welcome to BHQ

 

switch your plugs and see if it changes to the other cyl. and clean the carbs

Synchronize the carbs (adjust cable to they open and close at the same time) and make sure the throttle cable is not in a bind anywhere. Make sure the choke tube is in place. Black hose that connects the carbs together.

I would advise you to perform a leak down test as well, if you haven't already.

welcome to my nightmare...im in the same situation...was running fine before the rebuild except psi difference..rebuilt it and did a few other mods and slapped it back together and it doesnt run right....right plug is super lean....ive tried everything...so im finally doing a leak down...i just buiilt my tester..i recommend you to do that. if you have an air leak then you will run super lean.

Does it not hit all through the rpm range? I had it happen just off an idle and carbs were out of sink but the other one would kick in and run like it was supposed to. I guess if they are out of sink bad enough it could be that. I think that it's a vacuum leak.
