vinson 500 drive belt

[tits]

my friend has a 2003 vinson it has 3000 km and the belt has never been changed if he was to put a new belt would he gain a little more top speed or would it not make any diff i know it would grab better during take off but im not sure about top speed

It would not make a difference unless his is so bad it is hurting performance. If you want more performance than normal you need springs, weights, rollers, etc.

do you think it would be about time for him to change it
