Copper Head Washers

1976 Kz900 with 1015 block. I have annealed the washers for reuse but have a question. Do ALL 12 studs have to have a copper washer under them or only specific ones? Search as I might in both manuals I have, i can find absolutely now reference to this.

Thanks.

I have to disagree with the usually astute wireman. All 12 washers are copper on every KZ/Z1 I have ever taken apart. It would make some sense to use steel on the inside eight studs but I have never seen a steel washer used. The only ones that need to be copper, really, are the outside studs as these are where the oil will come gushing as they sit in the oil journals where oil is pumped up to the cams.

guys, I took the top end off my G1 classic this weekend and there were NO washers. I had 16 10mm bolts.

I was just taking the cam cover off to replace the gasket and the rubber plugs. Are you guys talking about this or a different part of the motor?

Now I'm scared ...:(

You are talking about the cam cover, they are talking about the head studs :laugh:

I think it depends on which model motor you are working on. I remember having motors with all copper washers but the last few I've seen have steel washers. Sorry, I can't tell you which motors were which, but I've seen them both ways. Lots of help, huh?

A spare 76 KZ900 motor I picked up had never been apart as near as I can tell and it had all 12 copper washers. The original motor in my KZ900 just had copper washers on the outside 4 holes, steel on other 8. Since the cylinders had been bored it obviously had been apart and I really suspect the steel ones were not original.

Great news, we're ALL right! 76 KZ900 calls for 12 COPPER. 77 KZ1000 calls for 2 copper, 8 steel. Found this on www.buykawasaki.com .

Thanks all.
