Check your carb sync

Yep..check your carbs...its running richer on the left side. I'd check the compression in each cylinder when you get it put back together, just to get a baseline; and to make sure its near the same on each side.

loks like washout to me. richer on the right. where do the airscrews run the best? what's your needle set at?

 

what do the plugs look like?

as was said, did you check the compression after the rebuild? then go to the carbs, looking for syncing problems. what about the crossover tube, that can be looked over sometimes as well after a rebuild....

I've never been a believer of the washout theory. But I could be wrong.
