Yes, you can tell by the before and after injector cleaning report.

I'm no tech but the compressor didn't even fail on you, correct? Personally I wouldn't clean the injectors unless the compressor failed. The optimax is a picky engine but that's pushing it.
The compressor IS failing..... it just hasn't died yet.
If it wobbles too much, you WILL see crap going over the piston and into the air rails. All it takes is enough wobble to let the piston start to scrub on the cylinder wall and you start to see metallic filings being pumped out of the compressor, where there is no filter to trap 'em... That can screw up the fuel mix for one or more cylinders, which can overheat those cylinders, which turns this into a MUCH more expensive repair job. Seems irrational to even consider running a compressor that has a known problem, no matter how minor. Problems have a way of going from minor to major in very little time.
With a two-stroke, you can't take chances on (a) running lean - that will kill the powerhead; (b) running hot - again kills the powerhead; (c) running with oil problems - which will again kill the powerhead. Stumbling, rough idle, harder than normal to crank, all things that can be put off for a bit. But nothing related to the big 3. And I didn't even get into mentioning water in the L/U.

AND, remove the two oil filters in the lines between the compressor and the end bearings. Cut 'em open and see if they are clean. Make sure there is no trash flowing that direction in addition to down the airway. Something that is right in the "middle" of the motor like this needs to be handled carefully. IE it dumps air to the injectors and oil to the motor bearings. Neither will tolerate metal pieces.

Ok I guess I'm going to take the compressor apart and cut the old filters apart. Does anyone have a guide on what to look for and how to disassemble, or should I just get a manual for that?
Respectfully, just tear the compressor apart (completely). Every bolt and piece that removes with a wrench. You're replacing it anyway- not like you're going to hurt it.
You're looking for any shiny or gray particles (or oil stained with shiny or gray particles).

I dug into everything and here's what I found20190512_111225.jpg
Might have been some grime in the filters. Could have been metal but not sure. Either way barely anything. No debris at all in the cylinder.
The rod bearing and crankshaft needs inspected, that were the problems start.
I haven't been able to get that end off. Undid the bolts and pulled the clip off. Am I missing something?

I was talking about pulling the whole top off of the compressor as one piece, I have not broken down the top bearing assembly sorry.
