It seems to me that anybody that has half a wit about mechanics and engines would naturally re-adjust the valves after the initial start up and run in. The final tune-up..carb, timing and valve adjustments are normal things you do and re-due after a few miles and then at scheduled periods. 11 months and probably numerous thrashings on the motor could be part of the situation that was not mention?
Defective gaskets, leaky soft plugs and the like are all things that can pop up in any build, and although shouldn't happen they do and can show up after the initial test run at the factory.

Donald the truth will set you free!
