So i saw an add in sport rider, (or one of those mags) a couple months ago, about a throttle cam, sothat the first 1/4 twist gets changed to 1/2 twist and the last 1/2 happens quicker. Anyone know where i can get one of these? i googled it with no luck, think i might be using the wrong verbage, but my bike seems to be accelerating or slowing, with a VERY small window in between.. thanks
