No but other engine damage might be and if that was tied into valves being out of spec and you had neglected to do a valve adjustment check at the specified service interval then that opens the path to deny a claim.
I had to adjust the valve clearances on one of my trials bikes this year, the symptom was that the bike became progressively harder to start, then eventually would not start at all. Have 2 of them so after swapping out almost every assembly on the bikes to test them the valve clearance adjustment apparently was the root problem. Adjustment was simple, compression test was the best indication of the problem :/ In hindsight I should have done the compression test first.
