High Altitude modification for Honda 2000s

Has anyone felt the need, had the urge and/or modified their Honda 2000 generators (or any make/model) for high altitude?
At home (7200'), our twin set up with parallel cord seems to power the Coleman Mach 13.5 unit.
Are there forum members with a different experience at this elevation or higher at (9-10K') and needed to modify? thanks.

    Hey thanks, for all the input.
    Since spark plug fouling doesn't appear to be an issue, I believe that we'll leave 'em stock (use both w/ the air w/ fresh gasoline w/o ETOH but w/ stabil, winterize at the end of the season and use the 2000W inverter for the little microwave).

    I've used my two Honda 2000s at over 10,000 for 8 years without modification. When at altitude, we have to use both generators to run the microwave or air, and we have to be careful about which combinations we use.

    Changing the main jet is hardly a "modification" ... details in this thread.

    I had the head shaved .060 on my 1500 and it really helped. Flathead engine though. Had the head shaved on a couple of Witte diesels .090" and it really helped at 11,200 feet altitude.

    I put the high alt jet in mine and after using it at 9K feet. It ran fine but rich at that altitude.
