    2003 gp 1300 backfiring/bogging

    I newly rebuilt the motor and I'm having backfiring issues with my ski.
    It Boggs from WOT to idle when I gun the throttle and backfires. But it will rev fine if I ease into the
    throttle. I have also blown the rear seal. Just added a d plate and air filter.

    Sounds like a timing issue, and improper timing will blow the seals.
