Gas cap seal - what's it take?

I have an 82 900SS and the gas cap leaks when you have anywhere near a half tank in it. I looked at the rubber seal and it still seams to be pliable. Are these easily replaced and should there be a second seal? Just looking for a reason this thing leaks. The cap has a key lock so I would prefer to fix this one versus just replacing it with another.

Is your tank the later style that uses the same cap as an S2 ? you should be able to get seals for them both, if not of Steves shop shot me a PM and I'll send you the link

I think mine is the earlier style. In the US our 1982 model looks like a 1981 in the rest of the world. Mine appears to have only ever had one seal, but I was thinking there may have been two and the second one has just gone missing?

Seals for the older caps are readily available from most Italian bike shops , check Steve's shop first

Yes I stock both sizes of the gas tank cap seals for twins, as well as both the sizes for singles. www.shop.bevelheaven.com

1 seal only is needed. Once you replace the seal (just remove the little screw etc it is a 2 min job) check that the cap is sitting on that little bar at the pivot correctly.. They typically do a good job of sealing up.
