Mobil 1 VTwin in the engine
Mobil 1 75w90 gear oil in the trans
HD Formula Plus in the primary although in a pinch I'd probably use any dino 10W40 or 20W50 oil. The primary don't need no expensive synthetic. It's just keeping the primary chain and clutch plates lubricated and cool.

RE: Primary oil
Red Line MTL in primary, Red Line Heavy Shock Proof in trans. and will do Red line in motor next change.
I tried Red Line in trans first and it made a big diffenence in trans noise and smoothness. Decided to try MTL in primary 2 weeks ago. Made things much quieter. Shifting noise is almost none. Since both Red line products have made me happy I will go with it in the motor next oil change.
Ride Safe,
Mike

RE: Primary oil
I have used 5w30 once in the primary....roadside repair. It worked fine, but there was a little slippage. I believe it was due to energy conservation. I recommend at a minimum 10w40 though.
I mainly use ANY diesel 15w40 in the primary. It is inexpensive and can be found almost anywhere. However, sometimes I end up using any 20w50 laying around the shop.
For the past 20+ years.....the primary gets 15w40 diesel oil
transmission gets 80w90 GL5
engine gets 20w50 for warm months and 15w40 for cold months
