Today while I was out riding I noticed something. My bike accelerates great on begining to mid throtle but once I get about 2/3 throttle the bike acts like its spinning the rear tire but its not. The engine still accelerates but the bikes power slips, stops accelerating. I was wondering if I need to replace the clutch plates? What should I look for to tell if the plates are worn? I noticed that the clutch was dissengaging at the begining of the lever pull and it ussually starts about mid way from the bar. Could I put Hinson in the stock basket assumng that its still ok?
