I have a 2011 850 Sportsman. Has been absolutely trouble free except for 1 thing. I am on my 4th. ignition switch. I don't know if it's that they are all chinese junk or what. It gets to a point when you turn the key and it will act like the battery is going bad. Cranks real slow or not at all. Put a new switch in and its fine. New one will last 1 1/2 - 2 years and its junk. I've had the Polaris brand and after market. As a matter of fact the original one lasted the lest amount of time. Other than that it's been a perfect machine . No electrical problems. No battery problems. Just curious if anyone else has had the same issue.
