I always used, and always heard reccomended, the HP4 10w40, the black bottle with the red cap. Either one should be fine though, just don't mix 'em.

Ahhhh and you ride a suzuki? LOL .... good one

As for your question I've been running HP4 10-40 w/ moly for the engine (silver bottle) and GN4 10-40 (black bottle) for the tranny and have NEVER had an issue not even valves IMO thats the best combo. Very importand MAKE SURE YOU DO NOT PUT THE MOLY IN THE TRANNY SIDE IT WILL RUIN YOUR CLUTCH.

The black bottle is GN4

Run 10W-40 in it. Your choice on GN or HP. The GN4 is their standard fossil oil. The HP4 is full synthetic. The HP4M should only be used in the engine side. The moly is said to make the clutches slip.

I use HP4M on the engine side and HP4 on the tranny side. Both 10W-40.
