Old summit I had did that shortly before the motor went, I would definitely check compression and scope your rings. If it's hard starting I would definitely do some hard lookin
2012 RMK 800 dies when put in reverse

Had an 06 600 rmk that did this just before the motor seized up. Crank bearing went out.
compression
Could be your gauge reading low but that is low for that elevation in my opinion i would pull it apart and have a look. Way cheaper in the end then after it blows up.

107 may be a little low, most likely the gauge, the key is that they are reading the same so likely your pistons are good!!
compression
Mine read 155 psi at 3400 ft with a 13.6-1 head and the pistons had .009 clearance i wouldnt call that good. For the price of the gaskets I would have a look.

Had plugged filter on truck cause this. When was the last time the fuel filter was changed?
Absolutely. Recommeded intervals are once a year or 1,000 miles.
Have you checked your throttle cable for excessive slack yet?
I live at 3800 ft and the only "stock" 800 poo engine that I have owned that had compression over 112 was the 08 Dragon and it was a whopping 115. Both 09 Dragons, and 11 Assault did not break 112. I have a 2013 that I will have to check and see if they are any higher...
compression
Stock with 400 miles my had 125
with 13.6-1 PA head it had 155 with 850 miles and .009 piston to cylinder clearance.
MTNTK top end and 13.6-1 head it now has 170
The same gauge was used for all readings not saying the gauge cant be reading high, but it reads the same as the Snap on one from work. Aslo long as you use the same gauge all the time it gives you a base line to work with as the miles add up.
