I picked up a basically new '22 850 PRO from a gent who only rode it one time(38 miles). Took is out yesterday to put some break-in miles on it with a riding buddy. We rode the same distance. His Ski Doo showed 39.9 on his odo, his GPS showed 40.1 and my odometer showed 46.5 miles or 6.5 miles more than the distance we rode. I've never had a sled(over 25 owned) show that big of a discrepancy. Has anyone else had an issue with an optimistic odometer? Another Poo riding buddy spoke to his dealer and they thought that a reflash would not help and suggested I contact Polaris Cust. Service and see what they say. Appreciate any comments.
