I am 16 and have a 50cc moped. I was taking the exhuast today, and as i was undoing the bolt, it snapped! so half the bolt is in the manifold. To make it worse, its snapped flush with the manifold so you cant even get a pair of pliers on it and twist it out! this has really p***ed me off as i am selling it this week! Anyone got any ideas? Thanks, Ben.
