the problem isn't that the motor is lugging, the problem is a rhythmic pulsation that only occurs between 2,500 and 3,000 RPM in top gear.
I agree. Mine does this exact thing. I suspected it was just a harmonic that happens to occur in that situation based on the power pulse and the relative RPMs of all the power train components.
Neither the Dealer nor Honda will "fix" this. It's not a problem, just a characteristic of the bike. We are spoiled. A Goldwing rider would notice this. I don't think a Harley rider would notice this, however, since the bikes they are used to have an over abundance of "character."
