When my p650 warms up in the winter it will sometimes make a sucking in air sound from the air box area. It only does this when she is cold. I would think its normal for this quad but it might not be because my V-Force does the same thing but alot more. My v-force will do it warming up in the summer and winter, but once its warm it rarely does it anymore on the V-Force. One the Praire once its warmed up I have never heard it do it again. I only experienced it on my V-Force after I slapped on the duals.

Does anyone have any recommendations? Could my jetting be to rich so its fighting for more air? Are my carbs not set right? My V-Force is at a mechanic right now getting my insurance claim processed. Is there anything I can ask him to look at? Thanks for the help guys.

 

100% normal.

 

Hmmm....weird. I'm glad its normal, I wonder if it has something to do with the CDI retarding the motor? I wonder if the CDI and advanced timing will cure this air sucking sound?
