Z250 C fuel cap gasket mystery

Hi,

Just wondering if anyone knows what part number this should be, the C model has a different tank and cap set up compared to the other z250 models. Externally the cap looks like the ones used on z200 and z400s, but the microfiche seems slightly different - my fuel cap doesn't have the second pin shown at the key end of cap.

For the z200 and z400 models, the gasket has the part number 51059-008.

Are these the same?

Thanks.

This #11009-1051, fits just about all of the 80's bikes with the flip up lid. Do you have a picture of your tank/ lid?

That looks like it to me Motor Head.
Awesome thanks.

Here's my existing gasket, missing a chunk.

Hmmm this is confusing. Both seem like very possible possibility.
Based on the z1 website, I can see both have the "c" shaped inner diameter cross section, which was what I wasn't sure about to start with for the 51059-008.

I may just email z1 and ask. Guess its time to get some other bits and bobs too.

Will update when I get an answer.

Thanks.

The 51059-008 is the right one!
