Gunnut,

They all seem to say that these days. Afterall, HD recommends SYN3 in all three. I have done some investigatin' and agree with Glider that engine oil does not belong in the tranny. Need a high pressure gear oil at least GL1 and probably GL5 depending on 5-spd or 6-spd and how you ride your scoot.

I may deviate from Glider some on the primary. What I use may be a synthetic that has been formulated for use in primaries with addatives to control slippage and drag. In my case, the jury is still out on the primary chain case fluid. But I have not noticed any slippage, and my shifting is very smooth (probably more the tranny lube oil though).

TQ
