YAMAHA CHOPPER PROJECT
DESIGN | MAIN | ASSEMBLY

2005/02/02:
Sean finished tearing down the engine as far as he felt comfortable (it ran when we started, so we never planned on rebuilding the engine anyway) and replaced as many o-rings and gaskets as we could get at. The carbs got a rebuild. With the new air filters, the top end breathers could no longer be routed to the airbox, so we shoved on some cheap small filters, though they barely squeeze in between the frame and carbs.
A new sump filter was especially important, as ours, just like every XS650 in the world with the original sump filter, had a tear in it. It was a bad design, and Mikes XS sells a new and improved one.
We still need to re-jet the carbs for this new air intake and (yet to be complete) exhaust.

With the engine buttoned back up, we dropped it back into the frame.


Jared came by to try it on for size... He's 6'4" if you're wondering how that frame's rake and stretch fits someone. (I'm 5'10")
