Ok today I dug threw some belts and found two! An old stock pretty worn belt and a almost new extreme belt, I tried the almost new extreme belt and it was slow with lots of rpm (like 25mph top speed with motor screaming) the stock worn Yamaha
belt was like it was geared high like bogging and slow. The belt I had on it (parts unlimited cheepy) was good speed just right rpm but it skips and vibrates. The extreme belt was not skipping, the old stock Yamaha
belt was vibrating but no load clunking like my cheap parts unlimited
belt!! Maybe I should just get
a new stock Yamaha belt!
