Valve Cover Gasket Advice
Howdy - I need to get new valve cover and breather cover gaskets. Z1 has the valve cover gasket for less than half the price of the OEM. I'm cheap and need to be talked into buying the more expensive one - especially if it's better. What should I do? Thanks!Tags: None

Get a real OEM Suzuki gasket. The material that Suzuki uses is vastly superior compared to most aftermarket gaskets.
The first link below is the latest part number. There are older older part number gaskets that will work as well though.
General forum wisdom has us using grease on the gasket to keep it from sticking, that way you can reuse the gasket during your normal valve adjustment checks.

I just got mine from suzuki and I used aircraft grade gasket sealer from permitex and 400 miles still no leakes and the aircraft grade sealer is a non hardening sealer so I can reuse the gasket without tearing if need be.

On an 8-valve, I would (and do) got with a good-quality aftermarket valve cover gasket. Z1 should be fine. Mine leaks a little but the whole bike is kinda fugly so I don't care.
Engines with the tach gear in the valve cover should always use OEM gaskets, though, because the thickness is critical in that application.

Dont mean to hijack but what about "real gaskets" silicone gaskets?
They were linked to via BassCliffs site. He used them and they cost as much as OEM so I thought I would try that. I had been doing the grease/oil method but after so many pulls it seemed I always ended up replacing the gasket, just tore both the valve cover and the breather again.
Anyways everyones comments on the tach drive makes me second guess. They actually say this on the real gasket site
IF THE SUZUKI HAS A TACH DRIVE IN THE VALVE COVER, DO NOT USE A SILICONE VALVE COVER GASKET.
But then they offer the GS 750 77-79 which I thought were all mechanical tach drive so why even offer them if you should not use it?

I guess I misunderstood tach drive in the head and valve cover to be the same thing. You mean the tach drive itself is housed with the worm gear on the cable side and everything in the valve cover itself? I can see how gasket thickness would be an issue then.
I thought the problem was gasket thickness led to the cover rubbing on the tach drive gear in the thru head configuration.
Thanks for the info. I am glad that wasn't 50$ down the drain for the valve cover, breather, and stator cover.
