Honda programmable fuel injection has adaptive fuel strategies. To see if the bike is running rich, lean or at stoichiometry, just connect a digital multi-meter with min/max/average function. Take it for a spin (fully warmed up). On a flat straight-away, start the min/max/average. Stop the min/max/average before running out of flat straight-away and see what the meter says. If the average is in the neighborhood of 450mV, life is good. If it's significantly higher than .45 V, its rich, lower, its lean. The adaptive fuel strategy will try to keep the a/f ratio at stoichiometry (450mV). This shouldn't be a problem with a minor modification or two, but the fuel strategy may run out of authority if the mods are too great (for the Honda PGM-FI). Good times.
