[SDK-123]

I have a relatively new PCC Amor 50 with a 50cc GY6 (139QMB). When ever I get to speeds higher than 30 mph I get an awful sound which is like almost clicking but at a higher rate. See attached link (at 7 seconds). As a note, I would have taken actual video, but I could not get the CVT cover off and get it to start with out grinding starter gears.



I am relatively new to these machines, and so I was thinking it could be the valves, a bearing, variator weights gone bad, clutch issue, I read something about a CVT limiter washer, and I just do not have any idea.

Any help is greatly appreciated.
