I'm glad I did, I found a valve that was burned and not seating properly.
Prussian Blue tells the story:
The valve is toasted and is only a matter of time before it left me stranded somewhere.
This GS has 103k miles.
If you plan to keep the bike get both heads done. New guides, new exhaust valves, grind/lap intakes, new seals.
Good for another 103k
