CRF 150R Oil Questions

[chem_dawg]

So I've seen things about putting an MA or MB type of oil into clutch side and flywheel side, but which goes in which ??

Basically, I've heard that you put 2 different types of oil in your CRF150, one on each side... can anyone tell me what side and what oil please? :cool:


And do valve covers need to be super clean ? Cuz I didn't remove any carbon deposits on them, but figured they were cool cuz thats how they came out ?

10w-40 "motorcycle" engine oil is fine for both the engine and transmission. If it is really hot like summer weather, you can use 20w-50 "motorcycle" engine oil in the engine, and 10w-40 "motorcycle" oil in the trans. If you plan to use a synthetic oil, make sure it is blended for "motorcycle" use, and that it is formulated for "wet clutch" transmissions. And Yes !!!! the cleaner, the better !!! Any loose dirt or debris left to enter the engine is NEVER a good thing. This can cause premature engine wear or failure.

but what about the MA and MB difference?



How would I go about cleaning off these carbon deposits ??
