GS750 Exhaust manifold

[ybot1966]

Can anyone tell me whether the exhaust in pipe is only held in place by the finned clamps or is the pipe pushed into the head? as i have a pipe that moves left to right about an inch

The end of the pipe is pulled in against an exhaust gasket in the cylinder head port by the two bolts for each header pipe. I would suggest the gasket is missing.

If you look at the attached link you will see how the header pipes fit into the cylinder head, just disregard the info on the modification that the thread is talking about. It is fitting a 550 header set to a 650 head so does not apply to your bike. But it will give you the idea.

Thank you for the info sir it does feel like something is either missing or corroded behingd the pipe

i took of the finned clamp off and the the exhaust had three gaskets in the hole two fat copper rounded type and one flat steel one, presumably these were not prized out previously and the manifold should have just one gasket?

Yep. Copper O-ring type gasket.

Exactly

Pull out those old ones and get 4 new ones (one for each hole, of course)

I was looking to get new exhaust gaskets do these have to copper with rounded sides rather than the silver flat faced ones, i think the outer size is 46mm not sure what the inner Circumference is?
