Hi everyone. Im just in the process of finishing my all out kx5 build just thought I would share some pictures collect some feed back from some of the more experienced guys. I started with a 92 with a blown motor piston shattered into the bottom end seized the motor solid. These first few pics are the frame swingarm and linkage powder coated with new moose racing primary chain guide, alba racing chain wheels, msr swing arm bearings, pivot works linkage bearings, and an msr swingarm chain protector.
-
Next I moved on to the motor. Full bottom end rebuild with tusk clutch all new bearings new crank, hot rods con rod, full seal replacement, offroad innovations cylinder ported just a little, cleaned all the power valves, minura top end gasket kit, zpc sports silicon rad hoses, new aluminum rads, all new fasteners for almost everything, wiesco piston, boyesen factory racing stator cover, driven shift lever, running motul 2stroke trans oil. Uni air filter. Fmf gold series expansion chamber with power core muffler
-
Next I moved onto a acracing sub frame. I also decided to run a silicon line up above the air box with a mini open element air fiter for cramk case ventilation and installed my moose racing brake lever. Ive called this "the very clean kx5" because I spent more time scrubbing every bolt, nut, and relating component with varsol then actually assembling the bike and I pretty much for the most part bought the best of everything I could get for it. Id like to tell you how much ive spent so far but you would all vomit profusely if I told you. Unfortunetly the riding season in edmonton alberta is short and brisk so I need to get this running and get some hours on it soon. Due to that I will have to use the old beat up plastics:( very sad day but life goes on. The project is far from over. This winter will be all new plastics and decals, excel wheels front and rear, new tires, wavy rotors and new pads, rear shock re build with new spring, ims foot pegs new pins and springs, and definitely a twin chamber fork swap im thinking yzf450? And advice on that would be golden. Also a steering dampener. Oh and also a magura hydrolic clutch. Im curently waiting on my boyesen rad valve mm grips and pro taper clutch lever to finish it up for this season. If there is anything ive missed please feel free to add it to my list and I will oblige. Thank you for reading. Ill add a pic of the bike when its all back together

So far it looks like you have done a nice job.
Congratulations!
Cost?
That is subjective at best.
What does it cost for a new bike?
You can't go down and buy a new KX500 at your local Kawi dealer for any price.
And then there is the joy of a job well done :-D
-
Ya thats how I feel about it aswell
-
lookin sharp. whos rads are those?
-
Ebay rads. Theyre by a company called auto power and they actually fit pretty nice compared to what ive heard about other aluminum rads. They are cheap 100 bucks
-
Old plastics are back on now. Discovered that I had the wrong clutch cable and still need 2 chain o rings but thats it some mix and coolant and ill be layin the roost :evil:

Not to mention the wide eyed stares of fear from other riders as you are sitting on your K5 and the dirt is jumping off the ground as it idles in a rare controlled moment of restrained fury... Soon,,, soon... :-D
Nice bike!
-
Thanks. At first I hated using the old plasti s now ive grown to like it. Everything performance is clean new and looking sharp and the plastics look 0 fnk5 given is got a really race ready appeal I think
-
This friday will be the day. I just need to pick up that clutch cable and some brown riding pants and ill be good to go. Ill let you all know how it turns out
-
Looking forward to it.

Well it fired up after about 6 kicks. I tested it shortly on the road in front of my house. Not really a good test ground at all. I hit second gear seemed to bog in the power band not sure enough though. I think im going to take it to the bike shop and get them to go over it just to be that much more sure everything is in check.
-
If it wasn't fully warmed up they can bog especially so if your jetting is off.
What is your jetting and altitude?
Did you use old or new reeds?
What type?
-
The jetti g is a 155 main im going for 168 I think. And low end is a 60 going to switch out for a 58. Im 2200 feet above sea level but I also ride at sea level aswell. I took it out today were I ciuld actually open it up and it was fast for sure. It needed to warm up and get revved a few times but it seems to work good. Im also going to bump the mix down to 40:1 after I burn this tank of 32:1 im running a boyesen rad valve iridium plug fmf gold series.
-
Motorrad gave me a combo that worked very good on my SM with a stock engine.
55/168 stock needle 3rd position.
That has proven itself for me up to 1500 ft...
But as always, beware.... every bike runs a little different.....
I just installed a 41mm carb and that jetting does not work at all...
-
Good those are good numbers. Being that everything is clean and new and I have no other problems I should beable to start there and hopefully wont have to do to much re jetting. How about those pre ordered jet kits speced out for your bike? I havent heard anything about them. Good idea or bad?
-
Ok so I finally got it out today and ran it hard through all the gears. Its fast considerably fast. But its not "unridably fast" I expected more to say the least. Either im missing some power somewere or I just thought it would literally be like riding a stupid death rocket. I guess the best way to tell would be to ride a different kx5 and see how it compares. It definitely gets from 0-60 in the blink of an eye though. It doesnt feel to me like the rear wheel is always trying to get infront of the front one which is what I was lead to believe about this bike. Im thinking a trip to the local dino is in order. I also run a 51 tooth in the dack and a 13 in the front so the torque should be even more intense. Im not sure if im disapointed that its controllable or happy that its actually ridable. Further investigation required I would say.

I went down to a 55 on the pilot didnt help at all it just idles a bit lower. The only problem ive had so far is a broken rad mount on the side I had to force the bottom bolt in. It wasunder some tension so I figured it might fail. Unfortunatly my tig welder doesnt excist so I had to use the good ol' jb welder. But thats alright 60% of the time it works everytime if you know what I mean 8-)
