Just got a 2013 MXU 500i. Only 90 miles, bought from dealer who sold it new. Having an issue with shifting between Reverse & Park. I shift from any gear, L/H/N into Reverse no problem, but R to P I have to rock the bike till it sync's in. Sometimes I have this problem from Park to Reverse but always R to P. I've seen several post relating to shifter issues, but none that sound specific to my issue. Otherwise the bike is solid. Not as smooth as my Grizzly but not as pricey either. Any ideas ?
