MZ/MuZ Riders

Just trying to fit a new exhaust gasket to my TS250 - it did not have one fitted when I bought it.

The new one is made of copper and is a round section, the problem is that when I try and fit it the threaded collar only screws in about 2 turns and if I torque it up I am worried about stripping out the threads in the exhaust port.

Downpipe looks to be correct - it has a flared end, just wondering if the new gasket is too large in section.

Any thoughts ?

Think I may have found the problem.

Mine might have an ETZ collar - lookin on the web the ETZ collar looks longer than a TS250 collar.

Simple solution - reduce the length of my collar using the lathe.

And by the way:
MZ originally never had an exhaust pipe gasket....

Guesi - never knew that MZ originally never had an exhaust gasket, I thought that they were fitted to all bikes.

Shortened my collar by the way, and all goes together just fine now - with the gasket.

You never find it in the original spare part catalogues....
