R80 Valve seats

Post by Chris in BC »

1981 R80 G/S Tried to buy a replacement exhaust valve seat. No longer being produced by BMW, I was told. No longer in stock at Moto-Bins. (they still stock the 1000cc ones)
Luckily , my non official shop had one left in his stock, so I am going to be OK

How have people dealt with this recently? Know a source or do you find a machine shop to make one from scratch?

I can't be the only one to need to refurbish an R80 head. I mean it is only a thirty-three year old bike, just getting into its prime!

Thanks, I like that Swiss site.
Sorry , I was looking at your answer and thought you had given me https://www.bmwbike.com/index.php
then I got back and found you mentioning Max BMW.

Guess it depends on how much stock each place actually has. When I queried Moto-Bins, they had removed it from their catalog and claimed they couldn't get any more. My shop had contacted the local BMW dealer and they claimed no longer available.

That's strange, when you can still get /5 and even /2 stuff.

More demand. People are now doing no cost barred restorations on those older bikes, not so much on R80s. Most often R80s get upgraded with R100 parts as originality isn't as big a deal......... yet.
