Unmasking the Aerospace-Grade Head Cover Gasket: The War on Thermal Drift and Seepage

The stock cover gasket on the Katana is made of paper.
It shrinks a lot when heated.
One option is to apply liquid gasket sealant in advance to areas prone to shifting,
but doing that makes it a real hassle to remove the cover next time (lol).
In fact, applying liquid gasket sealant near the cam chain tunnel
is a very effective way to prevent leaks,
and it’s a spot where the manual often specifies applying it.

Now, for the most effective solution:
reusing the gaskets from the domestic-spec 1100 Katana SR and SY models.
These have been changed to a metal material, and while they’re a bit pricier,
they eliminate any shifting or blow-by and provide excellent sealing, so I highly recommend them.
In response to requests for reproductions, a manufacturer that produces high-quality aftermarket parts has created a metal-coated head gasket.
Although they cannot be used on some models, this should be a lifesaver for many users.

Have tried these gaskets they truly are excellent.

It's thin metal with rubber ish material bonded each side is far stronger and retains shape better than OEM.paper.

If you have the 16 bolt pattern seals better at the cam tunnel front, as doesn't squeeze out.

So far have able to reuse it once.

Hi John,

Thanks for the tip on these, if they ever answer back about postage I'll buy a few. I have a 16 bolt and 20 bolt so both types will be helpful.

Cheers mate.
 
I bought a cam cover gasket and a few small extra parts recently and air postage was only $21 with tracking 7-14 days
