We are having problem with throttle bog, from fully closed to quick snap open. This bike is completley stock. We are running 93 octane pump gas, i know this is part of our problem, but i know alot of people not running VP racing fuel. We change the main jet from a 172 to a 170 to try and lean it out a little, adjusted idle up just a bit. it was a little better. I am going to move the clip on the needle from 3 slot standard to second spot and see if that will help out, anybody else having this problem and what did you do? any suggestions guys please help me out here.
