in the right way first)
this will also make the boosters start sucking before the piston windows pull anything... once again. getting the flow moving in the right direction first...
thoughts?
-
you following all this USMC? this is your motor after all...

you following all this USMC? this is your motor after all...
I'm following as best I can.......I have to sit here and close my eyes to picture the flow characteristics that everyone is talking about but I'm good.......I'll ask if there are any gaps in my brain to fill. :wink:
I think sticking my piston might have initiated a new way of modding this piston and I am glad to have sacrificed my K5 engine "For Science"!!! :-D
-
once again. this is all just REALLY REALLY ROUGHed out stuff. dont judge radius's, exact shape, size etc etc etc..
here is what I was thinking from the yz250 pistons.
this bottom cut CLOSES just as the transfers open...... which should keep it from starving the lower floor port and the boosters...

This makes a lot of sense if the jug has the ports why not the piston...Looks good Mr M!!!
-
once again. this is all just REALLY REALLY ROUGHed out stuff. dont judge radius's, exact shape, size etc etc etc..
here is what I was thinking from the yz250 pistons.
this bottom cut CLOSES just as the transfers open...... which should keep it from starving the lower floor port and the boosters...

Interesting idea there with the lower piston skirt shaping there in the last 2 pictures. I think we want to be careful with that area, as to not decrease the pumping effect of the piston moving down. If there is an opening there when the pressure under the piston is greater than the intake, air will flow in reverse into the reed chamber. Your pictures are very informative, I like how the angle you cut into the piston is different than than the angle of the boost port. This gives a nice transition into the piston boost port, which will reduce negative turbulence as the piston moves upward sucking air into the case. That angle and depth may be good parameters to experiment with. Keep it up, I'm liking your ideas!
-
I 100% agree we need to be carefull in that area... I think as long as it closes the bottom before the transfers open up... we should be fine... ??? :?
heck.. would be better than that low window in the "S" pistons. that would be a problem just as you described.
-
How much closing is enough :?

for refferance.... here is a "S" piston in exactly the same location as the last to pictures above. (exactly when the transfers open) you can imagine how that would starve the rear boost port....... and as far as lower skirt cutting.. the one I showed cut, that closes as the transfers open.. has to have better pumping action than the "S" piston, that is WIDE OPEN .... YES NO? Im just going off my thoughts here... What ya think CB?

Just for clarification, are you we talking on the down stroke or up stroke?
I like the split boost design better than the large central boost port in the piston. this will help split the air up and direct it towards the boost ports, with minimal short circuiting. How cool would it be to add extra oil holes on the piston wrist pin boss directly behind these new ports haha.

So many projects.... so little time....

what does everyone think of..
1. not opening the piston window's till right AFTER the transfers open. (on down stroke)..
2. Closing the bottom of the piston cut right BEFORE the transfers open (on down stroke)
Playing some more.. I can get .839sqin of area (.419sqin per port) all without them opening untill the transfers are already open.. am I being a bonehead and missing somthing by having them open after the transfers?
-
Sounds like maximizing the pressure charge.
The sonic pulse from the pipe is supposed to be the end all but, I dont believe it. There's definite gain in lower crankcase volume & timing it to maximize it :evil:. I've also read that its not the size of the piston port... but thats not what she said :cry:
-
And, it looks really cool too 8-)
That being said I've been looking at the pics a lot since you posted them yesterday it sounds like the right approach.
I just don't see a downside to it, said the blind man..
-
okay,. keep in mind this is on stock hight jug. and dont judge the CRUDE work. just playing and testing at this point, and the dremel and fast cuts is the easyest way to do that right now. once figured out, angles etc will all be cut on the mill...
bottom skirt cut closes 2mm before the transfers open..
windows start to open 1.5mm after transfers open..... they arnt fully open untill BDC..
the tape line is to cover where I cut further down the piston to start... decided we dont need to go that far. ??

Here is BDC. note, They window doesnt go all the way to the bottom... in theory, to keep from starving the floor ports, and the booster ports.. (also need that hight, to keep them from opening before the transfers). hard to tell in the picture.. but when FULLY oepen at bdc. the bottom of the window is half way up the side boosters...

I like this cut much better, with the tape covering the bottom of the piston window to delay them a bit more. It may even be beneficial to taper the opening of them a little more too, to create a smoother air flow transition from the air flowing though just the floor and side ports, to the floor ports, boost ports and the piston windows. That way there isn't a sudden pressure change just as the air starts flowing through the other ports. I will try my skillz at paint and see if I can draw what I am talking about. Basically the tape would be oriented at a slight angle, angling down towards the center of the piston, creating a "V" shaped piston port at the bottom vs a square-ish style shape. Other than this one thing (which may be tiddlywinks...), I think you have done a great job at maximizing the port area while maintaining the air differential at transfer port opening (on the down stroke).

back on topic. been dead in here for a while. motor on my bench UN TOUCHED. went on vacation. best friends weddings. etc etc. life in general.
mostly. Todd Pinsonalult was off racing. now that he is free. the jug will go off to have him Knock out the kips dividers. as I dont have the tooling to do so. its the only way I think the jug can be saved without this problem showing up again.
On the piston. Ive moved on to thinking that 3 SMALL holes are in order. not sure if the skirt is strong enough for what Im thinking though... :|
2 like discussed earlyer, and on in the boost port, very high up compaired to the previous "port" renditions. to draw any charge that is trapped under the piston into the boost port.................
somthing like this.

Okay. back on subject.
lets chat piston some more.
Im thinking a top port like this, width of the rear boost.
and some skirt mods.
as I dont know if the skirts are tough enough for 3 holes.
will look into it more when there is a piston in my hand.

Once you start carving up your new/used piston it would be nice to see where a top port like this is with relation to the transfers. Does it extend the intake duration beyond when the transfers cover back up?

should be easy to see with my sweet half Jug that blaster sent me.
and the reason I want to add a port like that, is I believe the benefit of the S cut (big port in center) isnt more duration, but picking up trapped gass'es under the piston.
a higher up port liek the one I pictured would manage this, without messing with flow propertys of the flor and boost port.
as with those. we have same duration as a windowed piston... right............... dont think the skirt closes off those floor ports. Ill have to go look (memory isnt workign right now)
but Id like to add 2 more holes like the ones discussed earlyer, only smaller.
not sure if the pistons are stong enough for 3 holes...
-
Very nice, that will make this much easier to figure out. Are you thinking the skirt is too weak to run the two ports you were playing with a few months back?
-
Very nice, that will make this much easier to figure out. Are you thinking the skirt is too weak to run the two ports you were playing with a few months back?
im still playing with those.
But im thinking the benefit that was found in the previous window isnt due to more duration. but to releasing ALL those spent gasses under the piston into the boost port..
as we all know the K5 shrouds itself alot in the transfers at BDC. even with all MY skirt mods I already do.
hence the reason Im lookin at the VERY high up port. perhapse combine with the BOTTOM of skirt trimming (like the YZ250 pistons) I put up before may be the strongest and best way to go.
the bottom skrit cut will deff help those of us that have the jug jacked up to the moon like me.

kinda where im thinking of going.
not sure if pistons are strong enough.

Thanks motorrad... yeah I edited my post after yours and after thinking about it for a while this morning I can see the advantage over not overextending the rod length. Base gaskets can do wonders..

Rod length would make the opposite effect as what I do with base gaskets. your thinking is wrong. longer rod is like trimming the base of the jug down.
I want longer rod, to be able to fix the flaw we have discussed before with the exh port... as it is, there isnt enough room for longer skirt, without it hitting the crank.
-
Nice....
I don't think I explained it very well but essentually what I was thinking was fix the trasfer port issue and allow for fine adjustment with thicker or thinner base gasket and mr dremel..
At the races and have a hard time typing on my phone.. :oops:
My brother just crashed trail braking into turn one duri ng practice.
Everything is good but it was a little scary.

Okay. I wanted to run the top window port as wide as the widest part of the rear boost port.
mocked it up in my Half jug.
and. when the transfers JUST open. the top of that port will already be roughly halfway down the wide portion of the rear boost port.
sooooo.
I can either cut it as a upside down trapezoid, or make it square and the same width as the narrow portion of the rear boost port (same width as the previous "S" pistons)...
The pointed (stainless dental tool) marks where the top of the window port would be, when the ports open.

look at where mahle is puting their struts on modern designed pistons
I do like the middle high & tight like you have I think of the piston swinging around in there like swinging a bucket full of water in a circle, the most pressure is going to be in the very bottom. It also puts it opening above the reeds so they dont impede flow. I also vote rounded hole edges , nothing square or triangular as it focuses load. Just my 2-cent, from one who doesnt know

Theyre 4 stroke pistons for gas motors, but ... theyve moved the skirt support inward right to where your slicing the linear window.

Having the support there makes the piston strong enough you can make a 4.350 bore bbc piston weigh 740 grams which is sbc stock piston weight, point being theres gotta be alot of load going on in that area of the piston.

Just structural integrity was all I was looking at, as far as where you had the linear ports marked, the exact location modern pistons carry their load.

Ideas are brewing, thought bubbles are forming, theory's are cooking.........you will all be filled in as soon as things become more apparent. :wink:
-
been thinking on this piston window thing.
I believe the side port idea may effect aux port flow. as when the aux ports are needed they are a more direct route for the charge hiding in the intake area infront of the reeds.
I believe that the center "S" design will and DOES effect the floor and rear boost flow.
I believe the HIGH center port idea, will effect the rear boost port, even though it may clear the hiding charge under the piston????
Im thinking. that since the big K5 already has OVERSIZED transfer ports. we need all the squeeeze we can get.
Im now thinking that some Skirt modifications in the transfer port area like I already do is in order.
and some skirt modifications on the intake side. as like the transfer area, the radius's were made and designed for cast pistons to live. but since we are running FORGED pistons. we can get away with more... and thus, modify the bottom profile some.
thinking keeping the greatest ammount of area under (bottom profile) of the intake skirt open as long as we can till just before the transfers open up... is perhapse the way to go here...
so they will close JUST before the transfers open.. so we still have the nearly the same port duration as a window, with only a few degrees of closure, before the aux and boost ports pick it back up. (floor ports still cause it to be full duration open anyways) causing the piston to be a big plunger.... helping to shove the LAZY intake charge through those over sized ports....
thoughts??
warning. I didnt proof read this. just typed it............... :roll:
keep in mind. I build power for DESERT PEOPLE. not drags, or hill climbs so windows may work better for those "other" types.

are we talking skirt mods only with NO window?
-
are we talking skirt mods only with NO window?
correct.
just happened to have a windowed piston to color on...
-
The window is 2hp in the middle of the powerband right? so thats great for varied throttle desert right?
I really think you have some great theory with finding the right "pulse" with the piston window , it really seems you need to make each varied design get a chassis dyno & play "Lets change the piston game". Even the long side slit idea "looked" good & it might be awesome for 1 or 2 top speed runs & swap in another so it doesnt come apart.
Id still bet the higher the hole the better but its just an idea
-
are we talking skirt mods only with NO window?
correct.
just happened to have a windowed piston to color on...
I like the idea......looking at everything I do agree that having a huge hole in the piston will cause intake charges to follow the path of least resistance causing a starvation of all the other ports......From what I've read in the past, having the window aided in additional lubrication to the wrist pin.....is this correct and if so is there the possibility of oil holes being added to certain areas???
-
The window is 2hp in the middle of the powerband right?
Based on what fact.
a guy that screwed all of us said so?
that and we never saw a dyno for it. atleast I didnt.
just sayin.

If this is figure is correct, I can say this.......its a K5, is 2 HP going to break my heart?.......If so I'm sure that 2 HP can be found somewhere else. It would be nice to have a dyno, KX500, multiple pistons with different cuts, and a Motorrad all in the same place for a few days to put an end to this debate but these conditions are hard to come by.

Come on Stewie's "Gospel". http://www.youtube.com/watch?v=VAQz_g3qTO4
Hence the need of the dyno
-
and not saying "S" was wrong. or right... so lets assume its a good 2HP
many I have chatted with agreed that if there was to be a window.. to move it up, and make it smaller. myself included.
Im just saying. if the window was good for 2hp. (theory)... was it because of added intake duration (360deg)? venting the trapped gass's? or evil elf magic :-o ??
BUT.
what if another method was better?
Im thinking that with the window. you get a good initial "squeeze" on the charge. when the transfers first open, you get a rush, that is then short circiuted by the window. since it all trys to equilize due to the sort of short circiut the window and rear boost port cause. possibly... in theory remember. causing the second half (1/3 or whatever) portion of the charge to get lazy...
NOW..
with the skirt trimmed.
you still have Nearly the same 360 port duration, since the second the piston closes the intake, the transfers open up, causing the AUX ports and rear boost to take over the "360" effect the window had. then the piston has the chance to COMPRESS the crapola out of the charge, through the entire cycle, as it cant escape from the window into the boost port., causing it to keep the velocity up in the transfers (oversized remember), through the ntire cycle........ the only issue here is trapped gass's, and reverse flow, short circiut from the floor ports..? But the floor ports are fairly small, vs the transfers, so the charge should stick to the transfer route, and actually pull from the floor??

I always though the window looked to big in a stressed area off piston,
triming the skirt [like the cr500 piston ] could also make the piston prone to cracking
The kx already has 360 intake duration in the rear tranfers and the three extra rear inlet ports direct to crankcase

So the intake bridges are the issue how will a power jet help. I've installed them on Harley's and as I understand it they just provide more jetting options so you can jet a bike perfect at full throttle and still run well at no throttle.

I would say that for now we should leave the window out........you can always yank the top end and cut in a window if we discover its needed but you can't "un-cut" a window if you decided its not needed.

Not a bad price for a rolling road!!!
I work as an Electrical Engineer for an EFI controller and Dynamometer manufacturing company. I have many Dynamometers at my disposal and can do what ever tests you guys want to see!!! If anyone is interested send me a PM. I'm even open to weekend visitors!
Our Dynamometer, called the "Axis Dynamometer", is much different than every other Dynamometer out there! It simulates a REAL WORLD load on the bike, vs. the existing dynamometers on the market that require you set up different load profiles using an "Eddy Current Retarder" to get close to real world engine loading. Our Dynamometer uses air turbines to generate the load vs. speed characteristic that other Dynamometers are missing. We can also adjust the steady state load to the engine to adding or removing inertial plates (to simulate a heavier or lighter rider) so we can see the effects of a 100lb boy riding vs a 300lb manly man! :-D

Those are just thoughts and theory's for right now though. In the end I will trust the final decision from he who is controlled by the power of the.............

I ride about 75 to 100 hours of engine time a year, and have owned KX500s for at least 6 maybe 8 years out of 25 or so of riding. Have had windowed piston and stock. Different carbs and reeds, spacer, etc. Currently riding on a stock top end. What I have found out is that when it comes to this bike it is very tolerant of just about anything, and puts out good power with or without the window (and other mods) and with crappy or perfect jetting. Have had buddies with so much spooge coming out the back end it wasn't funny. Some setup the carb perfectly. We all climb the same hills, haul on the same sandwashes, and just generally have fun. Bikes can go 3, 4 hundred hours on top ends (with maintenance and good oil) and just don't care unless you go too lean.
Most important thing is to do the maintenance and if you are picky jet it perfect. If you want to put in a window fine, want to do the carb spacer or different reeds, fine. In the end all that may help some, but again the most important things you can do is the maintenance and JET the bike RIGHT.
One more thing, the KX500 is the most tolerant bike I have ever know when it comes to lean jetting. It won't complain much and will run a long time lean before it goes. Only lost one top end in hundreds of hour of engine time and it was my fault on the main. If you ride somewhere where you can ring the bike out in 5th for many seconds at a time (I do) go up one or two on the main. Only Danny Hamel could tell the difference in power and worse case you change the packing in your muffler more. If you never ring the bike out much (for many seconds at a time) you can live with the top end more lean.
From what I can tell Kawasaki pretty much got this engine right...hard to find anything that could run the 1000 so many times with (from what I know anyways) are somewhat stock motors? Bottom line Oscar if you ran it with the stock top end and went up on the main one or two sizes you could run that motor hard for years and probably never notice the difference with or without the mods...IMHO.
-
There wasn't a single part untouched in the Baja bikes. No joke. Even custom cases. Tranny shafts. Etc. To make em live
-
Oscar what type of riding do you do? How would the window be a negative?
-
I can find comfort in the fact that in all the threads I have going on this site people have been able to discuss and share their thoughts and findings with their own machinery. One of things that I love about this site is the drama and ego free discussions. I'm positive that if I had kept a closer eye on my main jet my "Motorrad" built engine would have lasted countless hours of riding. In the last few months I've ridden everything from Japanese to European, 4stroke, 2stroke, 300cc to 650cc.........and in all that riding I can say this.......My KX500 even when I ran it rich made more power than any of those machines anywhere else in the rpm range. I'm no longer going to worry about perfect jetting.....I will jet slightly fat on the top end and ride it forever. :wink:
-
Oscar what type of riding do you do? How would the window be a negative?
I ride everything from desert to single track........I won't be making the final decision on the window. I'll leave that to Motorrad. His theory's are much more solid than my own. Any questions on my engine build should be directed in his direction. If you read a few pages back on this thread there has been discussion on window and windowless design and different styles of window. Either way I'm sure I'll be happy with the final product. :-)

I've rode my k5's since 2000.
I have played around with jetting chasing numbers for elevation and temp.
Yes, a bad jetted k5 will still pull away from just about any stock bike out there.
But one that is correctly jetted will rip the guts out and stomp all over them. 8-)
In all fairness I couldn't tell a lot of difference on the dirt or sand.
But when I started playing with the street tard jetting became a bit more obvious.

Difference is this......on dirt you have wheel spin which allows the engine to spool up with less effort......kinda like slipping a clutch...........but with pavement you have no wheel spin which makes the engine work harder to get up to speed......that's why jetting is much more obvious on the road.

+1

Digitron. Takes the guess work out
-
Motorrad I would guess that Kawasaki modded the engines for the 1000...polishing, porting. etc. But did they use forged pistons that were windowed? Just curious how far away from stock they got on the top end components?
Sandblaster perfect jetting makes a difference on the street...especially for a 2-stroke. Nothing like the 500 doing the "surge thing" as you come up on a tight corner after a high speed run while letting off the throttle...can you say "Hi" to the guard rail?
USMC 500...no matter what you end up doing I think this will be the last top end you will need for a long while... :-D
-
You know what the really cool thing about getting the jetting dialed in on the street?
Then you use the same jetting for your dirt, desert, or sand machine (as long as you are at the same altitude) and you feel what your bike was really meant to do off road.
I completely agree with you Mohave, If your concerned about eating a guard rail on the street because your bike is jetted nicely and you don't know how to compensate for the surge effect then it's probably best to stay with what your comfortable with and stay off the street or run your bike rich.
I for one wouldn't want to see anyone get hurt or damage their bike over anything I have suggested or otherwise.
Life is too precious and short for the trivial.
-
Are you saying a properly jetted bike will still surge?
-
Custom cases with larger main bearings (among other things). larger main shafts in tranny. Modded cranks, rods, pistons, heads.... etc etc etc

Nothing?
the upper intake holes are open to the boost port for a timed cycle, so they will releave some of the under piston charge and pressure. not much. but those holes are bigger than the others for that reason. (not seen in picture)

Sweet! run it and let us know if it whistles :-o

Very nice.
I hope this works well.
I have to get another engine done before spring....

85.97mm bore
.017" ring end gap
.040" custom base gasket

Isn't that ring end gap a little large?
-
Isn't that ring end gap a little large?
larger than Id like.
but your hard pressed to get any tighter with off the shelf rings and pistons. hell last JunkCO (wiseco) piston I had around, specd in at .025"
the only way I have been able to get tighter than .017 is custom hand fit rings. which only my bike see;s as its alot of work
-
now someone ask the garage gremlin where he put the base and head nuts.
-
in a cut off top coke can. good place gremlin.
.0140" in the hole deck hight.
which will bump the compression up a smidge to 13:1 even.
and drop the squish clearance down to around .044"
all "ISH" based off the old numbers on the motor.

Next weekend will be the official "light off" ceremony at "Casa de Motorrad".........I will film the event and post it up for everyone to see. :-D

A big thanks to Motorrad, Sandblaster and Alward.......Let me know if you ever need to hide a body...hahahaha.
took GoPro footage of the ride and I'll post it soon.

Glad to hear its running again. You've built a motor, blew it up, and rebuilt it before i finished mine. What do you attribute the extra grunt to?

Not too sure exactly but I'm sure Motorrad will chime in sometime.....I think compression was bumped up a bit and there were a couple things done different to the piston than the previous design..... :-D

yes he runs a MZB ignition. with the optional lighter flywheel.
Running 2 .020" cometic base gaskets for a total of .040" not to raise port time (by product) but because his stacking tolerances needed it for piston to head clearance reasons. (more info on that in his first motor build thread).
Head info is as follows.
13:1 ish compression (un corrected). 42cc head volume. .010 head gasket. .0145" piston in hole
Squish clearance: .044"
88mm width
.48mm head step
4deg cut for 4.89mm to 15deg for 9.66mm
total squish width (measured straight instead of cuts) 14mm from edge till you hit bowl edge
Motor will be run on 25% 100LL avgas and rest 91octane pump fuel. ONLY because our California fuel SUCKS. the bike would tolerate just 91 pump fuel (except for maby in the dunes)

I would like to know the timing of all the holes you made in the piston.
It would be really appreciated.

So did you put on one of Alex's ignitions? Did you use a stock base gasket or change the jug height? I'm assuming the squish was modified. Will you be running on race gas? What's the deck height?
Did I answer your question good enough?

Snow flake?
WHAT?

Somehow I knew that was coming :roll:
Can you give us the formula for each stage of the calculations?

Yes Sir. Is that motor running an 88mm piston?

well for the intake timing. It would change if your running a wiseco vs wossener vs.........
The wossener "step" in thickness is a nice machined cut, where the wiseco is a stamped curve. making it so you cant run the holes in the same location as eachother. (the highest ones on the intake side) that, I have acting as timed bleede holes to the boost port, to get some of the gasses out from under the piston, in a timed fassion.
I have the holes on the wossener , right up against the first step,
the intake skirt is then trimmed,
math is done, so the holes are even the rest of the way down.
Exh side. well that one is a much more involved story. timed short circiut I have in it and all to help fill the ignition side case better.

Excellent.
I need to get my bottom end assembled, figure out my port timing that I want to run, and then deal with the snow flake factor..
Thanks Motorrad..

Hows the engine running?

from what I hear his ass is running from bad tacos instead of his motor

not more food poisoning.........bike is running great. I SHOULD have something special to report after this weekend. :-D
-
Been quiet over there. Clean the filter yet?
-
Bike runs great.....looks great......is great. Ditched that stupid ASV shorty clutch lever and put on the stock clutch lever and perch off my CR.....BUTTER!! I now await a few projects that Motorrad is working on to possibly adapt to my own. One thing I have been looking at is one of these.......

I'd like to be able to keep an eye on my EGT's without paying big $$$ for a Digatron......
After driving big rigs and being in aviation I'm used to being able to know what my equipment is doing and having displays like this......

No. Someone just hopes he doesn't blow up a motor I still own. :lol:
and my piston is alot of freeking work.
and sponge bob is real.

I've been looking at that Sponge Bob animation for a while and I can't find anything I'm missing :?
I know your pics always have hidden meanings, obvious blunders, and intentionally useless information but I'm just not seeing it :roll:

No updates......haven't been on the bike much.....My supervisor just accepted a job in Texas and I am the "fill in" supervisor, possibly the permanent supervisor :-D......been lots of long work days lately. :|
-
Time to clean the air filter again yet?
-
Some ones gone AWOL. Time for a court martial?

With all the personal stuff I got going on I haven't had much opportunity to ride but the little bit that I have I can sure tell you that this motor is definitely a lot more fun than it was before.....and it was a blast the way it was before!!!

Your alive??!!

DUDE!!!!

DUDE!!!!
I'm here......still alive......just dealing with some of life's curve balls.

No doubt.... Sometimes life presents us with interesting and unique challenges.
Just don't forget who your friends are :-D

Yeah man you will get through it!!! Us men are resilient creatures! :lol:
WELCOME HOME DUDE!!!

Escort Services make a wonderful difference in how much those "curve balls" curve!
Once everything gets squared away, I think it's safe to say a lot of us are looking forward to the next Chapter, or Novel, of "Clean The Filter" build!! :mrgreen:

heheee...it's probably a good thing we're not close by...we'd probably end up as cell mates!!
my mind just refuses to leave adolescence behind, and grow up....
I'll be that dirty old man in his 80's standing outside an aerobics studio or something similar, with my hands in my pockets....but, only I'll know that the pockets will be cut out!! :evil: :-P

So is anyone running a full window piston in their kx500?
