On my 2001 XR650R , went to my dealer that I bought my bike from and ask what oil to use this winter for ice racing. He told me to use spectro ATV 5W30 oil and that it would be ok. WRONG !!! I rode the track for a few hours and my clutch wouldn't disengage when I pulled in the clutch lever. Took clutch cover off and cooked my outer clutch basket to the shaft. Had to buy a new outer basket, bushing and thrush washer, luckly the shaft was ok. So learn from my mistake and stick to honda oil only and HP and not HPM.
