Well, I bit the bullet this week and bought a new Honda EU2000 for those extended boondocks, and I am looking forward to running the unit through it's paces..... BUT, when I bought it I asked the feller at the store about a high altitude jet for the unit, as I live (and camp) almost exclusively at 7000 feet and up. He was very willing to take more of my money for the privilege of giving me what I asked for, but now that I have it in hand, I started looking around for helpful installation instructions on the web (which I found), and it seems that many Honda owners are of the opinion that the high altitude jet is unnecessary.
The consensus seems to be that aside from the unit running a bit richer, there is no quantifiable difference in performance. So, what says the collective wisdom of RV.net? Do I go ahead and change it out, wait until I see how it runs with the current jet, or keep the new jet in my collection of things I've bought but never used?

We have run our EU2000i at 10,000' many times with the flatlander jet without any problem. But, we were not running it with a large load; probably 500 watts max. It did blubber a bit, but it didn't smoke or foul the plug.

Our experience is up to 10,600 feet with sea level jets. Of course, we didn't run it for weeks, just a few hours over time. If i knew that the unit would only be run at a certain altitude, I would spend the $2 and install the appropriate jetting. It just isn't necessary in the short term.

If you change the jet and then go to a lower altitude, it will run lean and cause damage.

We just spent two weeks at 7,500. Ran the eu2000 everyday for ours and my sister's MH. It ran our 45A converter easy. Ran pretty hard when I added the 100A converter from the MH. But had zero problems.

Why don't you run it at the altitude you camp at, run your normal load then kill the engine. Take out the sparkplug and look at the insulator.Light tan or darker color means running rich and you can pop in the leaner jet if you wish. We got the EU2000 and it's EPA and CARB certified for California use so it's probably a little lean anyway.We ran it at 8500' for a week and it never sputtered once.

I also just got my EU2000, I bought the 6k jet. Most of my use will be at altitude but some will be lower. I figured I would just change it out. As far as leaving the stock jets in go ahead. I dont think you would notice any problem unless you have a large load and even then you might not notice anything for a while.
The consensus seems to be that you should leave the stock jets in, that way you wont forget and run the unit in lower elevations thus causing possible engine dammage.

We ran ours at 8200 feet this summer. No problems at all. I do have the high altitude jets with me, but never had the need to switch them out.
