Oil in the airbox...?
 

I've seen a thread for this bt I can't find it for the life of me...

I changed the air filter a couple of days ago...when I split the airbox a considerable amount of oil was inside?? Probably no more than an few tablespoons... but i don't know why or how it got there?

Is this 'normal'?

Is this on an XT600? Your engine oil level is probably too high, check it when the engine is hot, not when it's cold.

Yeah I,ve had it on my xt600 before when I overfilled the engine oil, recheck when hot and you should be fine. I had overfilled it that much it was leaking out the filter cover !

Thanks...yes indeed..overfilled
