I think whether or not it is helpful depends on why you're doing it. In the case of my wife's bike (which I did the resistor mod to) her bike had an aftermarket exhaust and muffler and the aftermarket exhaust had no place for the oxygen sensors. Whomever installed the exhaust must not have known about the O2 eliminators or the resistor mod because we found the O2 sensor zip tied up inside the fairing. Since they were constantly reading ambient air oxygen levels I'm guessing they were making the bike run waaaay too rich. Removed the O2 sensors and did the resistor mod and the bike seems much more responsive and stronger in the low revs. Never calculated gas mileage on it before (or after) the mod, but I bet the gas mileage has improved too.
