When it was found it had the sub frame mods already, and being that it's a 90 with an 88 wheel, I assume somebody bought this to upgrade they're 88 and was just having some fun with it. Sorry the pic sucks it's a screenshot from a video. I'll get on better ones soon!

I purchased a cheap screw in tester..

Removed the plugs and gave it a spin. I turned with both plugs out, both plugs in, and one at a time. With both plugs out I had some resistance, more insome spots and almost a free turn in others. Meaning at certain points in the turn the weight of the wrench could turn it and in others it was a little tough. With either plug in, the free falling turn was pretty much gone but I could still turn it pretty easy with just a little more resistance in spots. Both plugs in had the most resistance but it still wasn't too bad as far as turning it over with a wrench. I did hear a slight whishing sound with either plug in, maybe every two-ish rotations (I could also hear the pushing and pulling air from the plug free cylindar), and the wishing noise doubled in frequency when I put both plugs in.

You need to check on your valve clearances too before the compression test. Mine wouldn't start and had less than 50psi when I got it, reset the valves clearances and got 150psi and started first go.

I have a compression tester that had a rubber tip option, so I could just push it into place.
I'm pretty sure I got it at Harbor Freight.

Might be this one:

Well.....I used the push in attachment. After removing the radiator to get to the front cylinder, I tested the compression and it read 175 psi almost on the nose. The rear cylinder, although much easier to get to, only read 125psi... which is not great considering the manual spec is close to 190 (188+-28 psi). I was most concerned with the rear cylinder as it shows signs of light rust. The hasn't ran in who knows how long. I read somewhere that you can rub a little oil in the cylinder manually and get a better reading in these situations.

125 is low but the bike could run OK anyway. oil in cylinders is for checking the valves for a cause of low compression and to answer the question rings or valves.
