There's a couple people on the SOHC forums that tend to think that motorcycle gauges produce more accurate numbers.

I'm not sure what I believe; I'm just raising the question if anyone has compared the two.

Rodney's same gauge was used on my CB750, and it also gave low compression numbers on my 12,000 mile CB750. Sometimes, I tend to second guess the tool I'm using.

Also just read that he hasn't adjusted his valves yet. Adjusting my valves on my CB450 (which were so tight that I couldn't fit any filler gauge in) raised my numbers by 15 PSI.
