    Vmax 1200 -98 Misfires

    Bor i changed the needle clip to pos 1, so the needle is as low as possible. Now it don’t smokes on idle. At first it started I had no spark right front, changed the plug and it has spark, by that time right rear stops to spark, changed the wire to a loose and it starts to sparks. I think...

    Thanks for your reply and good thoughts! The plug RR just happend to die, and it took a few hours before I noticed that. So now I got spark on all cylinders. It blacksmokes from both exhaust, just on idle and when I rev it up when I stand still, I can’t see any smoke while riding if I look...

    Vmax 1200 -98 Misfires

    Hi! I bought this bike a month ago. Now when the weather is hotter and the engine gets warm it starts to misfire on idle and when I drive. It will also stall when I’m driving and stopping at a redlight, it always starts easy and I can drive further. I have removed the carbs and dissembled...
