poor perfomance and exceleration need help

[texanwake]

i have a 2008 see doo challenger. we jst got it last summer in july and used it almost every weekend and never had a problem with it. it was running great right before we had it winterized for the winter. when we pulled it back out for the first time this year it had a lack of accleration, top speed and overall performance. we have already changed the plugs and gaps are set to the correct spacing does anyone know what else the problem could be? i believe it only has 30 - 40 hours on engine.

When it was winterized did they put an additive/preserver with the fuel?

Sounds like your fuel may have gone off, I have had the same problem with one of my bikes before, the old fuel was removed & new fuel was added and it ran fine.

I have also read that in addition to the fuel additive, the fuel tank should be left full otherwise you can get moisture in the tank over time & water and fuel dont mix.
