compression numbers and stuff

Those compression numbers are serviceable, no reason to tear the engine down just yet.

Regarding rebuilding the engine, it's not hard, just requires being detail oriented. I’m not familiar with what Suzuki did in particular but its typical for some manufacturers to associate the bearing journal size with some color code. It’s a fairly simple matter of matching up the color codes on your crank with the required bearing shells required.

With those compression #s and the #s coming up wet, I would look into using a bit of Seafoam or the like in the oil and run it for a bit and give it a few oil changes. The rings may be a little gummed up and when clean could bring the #s right back up.

Ride the bike. Comp nos are fine. I've had bikes that have run ok with not much more than half your figures.

What is seafoam? never heard of it. Where do you buy it?
I just changed the oil to 20w50. Maybe some hard riding free up the rings?

Servicing the plain bearing cranks is not difficult. All of the new high performance Suzukis have them.
It is all done with number / letter codes and bearing colors.

If you're really determined to find something to tinker with, well, that's up to you. Your bike. Have fun.
