    ultra 250 wont go faster then 29 mph

    my buddy has an 07 ultra 250 and ran fine last year on the lake and the year before that when he bought. it has worked fine so far this year but last weekend we went up to the lake and went to start it up and go ride and it wouldnt go faster then 29mph. so we took it to the dealership and they said they would call when it was ready. they called later that day said it was ready and charged him $130 to put 4 new spark plugs in and said it would work like new. so we went and got it went to the lake this weekend started it up and it wouldnt go faster then 30mph. is there anything to check for before we take it back up and him spend an arm and leg for it?

    Maybe a stupid question, but is that 30 mph measured from the ski's speedometer, or from a GPS?

    Is it possible the speed sensor at the back of the ski got tweaked and is only reading 30 mph when the ski is actually going 60 plus mph? You guys know how accurate these things are.

    buddy took it the the dealership before i could tell him and they said it was the hose. so thanks it helped but didnt get to it fast enough but thanks still
