Hi bro, FYI, 14/36 has got the same ratio as the stock 15/39 final drive ratio. Cheersjustkir said:there's no modification made on the speedometer? i am not that free to do that.........hahaha
im using sprocket 14-36
reset my air/fuel screw to 1 3/4
and a kitty (black) cdi
that's all....but i still think that the speedometer error....
