Title: My 1999 KX250 Build
Post by: mjowen on March 05, 2018, 02:49:14 PM
Hey, everyone -

Figured I'd post to keep track of the progress i make on this.

I've been looking for a project bike to give me something to do and decided i'd get into the dirt world. Was searching craigslist on saturday and stumbled upon a 1999 KX250 a couple hours north of me. The motor was locked and the guy was selling as is. Ended up making an offer and after a little back and forth we agreed on 500 bucks for it. So, i finished my mimosa and headed up to Cheyenne to pick it up.

Again, this is my first jump into the dirt world and my first 2-stroke ever. Not quite sure what i'm getting myself in to but we'll see how it goes haha.

The bike is in alright shape overall but definitely needs some mechanical work and some TLC.

The plan for the bike is as follows:
- Top and bottom end rebuild
- All new fluids, plug, filter, etc
- New plastics
- New graphics
- New chain kit
- Possibly powdercoat the frame (we'll see how frisky i'm feeling); prior owner painted it black and it's of course chipping now. Might just sand it and repaint it, not sure.
- New front and rear tires
- General cleaning

Heres a quick pic after unloading it and putting it in the garage:
(https://i.imgur.com/Sf7xKeFl.jpg)

As of tonight, i've accomplished the following (which i've hopefully done right):
- removed the seat and plastics
- removed the tank
- removed the exhaust
- drained the coolant and oil
- removed the radiators
- removed the carb (although i left it mostly connected)
- removed the top end

Someone obviously started this project and didn't do anything with it. First off, there was no gasket on the top of the head. Second, once i got the top end off i found the piston to simply be sitting inside the cylinder, on top of the connecting rod. Needle bearing was inside the piston as well. I've got a list going of the parts and pieces i'll need to buy but i'm sure i'm going to be needing everyone's help since this is my first attempt haha...i've noticed a couple things such as a random hose missing on the carb, bolts missing, exhaust basically held on with the springs and two bolts, few other things; but i'll figure those oddities out later.

Here's how she sits at the moment:

The tear down has seemed to go just fine so far and i dont believe i've done anything wrong...at least i hope i havent haha.

Not quite sure what i'm going to do next...of course i still need to get the bottom end torn down but i still need to do a bit more reading up on this and then re-watch how to put everything back together.

If anyone is around Denver and wants to help a noob, lemme know haha

Not a bad buy for $500.
Before ya go any further, you should get yourself a Service Manual...if you haven't already.  :mrgreen:

Post by: mjowen on March 06, 2018, 12:55:14 PM
Yep! I actually downloaded a PDF manual the day I brought it home haha

Did a little more work on it tonight:
(https://i.imgur.com/mhkRtMKl.jpg)

Got the remaining plastics removed (minus the fork guards, will do those when i remove the fork and do the fork seals)
Chain removed
And removed the bottom end

I'm going to be going to a guys place next week saturday to split the case and figure the rest out (he's familiar with this, i'm going to learn lol)

Tomorrow or maybe next week:
- remove the sub frame
- remove the swingarm
- remove shock
- remove fork

Then i'll get some pics of the wiring so i know where it all goes and will remove that...then i'll have the powdercoat done.

Parts list is mostly together pending anything crazy with the bottom end. Hoping to have the parts ordered within a couple/few weeks and will then start putting it back together.

If you have not purchased your piston yet, consider getting a Wossner.  Several very knowledgeable engine builders on this site swear by them. I put one in my 500 conversion, and I was very impressed with the quality and finish. They also make very nice rods if you are going to rebuild the bottom end. On this site, Sandblaster or alward25 are Wossner dealers if you want to buy from someone you can trust.

I greatly appreciate the suggestion, man. I havent purchased any of the parts for the rebuild yet...i figured i'd get the full tear down done, write a parts list knowing what i need, research them, and then pull the trigger on parts.

I'll be sure to look into those wossner pins...i'll be doing the bottom end rebuild as well so will look at them, too!

Alrighty...made a bit more progress as of tonight:

(https://i.imgur.com/VdaH4fTl.jpg)

everything is mostly stripped. Still need to remove the pegs, those little plastic cover thingys on the frame, and remove the lower triple clamp (once i research how lol)

I'm in no rush though, things are just going to sit until next week when I split the bottom end and figure out whats going on inside there...then will order parts and start the rebuild.

After removing the shock and forks today i'll definitely be adding a shock service and fork rebuild to the list.

Nice! I was able to quickly browse it today at work (about to go home) and will look at that in more detail later...gives me some hope for this one haha


There are some good "how to" vids on rebuilding your suspension on Youtube.

Yeah, i've read a few of them...havent looked into the forks much but did look at the shock. What is deterring me a bit is needing some special tools to get it done - i'll see if there is anyone near me that can help out as well.

I'll be going to a connections place on Friday to split the case to figure out the motor issue...then will order parts and start that rebuild.

Alrighty...found out some great news with the motor today while doing the strip and most of the rebuild!!!

All that was wrong with the bottom end was piston skirt particles which prevented it from turning. Rod still in spec, and clutch basket fingers not too bad. Trans and everything else in real good shape. One of the KIPS valve shafts has some damage so ordered a new one and will replace that once the cylinder is back. Someone had already put a hot rods crank in at one point as well which was nice!

I apologize for the crappy pics...my camera was dead so i just took some snap pics and took some screenshots. Have to wait for a few parts to come in next week in order to finish up the motor...hoping to have it all done and top end done within a week and a half or so (depends on when parts get here).

(https://i.imgur.com/2Eu1fdGl.png)

(https://i.imgur.com/PRcEp6Jl.png)

(https://i.imgur.com/75QUBWll.png)

Ordered as of today:

New piston kit
New water pump impeller
Bottom end gaskets
front and rear brake pads
new air filter
new piston sleeve (being done locally which is nice)
Couple oem parts needed such as some bolts and the kips valve shaft
new plug
carb rebuild kit

Next up:

frame power coated
rebuild the rear shock
rebuild the forks
order the chain kit
few more oem things such as exhaust coupler and bolts
new front and rear tire

then i'll start rebuilding and will decide on plastics and graphics :)
Title: Re: My 1999 KX250 Build
Post by: mjowen on March 21, 2018, 09:05:52 AM
Well - no pics at the moment but i'll get them up eventually...

motor is done. Just have to go get the top end from the shop which i had resleeved.

Shock has been dropped off to have a rebuild done (full rebuild for 130 including parts)

Frame is at the powder coater which i'll get back eventually...

Next up:
- fork rebuild with bushings, seals, fluid
- order the rest of the parts
- start putting her back together!
Title: Re: My 1999 KX250 Build
Post by: mjowen on June 11, 2018, 01:21:59 PM
Sorry for the late post...

took quite a while to get that frame back for some reason. Oh well...it's back and now i can continue!

Here is how the frame turned out:
(https://i.imgur.com/6zfg3VBl.jpg)

I've got the front and rear tires mounted
new radiators and hoses in the garage
new filter in the garage
all new oem bolts
shock has been rebuilt
chain and sprocket kit in the garage

Now just waiting for the forks to be done...one of the forks was missing a valve assembly so ordered that today and will rebuild the forks. I also have a few new bearings ordered which i'm waiting for (front and rear wheel bearings as well as the steering stem bearings)

Next up:
- start putting everything back together
- rebuild the carb or at least clean it
- fix the gas tank mounts (one spins free and one is missing entirely)
- order the new plastics
- new graphics kit
Title: Re: My 1999 KX250 Build
Post by: mjowen on June 13, 2018, 04:01:30 AM
Just a quick update...

- carb cleaning done
- fork assembly ordered: apparently they're now discontinued so had to track one down rather than ordering it through the shop

I'll post a quick photo later tonight of the motor and rims/tires.

I've also shot a message out to a shop to get the swingarm coated - its really not in great shape as you can see in prior photos. So, we'll see what happens there!

Post by: mjowen on June 13, 2018, 06:08:46 AM
haha, i will for sure...i've been slacking in the pic department lately. I got a new puppy about 6 weeks ago and he's been taking up quite a bit of my time as well!

Here are the issues i've run into so far:
- most of the bolts are all different sizes and head types so had to get all new
- missing some clamps here and there but wont know exactly until i start the rebuild
- missing a fork valve assembly on one of the fork tubes
- rear wheel spokes were shot so needed a new spoke kit on the rim before the tire could be installed
- wheel bearings were shot both front and rear as well as the swingarm bearings
- gas tank mounts for the plastics are stripped: one is missing entirely and one has a broken bolt inside and spins freely - will fix that as well
- sight glass is cracked but ordered a new one and will replace when i do a fluid change next

anticipated issues coming up:
- i ordered the valve assembly from rockymountainatvmc, they said one was in stock but i have a feeling they're going to tell me they dont have it as its been discontinued so will have to track one down
- i expect to have to replace the brake lines as everything else has been shot
- i believe the pipe that was on the bike is the wrong one as there were some fitment issues. I havent looked into it but will tonight or tomorrow: might sell the current and pick up a stocker if so.
- i expect to have some issues with the wiring and kill switch: it looks alllllll spliced up and crappy. so, we'll see.

I think that's it for now but i'm sure i'm missing something lol. Lots of issues here and there but overall has been a smooth...

I'll post some pics tonight or tomorrow...need to pick up the rims either today or tomorrow :)
Title: Re: My 1999 KX250 Build
Post by: mjowen on June 14, 2018, 08:29:22 AM
Figured i'd post a few pics! My last post will be kind of a start to finish one as a recap...

Picked up the rims today with new tires, tubes, and spokes. Also got the swingarm dropped off for powder coat which i'll get back in a week or so.

Motor...all together (minus a couple bolts which i had to order due to them being wrong when i took it apart)

(https://i.imgur.com/ndHlieKl.jpg)

Rims/tires...new front and rear tires, new HD tubes, and new rear spokes

(https://i.imgur.com/wvu27tKl.jpg)

Hoping to have the forks back within 2 weeks (depends on the assembly)
Hoping to have the swingarm back within a week so i can put the new bearings in
Then will start the rebuild!
Title: Re: My 1999 KX250 Build
Post by: mjowen on August 14, 2018, 08:50:50 AM
well...my bad for the long absence...it took forever to get the swingarm back due to a personal issue the powdercoater had. oh well. Just got it back a few days ago.

Replaced the front and rear wheel bearings today
Forks are done and back
Shock is back (if i havent said that already)

Here are a couple pics of the frame and swingarm together. Frame is done in a 70% gloss gunmetal gray and the swingarm is done in a 50% gloss black.

I'll be doing the swingarm bearings tonight then hopefully going to begin putting things together tomorrow night. I have a best friends wedding which is taking up Thurs/Fri/Sat/Sun so i'm hoping to get the majority of it finished by sunday afternoon or monday since i took monday off.

Will post more pics as i start putting it together :)

That's going to be a very cool color combo.  Have you tried holding the plastic up to it to see how it looks with the green?  What color are you doing the subframe in?

Did the subframe in the same gunmetal gray...havent held the plastics up yet because i havent gotten them. I dont think i'm going to go with the white/green plastics and am going to go with black. That way if i decide to do a green theme i can go with the graphics and always change. We'll see how it goes...kinda winging it at the moment haha. An ex gf of mine does the motox graphics for one of the shops close to me so she's going to do them for me at cost...thinking i'll send her a pic of the bike once its together and see what kind of ideas she has.

Just finished up the swingarm bearings...had some free time so got those done. Now might get the gas tank repair done - need to put some new inserts in as they're stripped out. I have all the parts already so going to hope the fix will solve the issue otherwise i'll just pick up a tank at some point.

End is somewhat in sight!!!
Title: Re: My 1999 KX250 Build
Post by: mjowen on August 16, 2018, 04:09:39 AM
Got the tank done last night...i may end up sanding the plastic bond a little but will decide that after i mount the plastics and check fitment.

One side of the tank was missing the insert entirely and the other side was stripped out and also had a bolt broken off inside it. I removed the stripped side and drilled a half inch mount. I roughed up the surface so the bond would hopefully adhere a bit better. I used my heat gun and softened the plastic then pressed a tee nut into the plastic, let it cool, then removed it. I used alcohol and cleaned up the surface then used plastic bond and pressed the tee nut into the hole. I used a bolt with some grease on the threads and end so the plastic bond wouldnt get into the tee nut. Once it dried a little i simply removed the bolt and let it finish drying.

Will it work? No idea...worst case scenario is it works for a brief time and then i end up getting a new tank down the road. Best case is that it works and only cost like 5 bucks.

Finally got around to starting the rebuild...

got the frame/subframe/shock/motor done last night.

Planning to get a bit more done tonight so we'll see what happens! Supposed to meet a friend for drinks first which is why i'm only "planning" to get more done and it isnt guaranteed lol

I have most of the swingarm completed as well but when i was putting it together i realized i was missing a few oem parts so i ordered those in which should be here by end of week. Then i'll get the rear done. Also have fork guards and plastics ordered in which should be here at the same time.

So far completed:
- frame
- subframe
- shock mounted
- motor mounted
- radiators mounted
- hoses in
- harness routed
- front and rear wheel bearings done
- swingarm bearings done
- steering bearings done
- triple clamp mounted
- forks mounted
- front wheel mounted
- new front brake pads installed
- new grips done

What i dont have pictured is that i installed the carb and routed the throttle and cable

Next up:
- finish up the swingarm
- install the rear wheel
- install new rear brake pads
- install the gas tank
- install plastics
- install seat
- install exhaust
- mount the skid
- install new pegs (havent ordered them yet)

should be about it! Hoping to have it completed within a week or so - just depends on when i get the remainder of the parts.

Post by: mjowen on September 05, 2018, 09:42:05 AM
I've decided that i'll replace the carb vent hoses while i'm doing everything else...

so, going to pick up 10' tomorrow and will get that done as well...

I've got one shipment of some parts coming in tomorrow...another coming in monday...and the plastics in on tuesday. We'll see what happens for the rest!

I cant remember exactly how the harness routes and where two of the ground connections are and am also not positive on how the vent hoses are routed as they were all over the place when i got the bike - so, i'll read up on that tonight in the service manual and give it a shot tomorrow!

Got the new vent hoses done on the carb tonight...going to read up on the harness routing as well as the other cables tonight and will do those tomorrow (I did route the clutch cable tonight).

Ran into another issue though...i remembered the exhaust fitting weird when I took the bike apart so I did a quick test fit and it's not even close. Looked up the part number and the pipe that I have is for a 91-94 kx250.

Will clean it up and post it for sale on eBay for recover a little money (hopefully) and have ordered a new pipe for my bike as of tonight...

Hoping to have this completed by Friday next week!

Post by: mjowen on September 11, 2018, 11:07:38 AM
Got a bit more done on the bike last Friday but i had to take off to Chicago so i wasnt able to post any pics before i left...

- upper and lower fork guards on (havent mounted the guides yet)
- new c clip on the front sprocket
- new sprocket guide
- new clips for the vent hoses
- swingarm mounted
- rear tire mounted
- new rear pads installed
- new chain installed
- new pegs

Very impressed with how perfect the pegs matched my frame color choice - wasnt planned at all. I had the frame powder coated and then ordered the pegs months later.

My new plastics came in yesterday while i was out of town...new exhaust came in today...still waiting for a couple little parts coming in and then should have it all back together. Will also make sure all bolts are good just to double check.

Couple more clips are on the way along with new fuel lines. Then i'll fill her up with fluids and will nervously kick it over for the first time!

Exhaust installed...

(https://i.imgur.com/q9NUpx8l.jpg)

Now i'm just waiting on a few parts to come in to finish it all up.

Parts on order right now:
- carb clip for the throttle cable
- clamp for the vent hoses (including the one on the side near the front sprocket)
- bottom exhaust bracket/damper
- condenser clip/bracket
- new fuel tank vent hose
- fluids

once everything is received i'll finish up the clips and vent hose routes, oil and install the filter, get the plastics on, fill with fluids, and will attempt to start her up!

Did some of the plastics last night (front and rear fenders, number plate, side covers)

(https://i.imgur.com/3Wktpo8l.jpg)

I also noticed i do have a small oil leak from the side cover...which i kind of figured as one of the prior owners had bent where it mates together. I'll run it as is for a bit and will then take the cover off and fix where it's leaking and put another new gasket on. Not a huge deal/concern.

Post by: mjowen on September 18, 2018, 01:48:09 PM
Got a couple more things done tonight, nothing special...

mounted the tank and bled the front/rear brakes. Noticed the front brake was all ghetto rigged up so i'll be ordering some new levers tonight (might as well get a clutch lever, too). As you can see in the pics...definitely not stock. Will order the mounting bolt/nut as well as the adjustment screw parts.

(https://i.imgur.com/rh5FTprl.jpg)

As for the tank...it's mostly mounted. Found out today after some searching that you can't buy the strap screw separate nor could i find the specs for it (or the tank button) so thank you very much to Umberto for measuring the bolts on your tank so i can get the parts needed at the hardware store tomorrow!

- Fluids came in yesterday
- Radiator shroud bumpers/dampers come in thursday or friday
- Levers and the oem adjustment/mount parts will be in friday or monday (ordering tonight)

I was really wanting to have all the parts in and kick it over friday or saturday but that might not happen until next week if the remaining parts dont come in.

End is in sight!!!

Still waiting on parts to come in...but was able to get the tank/seat bolts done.

My tank was missing the screw/bolt for the strap and it was rigged up with some type of allen bolt for the seat button.
For some reason - you cannot buy these bolts separate from Kawi nor do they have part numbers for them so you can even see what sizes youre dealing with.

Umberto was nice enough to provide some measurements to me so i just put together a couple bolts/nuts/washers that would work. I mounted the seat earlier to check fitment and it'll work just fine. The strap also works just fine hooked onto the washer and the frame.

Used an m6x1 40 screw with a large head, a 1" washer, and two nuts on bottom (i was going to use a spacer so it looked nicer but they were out of the spacer that fit what i needed). For the bottom i used a m6x1 25 screw with the same head and an m6 washer and it fits perfect.

(https://i.imgur.com/zAOQoaYl.jpg)

(https://i.imgur.com/iIS8liXl.jpg)

I also tracked down the small oil leak and it is in the inner clutch cover. When i first did this rebuild and split that cover i noticed there were two gaskets on there - i'm assuming the reason for that was the leak. Normally i'd try and grind it down and get everything to be perfect but i'm guessing it's warped so i'll just follow suit with the two gaskets and that'll be fine. Ordered another gasket in today so i'll take that cover off in the next few days to fix that leak.

Just have to get the parts in and should have more of an update :)

I have done a number of dirt bike flips off of Craigslist, and I've seen some really poor repairs, but this one has to make the hall of fame.  To quote Pcmg, "How many PBRs did it take to make that?"   :-D

Post by: mjowen on September 20, 2018, 12:53:07 PM
Yeah... The bolt that is holding the lever is just a fully threaded Bolt that barely fits and locks the break up when bleeding. The "adjustment screw" is just a rusted bolt. And if looks like they just used some jb weld or something to rig the lever.

New parts come in Monday lol

Well...

ended up splitting the inner clutch cover last night, installed the new gasket today, and got the rest of the plastics on.

Going to oil the new air filter tonight, fill the crankcase to see if the new gasket fixed the leak, and wait for the new brake parts to come in. I've also gotta order a new water pump gasket since it tore when i removed it yesterday but the local kawi dealer is closed on mondays.

 Hoping to fire it up by this weekend :)

Figured i'd post up a few pics of how it looks now that all the plastics and the seat are on...

No leaks from the inner clutch cover as of yet - poured the oil in yesterday around 530pm and nothing today. Hoping it'll be good to go for now...

Just waiting on the brake screw parts and the water pump gasket - then i'll fill it and hope for the best as i attempt to start it haha. Brake parts should be in today or tomorrow and the gasket should be in thursday or friday.

Sent some pics to a girlfriend of mine that is going to do the graphics for me as well so we'll see how those turn out. Since she's doing them for cost for me, i gave her creative freedom to kinda do what she wants based on the bike...trust her completely!

Lemme know what ya think so far

Alrighty!

The newest problem...the front master cylinder is definitely not for my 1999 KX250.

All of my front brake parts came in today...not even close to the right fit. I went through a few random year bikes for other models and it appears the cylinder is from an older Honda CR250 (1992-2006). Makes sense since the shock was also put together with random honda parts.

So! instead of getting a new master cylinder that will fit my bike - i'm just going to get another new lever and adjustment screw that matches the Honda master cylinder. Will be much cheaper and it'll still work.

Ugh. this thing is going to be the death of me.

A lot of guys have tried Honda master cylinders and say it is an improvement over the stock Kawasaki one.  You might be pleasantly surprised.

Just need to make sure I know which one it's from lol...ive looked at the schematic a million times and there's a small difference between the one I have on the bike and the one in the pic

The one on the bike has a single prong where the brake line connects and the one in the diagram for oem parts has two prongs

I'll take a pic of mine and posted in a lil bit.
I'm runnin a 12 CRF450 master on my '00 250.
The stock Kawie brakes suck, but with the Honda master, they'll practically lock up if you breath on the lever...super touchy and strong.

Yeah, I kinda figured it was gonna be...i looked at the parts diagram for the 2012 crf and it was a bit off. Ugh.

I think what I'll do is order the adjustment screw and lever for a cr125/250. Will be like 16 bucks. If that doesn't work then I'll just use the ghetto rigged one that came on my bike and just replace the rusted bolt

Appreciate you taking the time to post the pics...

I think the one on mine is from a cr125/250

I sent some pics to a friend of mine that works at a Honda dealer so he'll. Check into it tomorrow.

Hoping it's for a cr and not crf because I just got impatient and ordered a new lever and adjuster screw hoping it's right...
Title: Re: My 1999 KX250 Build
Post by: Foxx4Beaver on September 25, 2018, 09:37:51 PM
No problem, hopefully they're helpful.

On the plus side...that was a relatively cheap mod. I got the master for $40 on ebay, and had to buy a new OEM lever and banjo bolt for it.
Title: Re: My 1999 KX250 Build
Post by: mjowen on September 26, 2018, 04:04:28 AM
Yep...exactly why i'm going to try and just use the current setup instead of doing new.

once i get this bike "completed" and i need to do brake maintenance, then i'll most likely do a new front master cylinder/new lever/new lines - that way i know everything done. Right now the brakes are in working order so i'm just trying to use what is there for now.

the new lever and the adjustment bolt was only 15 bucks so we'll see if that works...

Title: Re: My 1999 KX250 Build
Post by: mjowen on October 01, 2018, 04:40:26 AM
Brakes feel fantastic!!

Little update...she's all done minus the graphics! The gasket came in Saturday so I picked it up, filled it with coolant, filled the tank, and kicked it over...she fired RIGHT up. Idles great, sounds great, and runs even better!

I rode it a little bit up to temp and let it cool then did it again and let it cool - havent really "ripped" into it but she flies...no issues so far!

I also ended up picking up two more bikes from a friend of mine - will be picking them up the weekend of the 13th/14th. Bought his 2004 Honda CRF250 and his brothers 2001 Yamaha YZ125. Stands, extra plastics, extra top ends for both, and a few other accessories - paying 2k for the pair and all the stuff. Both bikes only have maybe 30 hours on them. The yz125 has a brand new top end with about an hour on it and the crf has a new top end with just a couple hours.

Not sure which bike i'll be selling but i dont have a need for three so i'll cross that bridge later haha - gf is looking forward to learning to ride as well!

Awesome!...happy that's all squared away!

I can say, I absolutely love everything about my '00...and I was even considering sellin it after putting about $3800 into it....but it's one of the most reliable bikes I've ever owned....it doesn't matter if it's sat for a week, or 4 months...turn the fuel on, lift the choke, and one kick it's runnin, every time.

here's the thread..some of the pics are missing, due to the site crashing 4 years or so ago..

- new steering bearings
- new front and rear sprocket
- new chain
- rebuilt 2001 forks with speed bleeders
- rebuilt shock
- rebuilt top and bottom end
- new exhaust
- new levers
- new air filter
- new radiators and hoses
- new fuel lines
- cleaned and rebuilt carb
- new vent hoses
- new plastics
- new front and rear brakes
- new grips
- new pegs
- of course all new fluids
- new oem and matching bolts (replaced appx a third of all the bolts)

I'm sure i'm missing a couple things...

Only have to get the graphics now but that'll be around 50 bucks (friend is doing them for cost)

Pretty close to what I spent.
What "look" are you going for with the graphics?
I was lucky to find original OEM '00 graphics online...but, I'm saving those for whenever I do decide to sell it, it'll have the correct look.
It's got OEM '01 graphics on there now..another sweet Ebay find.

I'm actually giving my friend creative freedom for the graphics...she does the moto-x graphics for one of the race shops up north and also runs her own business from home so i sent some photos to her and will just kinda let her do whatever. It'll be a surprise haha.

i remember looking at your build thread back when i started mine - was a great build!

Ahhhh, nothin wrong with surprises!...it'll be interesting to see what she comes up with!...the fact that she's already got the experience in mx graphics is a huge plus.

Thanks, it was a  lot of fun restoring it...I'm ready to do a 125 '99-'02 next. I want all three "classes".
Title: Re: My 1999 KX250 Build
Post by: mjowen on October 01, 2018, 10:56:17 AM
Yeah, i trust her completely...she does some great work...took pics all around on my bike and just emailed them over. She'll do something up and we'll see what happens! I'm only paying cost for them so can always get more down the road :)

nice!!! I'd be down to do another one...not sure what i'd wanna do...

I pick up the CRF250 and YZ125 either this weekend or next weekend - they're all done so i'll just clean them up. Not sure what i'd do another restoration on...doing a matching 125 for my KX would be cool, though.

Not sure which bike i'm going to sell...i think i'm going to sell the CRF once i get it back here to Denver. Will keep my KX250 and have the gf ride the YZ125...that way i've got the one i just built and they're both 2 strokes. Who knows.

Looking forward to it...still nervous to ride it haha. It kicked over like a beast the first day and rode great when i took out for brief little rides - hoping those rings are seated nice and everything works lol. I'd hate to seize it.

Found this "late" into your rebuild.

I love these threads....it's like binge watching Breaking Bad or Game of Thrones without having to wait week after week for the progress. I read the entire thing in about 20 minutes.
 8-)

Any updates for graphics and such?
Title: Re: My 1999 KX250 Build
Post by: mjowen on October 30, 2018, 01:59:04 PM
hahaha, i completely agree...i love reading through build threads. I always hate reading them when they're first posted because i always get impatient waiting for new stuff!

The graphics should be ready next week...she had quite a few orders come in by some sponsored riders and since i'm only paying for cost i told her to get those done first, my KX isnt going anywhere right now haha. So, should have those ready in a week. I told her to not show anything to me - i'm just going to show up and she'll install them for me and then i'll get to see them :)

As a little update on the other bikes...picked them up last weekend. The CRF250R was pretty much all set and just needed a little maintenance stuff (cleaned the air filter, greased the bearings, greased the axles, and that was it)

The yz125 needed a little more love - greased the bearings, greased the axles, bled the brakes, fluid change, new gas tank (went with a 3.6 gallon), cleaned the carb, recovered the seat, new air filter, new plug, and new countershaft seal. Did that over the last week and fired it up friday evening - that thing RIPS.

The new main jets for the YZ and the KX came in today - so, will do those this weekend. Both have stock main jets in and i'm sitting at 5k feet so figured i'd get that dialed in.

Hoping to have the pics of the KX up soon with the graphics on it!

I completely trust her with her graphics and designs so i'm not worried - very excited to see how it all turns out.

She should have them done next week and then i'll throw the bike in the truck and head over there - she'll install them for me in about 20 minutes and then i'll bring it back down and snap some pics!

Going to rejet the KX and the YZ tonight

Just a quick update...i'm really slacking getting those graphics on lol

They're done but i just havent gone up to get them put on yet

Got the new main jet in the KX and YZ but havent ridden either of them - it snowed on us and has been pretty cold lately which is why i'm slacking.

hopefully soon!!!

The snow is a good time for sure - i'm thinking this winter is going to be a good one! Last winter was terrible...almost zero snow...

I've got a snowboard pass so will be hitting it quite a bit this year.

Maybe this weekend i can swing up to get those graphics done...going to do some for the YZ125 as well so might be able to get both done at the same time.

Thank you, we're very proud of him.  Golden is such a pretty little town.  With North and South Table blocking Denver, you'd never know it was that close.  It just looks like a quaint little mountain town. 

On the subject of riding and Golden, where are the good places to ride near Denver?  My son and I thought about hauling the bikes up there time and riding.  Maybe when he moves in next fall.

wow - so sorry, man...havent logged in for a bit.

I love the town. its fantastic. Theres a bar i frequent over that way, too...

There really arent a ton of places super close to denver. If you're going out during the week then i'd suggest rampart range as it has appx 100 miles of trails and riding...i was just there during thanksgiving. Saw a total of two people. On weekends it gets super busy so i usually stay away from that area.

There are a few places i'll hit near the springs (appx an hour south) and I also love heading to leadville to ride. used to hit that with my cousin until he moved to Oregon this year...

Lots of options, though.

On weekends it gets super busy so i usually stay away from that area.

There are a few places i'll hit near the springs (appx an hour south) and I also love heading to leadville to ride. used to hit that with my cousin until he moved to Oregon this year...

Lots of options, though.
I figured there were lots of cool places to ride, seeing the terrain and all the open spaces.  Picking a good one that isn't super crowded was going to be hard without some local help.  Sounds like Springs or Leadville would be our best choices.  Thank you for the help mjowen!
