I loaded my bike this past sunday morning to ride in Dallas (3.5 hrs away) got down there and was warming up my bike and heard an awkward noise coming from the engine. I was pissed, and thought if it blows it blows. So I rode all day, the bike ran perfect. Anyway last night, I was determined to find the culprit, I thought the valves needed reshimmed or the motor mounts needed tightened. Both check out ok, pieced it all together . Fired her up, it sounds like its coming from the bottom end around the clutch. Any thoughts?
