Gasgas 250 Pro 2002 Rattle!

Featured Replies

Hi ya.

went to see a very nice GG today but when started it rattled like my 996. Noise wasn't from the clutch and it did quieten down a bit when it was warm.

Is this normal?

dont think piston slap is an issue cause its not had much use and i spoke to shop that recently had it apart for top end freshen and they said its normal.

Is it the ATF they use?

Thanks guys.

If its not had much use why did it need the top end apart? If its rattling like a 996 dry clutch i'd say its best left where it is. (unless its very very cheap).

bought bike!

checked clutch. oil was low so the primarys were clacking about whilst having no load on em. more oil and rattle has all but dissapeared. well it does when i pull clutch in.

Happy now. :guinness:

tbh my Honda sounds sweeter and is 15 years older!

Hello there,

It is normal for the PRO motors to have a clutch rattle from new, due to the very narrow clutch gears and with them being straight cut. Pulling in the clutch should quieten the noise down, usually completely. If it is a 2002 model, the gearbox is full at 450ml. Always use either a mineral oil, 10 weight or a good ATF rated to Dexron III.

Bye, Peter B.
