can anyone help with a clutch issue im having, 08 yz450f and i ride pretty heavy on the clutch. but not that bad. the prob is - for the first few laps the clutch slips, then as it warms up its ok. then as it gets really hot it seems to start slipping again. rode today, and at the end of the second session, the clutch was slipping so i took it out and i did notice it was very dry , although the plates was not burnt or dis-coloured. i think the prob when its hot are the springs are losing tension. but why does it slip when its cold?? anyone any thoughts on this??? cheers. mark.
