    2013 250 optimax pro xs cutting out

    #1b974279 Everything on my motor is running fine but when I get running it hard it misses every now and then. Usually it's just when I get above 5k rpms it might miss every now and then, sometimes it might be every 30 secs or so and sometimes every couple mins. It has done it at lower rpms but rarely. Any thoughts what might cause that?

    While there are a number of potential causes, it's best to start with some BASICS, and a review of ANNUAL Maintenance.

    Items such as Spark Plugs or Plug Wires are some of the most COMMON items to cause this type of performance problem.

    Review the following list, and ensure that ALL recommended ANNUAL Maintenance has been performed:
