I bought a 2001 gsx750f the clutch slips at high rpm. Still pulls pretty good down low. The oil has been changed, with correct oil. As soon as i go to pull the clutch it enguages within a finger width. Not sure if that has anything to do with it. I also adjusted the cable. But cant seem to get it to engage in a diff spot on the leaver. Do i need to replace friction plates, springs , or just replace everything and the clutch cable.
