Higher than what? I have used mine from sea level to 9,000 feet with no jet changes and no problems. I would not consider changes unless I was going to be permanently relocating to an elevation above 6,000 feet.
I read in the manual that if you jet for the higher elevation, that they wont work at lower elevations. Be sure you are only going to run at high elevations if you change the jets as you may have problems running it at a lower elevation. I have the Shop manual for the EU2000I and can look up the procedure for you if you want.

You need to buy a high altitude jet from a Honda service center. It replaces the stock jet located inside the bowl of the carburetor at the lower end of the main nozzle. (small screwdriver & small fingers helpful)
I would only do this if the generator is to be used consistently above 5,000 ft. If you do this mod, make sure you change back when you come down to lower altitudes or the leaner mixture can cause engine overheating. (Per the owners manual)
Even with the modification, there will be a decrease in performance at higher altitudes.
FWIW I live at 5,000 ft and use my EU-2000 between 5,000 & 8,000 ft on a regular basis with the stock jet and have had no problems.

Replacing Carburetor Jet for High Altitude Operation
Honda EU2000I
Tools Needed: Flat blade screwdriver, 8mm socket, and 10mm socket.
1. Turn ENGINE SWITCH to OFF.
2. Turn FUEL TANK CAP VENT LEVER to OFF.
3. Remove the MAINTENANCE COVER.
4. Remove the AIR CLEANER COVER and MAIN and OUTER FILTERS.
5. Drain GAS from the carburetor by loosening the SCREW on bottom of carburetor bowl. Close DRAIN SCREW when finished.
6. Remove HEX BOLT holding the black air box on. (8mm)
7. Remove TWO NUTS holding the air box and carburetor. (8mm)
8. Slide AIR BOX off carburetor studs and fold down out of the way.
9. Slide CARBURETOR out being careful with GASKETS (two, front and back).
You may have to remove one or two hoses from their brackets in order to slide off of studs.
11. Remove CARBURETOR JET by unscrewing with flat blade screwdriver and replace with NEW JET. Do not overtighten.
12. Reverse procedure for reassembly.
Elevation Honda Part No.
0 – 4000 ft, 62
4000 – 7000 ft. 60
6000 – 10000 ft. 58
Carburetor: KEI HIN
Note: Engine horsepower decreases about 3.5% for each 1,000-foot increase in altitude. The effect on horsepower will be greater if no carburetor modification is made.

I live at 6500' and most of my camping occurs betwixt there and 10000' (mostly around 8500'). I have two eu2000's...one with standard jets and one with high elevation jets (not sure which jet, bought lightly used). The one with the standard jets wouldn't even power my charger (ProSine 2.0) at 60A on the DC side (~720W) with the ECO on. It would bog down, then charger would shutoff, then gen would wind back up, charger would kick back on, then gen would bog down.....well, you get the picture. With the gen with high alt jetting, it runs the charger with no problem on ECO.
