That's a good list. Best not to use a multi grade oil in the gearbox though, causes clutch drag. Use a straight 10 weight mineral oil only, or an ATF rated to Dexron III, never a synthetic. Re-fill with 700ml.

I always run fuel/oil at 50:1 with a mineral oil, but then I am old fashioned and like to see a 2 stroke smoke a little. My preference for fork oil is 280ml 5 weight in each leg, I guess this is rider dependant.

Bye, PeterB.
