Just more thoughts from my experience.
I THINK I went to the 2nd hole at 20k on Thumper.
I went all the way past 79k before I opened it up again.
It wasn't noisy, but performance was down. The tensioner was a little past half way on it's travel.

Put it back together. All I really did to it was the chain and adjust the valves (first time I ever did that too).
It's a little peppier now. Not like new, but better than it was.
I THINK my performance issue was a because of the chain stretch throwing off the timing and causing low compression (maybe?)
I got 150 lbs of compression when I was done.
