tried to start it up tonight. but it wouldnt start. then there was this sound and after that a sound that sounded like scraping. looked at the chain but the chain was fine, wheeled it back to the gaurage. saw a line of liquid on the ground. not sure if it was gas... the rubbing was the clutch plates. the three nobby parts are rubbing the casing. dont know what to do. im really really upset. i was looking forward to riding it somewhere other then around the block.
