Hy there, I have Keeway Matrix 50cc and it is time to change cluth contra spring. So I want to ask what color I should choose for contra spring and for small springs? Also what weight roller I need to add? I want improve scooter acceleration (take off). All my scooter is stock. Thanks for your help. Sorry for my bad english
if your scooter is stock it most likely wont benefit from any roller change unless your rollers are completely worn out (square). putting in stiffer springs probably wont benefit much either to be honest, all it would do is make your clutch engage at a later rpm, and because the stock setup doesn't rev that high there isn't really much point. Start buy at least buying a decent exhaust.
