Anyone ever use Schaeffers Supreme 7000 20w-50 or 9000 5w-50 in their bike?
Just ordered a case of the 9000 and plan on using in Engine and Primary. Tranny will still have Amsoil 75w-110 (SVT)..

 

DO NOT use anything with moly in the primary. I will ruin the clutch in short order. It would be fine in the motor, just not in the primary.

 

I wouldn't use a 5w50 in a Harley.

 

The Texas heat will shred a 5w50 in short time. 20w50 for the heat, that 5w50 would work for cold morning starts in Canada.
