Cam Plugs and valve cover gasket for KZ1100 Spectre

10 Jun 2025 08:52

Hi Folks,
I've been to PartZilla, Revzilla and Z1 Enterprises looking for a valve cover gasket and cam plugs for my 1100 Spectre with no luck.
Does anybody know of a source for these parts?
Is there any quality difference between Vesra and Athena gaskets?
TIA
Bill

I looked at CMSNL in the Netherlands. They show a Kawi cover gasket (PN 11009-1205) for $57.66. Fitment for all J-model engines up through 1990 P-model. Cam end plugs (92066-1106) at $20.55/each. Fit above models and up through 2000 P-model.

Later, Doug

I recently purchased some aftermarket ones from Webike that are black anodized. Sexy looking, but I cannot yet attest to their sealability. I am pretty sure all the J engines use the same plugs, save for the finish. The polished ones can be made black pretty easily. The only Athena gaskets I have seen complaints about are the green base gaskets.

Both PMC and M-Tec gaskets at Webike.

Athena gaskets, even things like for a valve cover, use inferior materials compared to OEM. The OEM gaskets are higher density, and coated. Athena are more porous, tear easily.
