2016 850XMR minor issues

Bought a ’16 XMR 850 and really like it other than a few small things I’ve noticed over the past 2 rides. I’ve read a couple people have noticed the same things so I want to get out to a broader audience and see if it’s a bigger issue. Bike has 50hrs/300mi. Purchased from previous owner at 37hr/237mi.

– The valves are loud as hell. Much louder than my buddies 850XT.
– Will creep forward/backward while in gear, especially during a cold start
– Shifter is fairly hard to move and sometimes will grind going in gear. Had it "jump" out of high gear one time at about 30mph also.
– Have heard belt squeal on 3-4 occasions while in low gear.

Linkage may need to be adjusted, valves tightened, clutch inspected. Previous owner could’ve glazed the belt badly and may be causing the squeal (after-all, it was his first Can-Am). Went to a dealership today just to compare other shifters and the ’16 Outlander I checked was stiff like my 850 but a ’16 XMR Renegade was like butter. Possibly the linkage design?

Has anyone else had similar issues?
