i have a 1982 it 250 that has a fresh top end rebuild on it that still isn´t running right. it usually starts the second or third kick but when i go to grab a handful it doesn´t get on the pipe until you turn the fuel off it really starts to run good. I have looked for answers and no one seems to have one if someone could help me that would be great i would really like to ride the hell out of this bike.
