XMR shock upgrade – what fits?

So I am running into an issue with trying to upgrade the shocks on my 2015 800 XMR. I called the local shop to see what options they had, was met with we'll research and get back to you. I tried Elka, but they have no product testing on my specific model.

I am trying to figure out if the 2016 850 XMR shocks will work on my bike, as Elka does sell Stage 3 for that model.

Also, looking to see what, if any, other options are out there. As you know, they stock shocks are garbage, any help will be appreciated.

Rear brakes will not bleed

So I picked up a used 2007 Can-am 500 outlander. Everything worked until....
I wanted to flush out the brake lines and get new fluid in there(old fluid was real nasty looking) . Did this by bleeding. So fronts bled fine, rear master brake cylinder bled fine went to do the back caliper and it wouldn't bleed. All the brakes worked fine. Now the front works but nothing in the back. I can't get any fluid to come out when trying to bleed the rear one. I checked line for blockage... It's all good. What could it be

Broken Dipstick .. Help

2015 Sportsman XP1000
Well... What the Hell... Let me start .. I was getting ready to change my oil this Pass weekend.. So I unscrewed the dipstick wiped it off.. and got sidetracked .. came back started it up and when I cranked it up my dipstick blew out .. smh.. So I put it back in. Let her run for a couple minutes. Changed the oil and filter, fill it up ... grab the dipstick and notice that a piece of it was missing.. Looking around I find it, inside the hole where the dipstick and oil goes ... mo#$@ f%$@^* What would happen if I would leave the piece there... I haven't turned it over to start it up. I've tried to pull it but it's a small opening the size of a dime .. I'm guessing next a vacuum... I don't know ahhh...
