So good news bad news, I pulled out the little sliver a metal that's all it was, about 1/3 inch long, no leaking, unfortunately the tap tap tap sound is still there, going over by now to see if I can see anything hanging up, both tires look clean now. The tap tap is only happening while the bike is moving clutch pulled in, nothing to do with the engine thank God, I guess possible stuck brake caliper? Not sure, balance tire out of whack?
