Ok, another question for the all knowing XS650 database.
I have a cylinder block that has been modified with larger sleeves for 80mm pistons and I'm trying to fit the base gasket but something doesn't seem right.
Is there supposed to be an o ring around the sleeve like in the picture? I'm assuming there is but this base gasket I have (big bore from Mike's XS) seems to rest on top of the o ring. Shouldn't the base gasket have a hole large enough so that it doesn't rest on top of the o ring. My SR500 has an o ring around the cylinder sleeve and the base gasket hole for the sleeve is big enough that it doesn't touch the o ring.
Am I making sense here? It seems that, with the cylinder up side down as in the pic, once you slip the base gasket in place the o ring should still be exposed. The base gasket doesn't sit flush otherwise.
Any help?
Thanks,
Robert
