I have a 2006 Suzuki ltz400 with a 40cc Duncan big bore kit (I’m pretty sure). The problem is whenever I increase the RPM (by speeding up or even just driving it) then pull the clutch in and let off the gas it quits. This is a major problem because I cannot go around tight corners on my track without it shutting off. Really I can’t even slow down without it shutting off and I have to constantly rev it when I have the clutch in. Please help!
