Engine and trans oil are seperate.......this is one of the great selling points for these engines (Honda 250/450's). Can't believe there is anyone out there who doesn't know that. How many hours have you put on it without an oil change????

:thumbsup:

First of all, this is my first thumper, and second ive only been riding 4 hours on it. So that is why I ask(time for oil change)... I know about the seperated oil chambers(so the small metal pieces gets in the oil filter and not the crank shaft, Genius!!) Should I put SAE 10W 40(Motul) in both? or is the engine better of on something else?

Sorry I insulted you, but you really didn't phrase your question very well at all!

In the trans, you can run a motorcycle specific API SG/JASO MA engine oil, or one of the trans specific lubes (like you would in a 2-stroke trans).

In the engine, you have additional choices. I would run a API SG motorcycle oil that is either JASO MA or MB (if you can find one).

Which Motul product are you considering??? Motul oils have a high percentage of ester synthetics, which makes them excellent oils! I would probably run 5100 if I were running Motul. My personal choice is Maxima Extra, also an ester synthetic for both the engine and transmission sides. http://www.maximausa.com/technical/lubenews/LubeNews2002.pdf http://www.scooterhelp.com/genmaintain/crankcase.oil.html

One thing to consider, you are still in the break-in period, and although this is controversial, some would say you need to stick with a petroleum oil during break-in.

1.How about the bel-ray Sae 80(Gear saver)In the tranny?Or is this too thin for an thumper?

2.Not sure what it`s called, will check it later.

3.I may have phrased myself wrong again, the bike is one year old. I just bought it from a guy, I have only been riding it for about 4 hours.

Buy any good oil that has a MA rating and use it in the motorside. If you ride it long and hard use the heavier grades. 15W,20W-50. 10W-40 is good for general use. Change it alot regardless.

In the tranny side the choices are huge from ATF to specific clutch fluids. IMO I try to find a good oil designed for the clutch that is light enough to shift good and also hold up to the heat of the clutch slipping. Change this oil also alot....
