Well, this is an educational point of light for me. I never thought variations in valve clearances would affect power output. Thinking about it I guess tighter valve clearances may have the same effect as advancing the cam timing. Interesting to be sure! My valve lash is set dead in the middle of the adjustment range and that may be why I'm so happy with my bike's midrange torque.
Thank you. See, I'm not too old to learn.
