Polaris Sportsman 09 XP550 EFI idling way high September 8, 2015 All of a sudden my quad is idling way high (like 1820). Seems to me it used to be around 1200. Is there a simple fix or do I need to take it to a dealer? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
