    96 Polaris 780 SLT Bogs at 3000RPM and will not accelerate

    The ski wasn't running when I purchased due to a bad stator. I ordered an aftermarket one from SBT on line and replaced it. Ran great for 10+ hours last season and this year, 10+ more hours running fine until all of a sudden, it stopped accelerating. It idles well up to 3000RPM then bogs out. There are no warnings on the MFD and the gauges are showing gas and oil. I pulled the grey wire anyway to see if it is operating in "limp" mode but it still won't accelerate, hot or cold. I fear it is the aftermarket stator. Help!

    Welcome

    Check cylinder compression.

    Thanks for the reply. The compression in all 3 is good - 125psi.
    I checked the stator and the blue/red to red/white checks 14 ohm, not 90 ohm as specified.
    The rest of the stator wires all check out fine.
    Does this explain why it idles up to ~3000rpm, but bogs down after?

    Its very possible. Bad stators can limit RPM. There have been more than a few stories of aftermarket stators not behaving properly.
