Hmmmmmm, an interesting concept. A little more work is required on the rear sub frame methinks.

Oh the rear sub frame is fully adjustable....baling wire, the fabricators friend.  Also just tacking things until you are sure everything will fit is important.

What happened is I needed mock up motor to dry build up my C&J frame around while my XR570 motor is in the hospital so scored completed XL250s for $300. Old YZ swing arm and bobs your uncle.

the genuine item sold for 9 grand not so long ago..... there were actually 2 frames produced for the 4 valve motor...I am going to claim I just found one..... of course the other 4 valve advantage is quick conversion to 500 motor.
