636 wont rev

  1. Mechanical and Technical
    having issues with my 636....replaced plugs /coils/ecu and when bike is accelerating around 10k it just stumbles and wont rev any higher..thought it was my coils since i had just replaced the plugs prior to a trackday. been replacing parts and cant figure it out. no backfire or anything,,,always...
