Hard shifting 2010 850XP Sportsman

I have a 2010 850XP EPS Sportsman that is very hard to shift through the gears while running. When it is not running it shifts nicely. I have read several threads here about adding washers behind the secondary bolt or taking shims out to stop the secondary from spinning while in park or neutral. My bolt and setup did not look like what was showed here on that specific thread. I took the belt off, and blew out the clutches, and reinstalled the belt. I guess everything looked fine. That was the first time I had been in there. Previous owner said the belt was recently changed. it did look good, and it is a Polaris belt. The secondary continues to spin while running, making the shifting very hard, almost two handed shifting. I have searched thoroughly before making my own thread. I’m sorry to those who have to hear about this issue again, Just looking for some help to make things like they should be and better. The bike has 402 hours and 2600 miles on it.
