  1. YFZ450 & YFZ450R General Talk
    I have a 09 YFZ 450 (carb) I’m not that good on working on quads but I know a bit so bare with me but everytime I start my quad the idle is high and I can hardly rev it while idling I free like im banging over the rev limiter but when I put it in gear it and ride a bit it does sound like it...
  2. 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
