Greetings. Here's the long and short 2007 VFR800 5100 miles. Has developed a misfire in the past week under light accelleration. When at idle she seems to idle fine but when i twist the throttle a small amount it chugs then takes off. No problem under heavy acceleration until i maintain a speed then i can feel a misfire again. I am new to VFR but have owned many honda's never experianced this condition. Thanks for helping !
