Is the clutch supposed to spin at sometime ( without needing a new clutch ). My bikes got alot of giddy up but if I put too much throttle on the engine ( in higher gears only ), the clutch will begin to slip. Is this supposed to happen ? 30,000 miles and runs great. When do I take the bike in for a new clutch ? This only happens when I really goose it but I dont ride like a racer. I was just testing out a new ( used ) bike. Thanks
