I'e been riding atv's/dirtbikes for over 30 years and never had a clutch slip unless it was worn out. I still have my 1982 ATC250R with a manual wetclutch and it has blasted Dumont Dunes more than any bike I have owned.quote:

The Honda ATV clutches are pretty picky about oil from what I am told,
My currant bike is 2001 Kawasaki Mojave. To combat camshaft wear I've gone back to "car" oil. I broke the new top end in with 5w-20 and added 5 ounces of Torco magnetic friction reducer.
Even loaded with the Torco stuff my clutch didn't slip.
Currantly running Delo 15w-40, the new stuff w/Moly and no problems.
Oh and since switching to "car" oils my camshaft wear looks to have stopped.
My neighbor has a 1999 Honda 400ex with a wet clutch and a new KFX 400 and they both get Chevron Supreme 10w-40. No slippage. Same with his sister in laws Z-400.
I think the whole "your clutch will slip with car oil" deal is blown out of proportion.
