XC to MX Build
After 3 years of owning this machine I finally have decided to rebuild this XC 2003 KFX 400 as the mx quad of my dreams. (Hopefully this build doesn't take 3 years lol)
I picked this up from a member on here who owned it since day one, raced it a couple seasons and it sat in storage since 2005. The thing was meticulously maintained, came with all stock parts, and all original receipts.
Unfortunately before he sold it the motor overheated and it was found to have very tiny metal shavings in the oil filter which makes me assume something went bad in the bottom end. I haven't decided what I should do with the motor, keep the motor all Yoshimura or go a different route. I know these motors put out massive power back in the day. Its set up with the Yoshimura 449 stroker kit, with piston, crank, gasket, Web cams, Kibble white valves and springs.
I plan on taking the quad to the local mx practice track and running it on the ice in the winter. With this thread I hope to get some ideas, ask some questions, and share this with all of you. Enjoy!
