Compression Test - ZR-1 Net Registry Forums

tf95ZR1 · 11-01-2015

I borrowed a Snap-on Compression Test kit from a buddy. It has
(4) different 8" long hard rubber hoses with one end threaded for the spark plug hole
and the other end an air compression fitting for the gauge.

The threaded end has a thick rubber washer, but with our deep-
sunk spark plug seats there is no way to get in there and tighten
the hose down. Is finger tight OK?

I also saw you can get rigid extentions. Is this what you guys use?
Thanks,
Ted

Speak for yourselves

Finger tight is fine and flexible rubber extensions are fine
