Interesting - I had not heard of instances involving classic K-bike engines. Maybe I've lead a sheltered life?

Burning an exhaust valve is much more common than head breakage on oilheads.
Lean running (high heat) and oil consumption (carbon buildup) on higher mileage engines cause this.
Fuel enriching systems reduce the lean running effects as the engine runs cooler.
I've seen many more 1200 oil cooled models swallow valves. They have much better fuel management but run lean as well.
Below is a typical burned oilhead exhaust valve.

Thanks for the info. I've not had any of the oilheads and later boxers being a K-bike person, so this is new information for me. It certainly speaks to the need to watch valve adjustments and running conditions.

Getting back to the OP’s issue... The bike is old enough to have minimal value in parting out, and the OP is going to need to make a decision on what to do—part out, scrap it, or repair it. As I pointed out earlier, I expect the fastest and least expensive path to making the bike a runner again is to swap in a used engine. Beemer Boneyard has a couple of 1996 engines on hand; can anyone verify that a ‘96 engine can be mated to a ‘98 transmission and chassis?
Best,
