Hey again! So I tore it all down. Now I'm not sure whats the problem. So far all that I found is the little rectangular reed valve was missing 1 out of 2 screws, and around that area down there is where I found the most of the shredded metal. also, I'm not sure if its a problem but the actual shaft on the crank has the slightest bit of play. Mainly I just don't know what to replace so please help! I don't want to put it all back together and not replace the main prob. Thanks in advance! Also, I was thinking it was the crank bearing. But after checking them, I'm not sure that's the case. The special roller bearing, (When viewing from the back of motor, left side.) feels ok, but I'm not sure how smooth it should be. But yeah, please leave some feedback. Really desperate to get riding again. Thanks!
