1978 RM400 cylinder and head


Recommended Posts

I'm restoring a 1978 RM400, coming along really nice. But I'm a bit concerned about the head/cylinder match up. It has a round head gasket that sits a bit recessed in the head itself. But when i put the head on the cylinder, the head does not touch the cylinder. It rests entirely on the gasket itself. The cylinder sleeve sticks up past the top of the cylinder itself, and the gasket sits on this. So when you look at it from the side, you can see daylight between the studs and cylinder liner. I hope I'm making sense. I don't see any other way it could go on, but it just doesn't seem right.

Anyone have any thoughts/pictures to help me out?

Thanks
