Okay so a little back ground first. i stopped racing motocross 20 years ago. At that time i was racing a 93 KX500. My wife at the time didnt like the risk and we just bought a house and were starting a family so racing and the K5 went. 20 Yrs later i am divorced and the kids are doing well so i thought it was time i started riding again. Dont want a 4 stroke so i bought a 2001 kKX250 gave it some love and have been riding it since May. Man have i missed riding dirt bikes. I really wished i wouldnt have waited 20 yrs to start back up. Here is the 01 KX250 i have been riding.
It has been really fun to ride and i have been having a blast but, I really miss the bark of the K5. So i found this place and thought i would try to do my own conversion. I really like the 99-2001 KX250 chassis. So i figured that is the chassis i would use plus then i would have 2 of the same yr chassis so they would share all of the parts minus motors.
Here is the donor bike i just bought this saturday. i picked it up for $500 it is a 2000 KX250 that has a blown motor but everything else is there and in pretty good shape.
Now all i need is the K5. lol
Thanks for all of the info.

:-D... thats what i was also called on race last weekend as i rode my ´87 with the 360cc engine to the 3.place in the evo-cup...
in spring i sold my good old ´97 kx250 that i rode 11 years. and i can say, it needs not the newest bike. only a good rider to ride it realy fast ... 8-)
now i own a restored and light modified ´83 kx250, ´87 kx250 and my just from ebay-parts and new spareparts builded kx500sf conversion in the ´93 kx 250-chassis, what i started only with a frame. because i ever wanted a k5,( but i had not enough money in 2003 to buy one of the last european models) ...all bikes run very smooth and powerful... :mrgreen:

both bikes are in real good shape at the first look... i say, safe the 2000 kx250-engine and also fresh them up for your spares.. the time will come, when its getting hard to find oem-parts for the 2001... :wink:

Picked up a 1990 K5. It is suppose to have a fresh topend with about 5 hours on it. It runs pretty well needs some carb work and jetting. Has plenty of compression. Rest of it is pretty rough. I think it was one of those where he just did what he had to to keep it running not much else. I am going to need a new carb intake boot. I have read that the KDX one works better for the conversion. Is there a paticular year that works best. Or what about a boyseen rad valve for the 500. I paln on using the 2000 KX250 airbox. Over all I am happy with the purchase though and I think it will make a good donor. Plus i will give it much love. It just feel better to have a K5 again. 8-)
Thanks for looking and the help.
