When riding yesterday after a long run down the hyway the engine started chugging on light load,, pulled in the clutch and engine dies... Pull over, it wont idle, runs ruff, spites into the intake..... Turned ignition off, opened the tank and it clears up..... This has happened three times now... Later that day heading home, it starts chugging again, pull over and there was fuel under the tank bag. took it off and left the cap open. It ran fine after that... SO... I thinking a plugged vent in the gas cap... Is it able to be cleaned? Any ideas welcome............
