Can anyone tell where I can obtain a KZ650 (cerca 77-80) sump gasket. I know I can get one from Athena-Ad in Italy but it is in a complete gasket kit.

So can'd a local Kawasaki dealer get ahold of one?

Without a part number, eBay is the only source of leads that I found:

Here's a seller who has a Kawasaki sump gasket but not for the KZ650. Click the seller name to contact him to ask him if he can get one for your KZ650.:

And here's another eBayer selling another type of gasket for Kawasaki... he, also, may have a connection on the sump gasket:

Not a for sure answer, but hope it helps.
