05 vn750 has terrible gas mileage
I have been having a problem with my 05 vn750. It has 6k miles on it and a custom exhaust. I'm getting terrible mpg with the bike. A little under 30 mpg. Another possibly related problem is a bogging i get with mid/high throttle. Sometimes I get this bogging and then sometimes I don't. I'll be riding along and suddenly the bike will have full power again and the bogging will be gone. This has happened twice. Another possibly related issue is first gear. Sometimes i will have trouble accelerating in first and it will bog and I really have to give it throttle to get it going and then other times I do not have this issue. I have put half a can of seafoam in a tank of gas and ran that and that seemed to help a little bit but I still have the main problems. I plan on cleaning the carburetors and seeing if that helps. Does anyone have any other suggestions?
