    Viper Timing Gear

    Some have said it could be caused by a backfire? I know with the old flash I had a few good backfires at start up and after good full pulls.

    New Ecu flash for Yamaha Viper/Arctic cats 7000 w/POLL

    If it has jumped out like mine was, the timing is off and likely over fueling and hard start when hot. You can pull primary, cover, etc and look to see if the alignment marks are out. I think that most of the problems people are having with new flash ( that are stock) are related to this issue.

    Viper Timing Gear

    I would only have to give it throttle at start up. Then it would idle fine and run normal.

    Viper Timing Gear

    My dealer changed mine because of starting issues after new flash and it is now working great. Mine was out 1 tooth. Always ran great once started. If I gave mine a little throttle it would lean it out and fire every time

    Try giving the 14 a touch of throttle on hot start when it cranks longer than normal and I bet it fires. My dealer has been trying to sort this out for s month. Tommorrow he is taking off primary to see if the stub in the crank is in the correct position?? This is what Cat has asked him to do?
