So, I want to do a compression test on my motorcycle.
If Poopdaddy weren't 100+ miles from me, I'd ride down there and have the expert do it.
But living way up in Cumming, I decided to try the test DIY style.
Borrowed a compression test gauge from my brother, who was an automotive mechanic before he went to college for engineering.
It's an old one, 50 years or so, and made in the USA. Made for American engines whose spark plugs have threads
that are 9/16" x 18 (fine thread pitch).
The plugs for my 1990's Honda motorcycle use a metric M12 x 1.25 thread.
Where can I find an adapter to use this compression tester on the cylinder heads of my bike?
