New to TT, I have an 01 drz400 with fuel in cylinder, petcock seems to be working properly. I have fuel coming out of the header, pipe connection and bike is vapor locking if left over 2 days without starting. Recently put fmf q pipe when trouble started. I will check carb, 3x3 mod and add jet kit this weekend, any help on stopping the leak. Fuel in oil as well. HEEEElp
