when you say it whines to much? are you talking about the noise it makes? also got to remember you are turning to sets of chains and the bike is geared way down from the stock set up. which i think the factory setup was geared way to high for the little amount of horse power it was putting out from factory. from the video it sounds and look perfect for her to ride. has long has it still has the factory governor on it and you change the oil couple times a summer and oil the other stuff i told you about......:thumbsup:good to go.......
where to you have to put the shims........:shrug:
