Sputtering problem

[fatboyslim]

I was out just putting around my yard with my bike today and I had the throttle wide open and the bike started sputtering bad at high rpm. It kept on getting worse and worse as I kept riding. Could this be water under my stator cover cuz i just pressure washed it. Or bad spark plug? Plus my clutch seems to be slipping more now when I am at a stand still holding it in. Any ideas?

do you mean it's missing? if you do it could be a fowled plug. might wanna take out the spark plug and clean it or change it.
