Grease no, it will spin right on to the clutch plates. How about a touch of ATF. Or if you like a bit of 20wt non-detergent oil as used in air planes and compressors. If you have a mark three than engine oil 20-50 is good for the self adjuster for the chain and than also for all other parts in there. Use the lube that you going to use in the primary.
