I am working on a newly purchased 81 R100RT for a friend. Both exhaust valves have severe recession, 1 mm and 3mm.
Surprised to see that on an 81, but the air injection was damaged, without the feed lines being plugged, so that may have caused the recession.
Thinking it may need seat replacement as well as new valves.
Last time I did an airhead valve job was in the mid 80’s.
Any recommendations on shops that you have used recently?
Several shops from previous threads have closed or no longer do head work.
