i just wanted to know if i need to do something with the jetting, every time i ride and let go of the gas it back fires like crazy, unless i pull in the clutch. It stalls every once in a while not terrible though, i have 145 and 150 main jets, and have a hmf slip on, is it suppose to back fire alot. any suggestion on what i should do if it is not right.

i dont think im lean, due to the fact that my exhaust tip is pitch black inside, and when it is first fired up, i can see blackish smoke come out, but when it warms up it goes away. do you think it would be a good idea to get a header like a powerbomb and rejet it with maybe a dynojet kit

Well if you're under 2k feet you're not too rich on your mains. Starting up is your pilots/fuel screws and won't tell you if you're rich on top. If you're sure it's not jetting then start looking for exhaust leaks.
