so my buddies and I were working on a project bike i acquired and as we were tightening one of the cylinder head cover bolts, it snapped off and left part of the bolt still threaded. What's the best thing to do? needless to say, I can't ride it out to a shop. My buddy has a drill and said an easy out drill bit should work...any other ideas? or is the easy out drill bit the best way to go?
