In previous strings, I complained about the severe detonation problem I was having with my '72 750. Suspecting this was a carburetion issue, I switched to a single Mikuni. Amazing what a difference and confirms the Amals were running way to lean. No more pinging.
I plan to continue using the Mikuni while figuring out the problem on the Amals. I may be terminally old school, but still think the twin 932 Amals out perform a single carb. What I've done so far is strip and clean the Amals in an ultrasonic cleaner with lacquer thinner, then blew out all the jet areas with compressed air. The slides are in perfect condition having been sleeved by Mike Gaylord so mechanically there is no issue with worn parts. I'll assume the problem is setup and getting the correct jet sizes.
Been running 240 mains (230 is stock) #25 pilot, #3 slides (stock) and needle clip in the middle groove. That worked with the old gas....what jetting and needle position are you 750 combat owners using (Amals) with this gasahol that is getting good results.
Thanks,
