I know running lean means you have too much air/not enough gas. What are the ramifications of that? Is it just loss of power?
And the engine will run hotter. Whether that's enough under normal circumstances to seriously damage an engine would depend on a number of factors but since Honda offers three different jets for their EU2000i to best match air density at various elevations it would seem to only make sense to take advantage of that and install the recommended jet based on elevation where you expect to use the genset. I'm near sea level and wouldn't normally camp above 5000' so this isn't an issue for me but for those who expect to use their genset at much higher elevations changing the jet seems to me to be worth the effort.
