hey honda, yurs makes like a "woooo" sound at light revving in neutral like mine? cause mine didnt make it before, I also asked the dealer and they said on my motor the h22, the Tbelt follows a tight pattern by the bottom and that the grooves on the belt need to get worn in, an that it will go away, I will give it some time and see, its not a prob, jus annoying, what is your situation like? an what motor is this on?
