I have a Polaris scrambler 500 I have rode this four wheeler for years haven't had that many bad problems. Right now I have a problem when I am just putting around and then give it full throttle it is bogging out and will just start to slow down and then once it slows down it will run but only with a little throttle I can't put the throttle all the way down or it will just bogg out again I have no idea what is causing this can any one help

 

Might help on knowing the year model,plus other things like has it been sitting up?,have you cleaned/installed a new carb kit,plus the basics like is the air filter clean,changed plug?
