Interesting aside about 650 motors in 500 frames

So, with a 650 motor in the 78 Standard frame, the 500 carbs can not be put in between the motor and the frame without removing all the engine bolts and tipping the motor forward slightly. I know I didn't have this issue on the 82 Custom... anyone else experience the same?

For my XS650 Yamaha I bought new from "Sporting for Less" and had to change all of the jets. They said the carburetors would be jetted for the 650, lied to me and others not even close. Anyway I bought VM34 round slides and they work very well after jetting. I ported my heads, stock cam, and two into one selfmade headers.

Cheers, 50gary

So you're sporting dual 34mm carbs?
