Hey all, I'm from Greenville, S.C. I just got a 96 VN750, it really is a great bike. Just had a question about the popping, I tried the marbling trick but there really was no change. Is there a way to get the bike back to factory quality, maybe rebuild the clean air system on the bike, or the carburetor? I would imagine that it would not be that detailed but I really have no idea. Any help would be greatly appreciated. Also if I were to rebuild/modify the bike in order to get rid of all the popping, what would it entail and about how much would it run me?
