Your bike has fuel injection with oxygen sensors running through an ECM, I don't see how it could run lean. It should self adjust. The same as running at high or low altitudes.

I AM an expert (honda tech) and if it causes a problem (lean) then an engineer needs to be severely beaten. As long as the cataylist and o2 sensors are in place-- the bike technically should not "know". Backpressure theory is horsepoo IMO all engines are basically air pumps the more it pumps the more it goes -- PERIOD

the one exception is torque -- intake runner length and exhaust can play a part -- but it's minuscule
