True or False?

[Laurus]

Someone told me that there are two kinds of baskets for the cilinderhead, a metal one and a rubber one, true or false? If true, what are the differences between these two? How do I know what one to use?

Thanks in regard.

I'm not sure what you mean by Basket? Can you post a picture of the part in question please?

You must mean gasket, right?

Just use the original (metal) Kwak ones and apply some bond on both sides.

cheers,

Ow I am so stupid, off course I mean gasket

But what's the purpose of the rubber ring under the gasket? Do I have to place this one too? Or isn't this original? So the original metal gasket with some bond must be enough?

Thanks for the assistance

Sounds like you may have a head that has been modified to fit an O ring, post a picture of it and we'll be able to tell for sure.

Huhm, interesting, what does such a modify mean?

It's about this bike, a '94 kr1s with only 7000km...:

Unfortunately, can't get the pictures working properly.

Looks like a normal head to me?!


Is that the bike that used to belong to Jim (ZL900 from motor-forum.nl)?

If it is, how come you had to take the head off again, he did repair the one barrel, didn't he?

cheers,

Or maybe not
Looks like a mark or shallow groove in the head where an O ring would sit but O ringed heads I have seen have a much deeper machined groove.
I'm sure a couple of people on here have had O ringed heads (Jan?) and will be able to tell.

Yes, it's the former bike of Jim indeed. He didn't repair the one barrel but sold it with a broken one (and piston)... So I bought it in pieces, only have to fix the barrel and hope it will be fine by then..

[Charles]

Is there an O-ring groove next to the combustion chamber? The pics aren't that clear. Jim said his bike was all standard, so if the head really is standard, just buy an original Kwak head gasket.

[Laurus]

The head doesn't have a O-ring groove, the barrel does, but I guess that's normal...

Edit: some small research tells me, a O-ring groove in the barrel isn't normal?

No, it's not. You got a pic of the barrel? Have both barrels got this groove?

[Laurus]

Both barrels got a groove, looks like the barrels have been tuned too... One's got an inscription at the bottem..

[Laurus]

Anyone familiar with these barrels?

damaged barrels repaired...
?cast iron/steel cylinder liners pressed in - alternative option to reconditioning electrofusion plated bores ?

what do the undersides of the barrel look like? will be easier to determine if it has been linered from that view.
