One other thing you can do is baseline your compression tester on a similar bike that is known to be in good condition. You may find that 125 psi is a good reading using your gage and technique at your elevation.
Have you repacked the silencer and checked that the holes are not plugged with carbon?
If everything else checks out you may have to work on the jetting. I have an '01 EC300 that has required much leaner jetting than normal to get it to run right and some other 300 owners have found the same.
