SYNTHETIC OIL?
Yes, as long as you are well beyond the break in period on the bike you can run a Wet Clutch safe synthetic. Amsoil makes an outstanding synthetic 0W-40 that specifically made for newer 4-stroke motors. It will reduce your temp, power gains across the whole range, and shift much smoother. They claim you can also run it in your motor twice as long as normal oil if you motor is equipped with a filter. Just stay away from the automotive type with the anti-friction additives; it will fry your clutch.
P.S. No I don't work for Amsoil, I just love their product.

I know some people use Amsoil. Just be sure to use the right kind of oil. Been told to stay away from anything with friction modifyers.

Out of curiosity, what does the owners manual suggest for the Rubicon? GN4? HP4? or either one???
The reason I ask, is that HP4 is a synth/petro blend, where GN4 is all petro. Honda never recommends HP4 for any of its bikes that have centrifugal clutches, like its autoclutch bikes. The reason being, that synth can make the clutch slip.

Reconranger, maybe you haven't heard about the HP4 debacle. There used to be one HP4 with Moly. About a year ago, Honda started offering two types of HP4, one with Moly, and one without. According to Honda, the HP4 without Moly is acceptable in any machine they make...period. The Moly stuff is a no no for machines with fiber clutch plates of any kind (don't know what it's good for, maybe your lawnmower). Myself, I just stick to good old GN4 in my bikes, and change plenty often. Then I know I'm safe.

dzzy- Where you been??? What debacle??? HP4M (JASO MB, with moly) is for use in the CRF450/250 dirt bikes and TRX450R quad ENGINES only (not any transmission). These have a "split case" where the transmission (wet clutch) is seperate from the engine. You run the really slick stuff WITH moly in the engine, and a JASO MA oil in the trans. This is the way engines should be designed!!! My compliments to Honda!

Yes Reconranger, forgot about that app for HP4M. It is a good idea. I admit I work primarily on streetbikes this time of year. The debacle is that Honda sold us HP4M (when there was ony one HP4) for several years before telling us (or finding out) it was bad for fiber clutch plates, then waited several years before changing it. Before the CRF type engines, there was basically no use for HP4M except scooters and lawnmowers.
