...itll lock up? it'll shut itself off and lock up and is super hard to turn over. i was riding in some trails and got on the open road and opened it up to cool it off after we started cruising and it sputtered i checked the gas and it was good, i started to leave and it killed on me before i got off the clutch. if you have any suggestions please write me back. thanks, matt
