Oil leak on my 1982

I have a 1982 I have a 1982 Kawasaki Kawasaki KZ440
That appears to have a small oil leak at the valve cover gasket or breather cover O-ring I think I found one online but when I looked at the description it said that it was in an OS gasket that would fit my KZ440 And a 900 so I’m just trying to figure out if they happen to have the same breather cover or am I missing something in the wording??

Part description on eBay says:
“The par NOS Genuine Kawasaki Breather O-Ring KZ400 KZ440 ZR900 KZ ZR 400 440 900 LTD ABS t number for the NOS -O-ring IS
(PO.NO.— 92055-1020)”

So will this fit my 1982 kZ440 Valve cover/breather cover gasket/O-ring????

And if not if anyone can leave me in the right direction it would be greatly appreciated!!

, Thank you,

Jim

For some reason I cannot attach a picture it says that I need to complete the( CAPTCHA ) Which I have no idea how to access it where it is what it means or what I need to do any help on this matter would be greatly appreciated as well!!!!!!

That is the correct part number for the breather cover o-ring. It also fits the fuel evaporative canister on the modern Z900 (not KZ900). I do not know how old that NOS is, but you can still get brand new ones from Kawasaki.
