i have a ttr90 and would like to improve the suspension. I have bought a kx65 parts bike on ebay. all that the bike has is the frame and front and rear suspension. no wheels, motor or anything else which is ok, all i am interested in is the forks pretty much. The bike was mislabeled on ebay and it was said to be a kx60. when i saw it so cheap i immediatly bought it without really looking hard at it. after looking at more of the pictures i noticed it was actually a kx65. i was just curious if anybody has ever done a conversion like this. I know it wil be a huge project but i will probably do most of the work so it will be fun. What exactly needs to be done. Ive seen where some people have cut off the heads of both bikes and welded the front end of the other to the 90. after all this is done how will it effect the bike? will the clamps hit the shrouds or anything? and i was also wondering how much longer the 65 forks are over the 60 forks?
