    2008 Ultra 250x Low Rev. would stall when you accelerate! Help!!

    Took the ski for a weekend after replacing super charger clutch and its bearings and belt, was working great but at the end of the day it failed, unfortunately I was not riding it while it happened, I lend it to a friend and his kids, he came back very slow, when I jumped in to check the ski would not go more than 2000 rev when I accelerate it dies but will start again! Not sure what it is! No codes!!

    best guess.

    he was doing a bunch of doughnuts, starved the jetpump and overheated the engine. bores are warped and dragging on the pistons

    do a compression check before you end up needing to replace the block

    how the oil look..engine was more then rattly

    check the airhorn on the front of the airbox and see if its loose
    the rattle noise is typical / normal of those models
