Leaking gas cap.

The right track, for me anyway, would be to work with the dealer and importer to replace the entire tank, asap. Last year I bought a new, left over '09 Aprilia, had a small bubble in the finish. Nothing structural, or major, strictly cosmetic, on a $2000 gas tank. Had a new one in less than a month, installed, full and free. GasGas should step up and do the same.

Sure they should step up, but if I can fix with a simple o-ring...I don't have a problem with that either.

Looks like our local o-ring supply house has Viton o-rings at least what I can tell from their vague website...will find out tomorrow for sure.

Mick,
Did you solve your problem? I'm in the same boat with my 2011 EC300...

I'm still in the same boat. Have a new Genuine GG cap in the spares bag that I haven't even opened cause I know it'll do the same as the last 2. I have still been running the last one with no rubber seal at all and it has minimal leakage.

I pulled the stock rubber out and screwed in on fairly tight. Sloshing a full tank around in the garage resulted in surprisingly little leakage.
I'm going to ride it like that and check the result.
