The PF is for perimeter frame, since I could build a stock KX500 and it would be an SF.
I finally got to the point where I could start this project.
The chassis is a '92 KX250 which was my primary ride for over a dozen years. I scored an '08 KLX450 front end for it on Ebay. The engine donor bike was an '87 KX500, but I have since gotten enough stuff to make the engine an '89 to '04.
This bike will be used for trails, not MX, and since I am about a 7/8 scale man, I will mod the clutch cover for a Rekluse Pro.
Enough with the background. I started the basic engine mounting a few days ago. I bored for the swingarm bolt as a starting point to get a baseline. Obviously, the front mounts were not even close:
Before and after them being cut off:
The mockup before welding:
After the welding:
The lower mount was so close to where it needed to be that I decided that it was a waste of time to try to move it like I did the front mount. I could have left it alone and used an 8mm bolt, or shave it a bit oval (.020") to use a 10mm bolt. I went with the ten.
I have learned a bunch from this site, and now is the time for me to start contributing! Any questions for me will be answered to the best of my knowledge. Any suggestions that I get are welcome as well!
