high idle

  1. YFZ450 & YFZ450R General Talk
    I have a 2014 yfz 450r that idles high after touching the throttle. The bike will start up and idle fine until you give it throttle, then it will rev up to between 1500 and 2500 rpms. After a few seconds the idle will come back down to normal. Any help will be appreciated
