I got my sliders in and the bike gained quite a bit over all. I was hitting 68 to 70 on a small hill that i ride every day. Its just a tiny slope but almost level. No im hitting 75 to 80 but when i get it that fast i think my belts is flapping. I have my original belt and the scoot has 16,500 give or take. It only does this over 70. I doint know what it is but i know my belt has to be stretched a little. Im kinda wanting to try a kevlar 795x19.8x30 is the size i was told to get. Does anybody have a good place they bought there belt or belts from? Thanks for your time.
