R1200 LC valve clearances due at 12k, 24k etc miles, so if not done previously I'd be checking them now.
Had mine dealer serviced & checked at 12k, 24K, I checked mine at 36k recently & still within tolerances, Easy enough to check IMO. Most don't need adjustment apparently. I decided if they did need adjusting, I would have the work done by an Indy, as the procedure beyond my comfort zone
