Gasgas 280 Pro 07 Changing Gear Oil

Featured Replies

Hi can anyone please tell me how much gear oil to put in when i change it . shouid it go to the top of the glass on the clutch casing?

NO NO NO, 350 cc max....is plenty for an 07 Pro.......Any more just blows out the breather when the oil gets HOT and expands..........

This topic has come up many times in these forums and no definative answer has ever seemed to be given.

The general concensus is anywhere from 350 to 450.

Personally I use 450.

I was told 350 when i got my 04 250 pro and thats i've always put in! Even in my 07 300. Haven't changed the amount.

I agree with D. Sileo, put too much in and it'll just come out of the breather. I've seen it happen.
