You should lap them and install new valve guide seals.

Can you find a link for some new valve guide seals? I found some on ebay but they are viton are these worth it? the spacers and everything looks new. did a leak test and there was bubbles so I will be lapping the valves.

Get the Vitons. They don't harden like the stock ones. Avoid NOS rubber. They're 30-40 years old already, not worth the time and money.

Courtesy of KZr member steell:
76-79 KZ750 were the "B" model, single disc front and rear with wire spoke wheels.
1980 KZ750G, pretty much the same as the "B", but with rear drum brake and mag wheels.
1981 KZ750 twin models don't exist.
1982 KZ750M1 CSR, same motor as the "B" and "G", with air injection into the exhaust, with wire wheels and rear drum brake.
1983 KZ750K1, same as M1 except for belt drive.
1984 KZ750K2, Canada only, same as K1.

Good Fortune!

I called z1 they dont stock the twin gasket kit anymore. Im positive the one im looking at will work. I have a 79 750g with the mag wheels and rear drum brake. engine is b3

No eBay APP ID and/or Cert ID defined in Kunena configurationthis is the gasket set I am looking at. From the picture it appears to be right. I contacted the buyer and he said he didnt know if if fits the 79 twin.

They look right to me.

Here is the Athena set available. That's the one I bought and the blue colored gaskets failed rapidly.

Vesrah is supposed to be better than Athena, but I have not used Vesrah personally.

Also on ebay with free shipping.



Same kit on ebay showing correct picture of gaskets:

here is my build thread. So i am confused, the athena set is the one you bought or the one from ebay? which set did the gaskets fail on is what I mean. Because I would pay extra to get gaskets that wont .
