An update... I could not really find a compression tester adapter so I bought another compression tester that was made for small engines and it had the 10mm adapter included. Ran the test and here are the results:

Test #1, all as is:
Cylinder 1 (left side as viewed from riding position) - ~70 psi
Cylinder 2 (right side as viewed from riding position) - 0 psi... did not even try to move the needle.

Test #2, used my other compression tester gage just to be sure, same results.

Test #3, squirted a tad bit of oil through the spark plug hole.
Cylinder 1 - 160 psi now.
Cylinder 2 - still sitting at 0, not even moving the needle.

If my thinking is right, at least on Cylinder 1, it has bad rings. Cylinder two could have so many things wrong with it I will not know until I take the engine off the bike and start taking it apart to get a visual.

My thinking is if I have to take it all apart (and as long as there is no scarring on the cylinder walls or any other fatal damage), is there a rebuild kit I can get for these engines? Something that has new rings, crank bearing and all those goodies?

Thanks.
