I've been riding scooters since 2006, and prior to my Yager I've owner a Yamaha Vino 125 and a Kawasaki Ninja 500R... I also have a Yamaha Morphous that I got in 2007. Neither of the Yammies had noisy belts like the Yager. My Yager's belt (or should I say, the belt/transmission housing area) makes a noticable (but not *extremely* loud) WOOOOOOOooooooooh when I back off the throttle from say, 45mph (~6k rpm) and begin to brake to a stop. At first I thought it might be the rear brake dragging or tire noise, but I had someone help me and I put the bike on the center stand and revved it up to 5 grand then closed the throttle, and sure enough, a WOOOOOOooooooh type whirring sound came from inside where the belt goes. Is this normal for a Kymco, or do I need to have the thing looked at? I have about 450 miles on it so far and I have done all the break-in services per the manual, including changing the transmission oil.
