Question about BMW K 1200 GT Motorcycles
Well, the shim adjustment must be done, the question is are you too late? I presume that you are talking about valve shims, which is how the valves are adjusted. Valves work their way into the head, over time, and this closes the clearance, when you hold the valve slightly open, the valve and seat get damaged.This is the time to fix the low compression cylinder, as it will only deteriorate more from this point. Likely a valve issue...And it appears that is what your mechanic is indication. NO MORE adjustment means that the valve has worked its way into the head too far. Valve job time. Sorry.
