Thanks for the info. Tomorrow I will look into it more and start ordering parts. I will reply with what I find.

Once again thanks[/quote


Get a side cover dude. :laugh:
The oil coming around the left side is a classic example of the cam chain galley O ring being broken. It always seems to come around the left side, could never figure out why. The exhaust gaskets are copper and they can seep oil. That's not your problem. The early KZ 1000's had steel valve guides and were notorious for smoking at start up and fouling plugs. The stock seals get hard and leak because of exhaust gasses getting to them.
Here's what happens;
Exhaust seals fail
Exhaust gasses fill the top end over heating it causing the other rubber components to harden and fail.
The O ring around the cam chain galley hardens and breaks.
Bad valve guide seals generally cause smoke at start up but clears once warmed up. They can cause fouled plugs. If the smoking lasts longer than that, rings are indicated as well.
Time to pull the head. Depending on the condition of the guides,valves, seats, cylinders and your wallet, you may be able to get away with new seals, valve lap and rings.
The cam chain is another matter. This is no where to cheap out. If the rollers or guides are hard and or worn out, replace them. A broken cam chain WILL destroy a engine in a heart beat. I and a few others have been through this. It's no fun.
Gaskets and hardware;
I use one piece head gaskets. I've found the after market O ring in their sets don't last. I've re used a Kawasaki O ring but it too failed after a while. If you go two piece, spend the extra money and buy the OEM O ring not NOS. They are 30/40 years old and unreliable.
Put up pics as you go and we all will be happy to coach you as you progress.

You will find the Liska cam chain parts are 1/2 the price and will last much longer than stock if they will fit your engine.
