    I have a 2006 Yfz 450 and when I start it, it runs perfectly but once I rev it most of the time it stays reved high and sometimes dies down. It was running good about a year ago and slowly started doing that. What do you guys think it could be? Carb is all stock has slip on Yoshi that’s it

    Been having problems starting my 2008 YFZ450. Just got it used yesterday on a trade. Was told it needed a new battery from the previous owner which I later bought a brand new gold series battery for it after the deal.

  7. YFZ Powertrain
    I recently bought a 2009 YFZ 450R with a acrb conversion. Ever since I got it, I can't seem to get the idle right.
