Polaris 120 surging ?

[DalensM8]

I have a Polaris 120 2009, what is causing it to surge at idle? It runs perfectly fine, but sitting at idle the engine will surge up and down?

Try unhooking the blue wire by the votage regulator. Is on the right side down by the footweel.

did you check to see if the govener is causing it?

LOWER the idle speed !!

sounds a little weird, but just try it, I had the same problem with my daughter's 2008 120
