The title explains it. I've got experience and bikes. However, the vn750 is a new breed. Just picked it up at the end of the last season. Rode it through fall put it away for winter. I'm doing some customizing on the bike. However, before the next riding season I need to swap out the tires and figure out what's wrong with the engine. I'm pretty sure it's nothing to do with the engine itself, but the carbs. My front cylinder runs fine. However my rear cylinder really only kicks in between a third and half throttle. I checked all my cable tensions everything's fine. The guy I bought the bike from said he dip the carbs and rebuilt them. The carbs both look brand new. I think it may just be bad jetting. Just looking for some advice.
