I got a 2010 rmk 800 with 4400 miles on it. sled runs awesome until you get into 55-65 mph range. it has 125 psi of compression on both cylinders. i just rebuilt both sides of exhaust valves. when riding all weekend and it cuts out in the speed range. im pretty positive that the updates have been done to it. you hold that throttle at a steady speed. and it cuts out and comes back into it. no check engine lights or nothing. anything 3/4 throttle or more its fine.

Everything is stock on this sled. its only in the mid range is when it happens
7000 RPM is were the exhaust valves are supposed to open so check them. Your TPS might have dead spot in it causing this problem. Previous post about hitting rev limit might be a problem too.

I ended up puting in 2013 exhaust valve springs in it and it took care of it. i also installed a fuel commander and its runngin awesome now.
