EN 250 2005 Jetting
Bruce Robinson said 2005-05-02 15:49
What jetting is being used in this bike for competition. It seems that I should be able to get a little more out of the top end, but possibly there is rev limiter or something for emissions that is preventing the last 1/8 of throttle to rev to the sky. I have the stock needle in the 3rd clip with a 172 main jet. Up from 165 stock.
