08 sportsman 500 Efi motor knock ? * Video *

I have an 08 Sportsman 500 that starts right up but motor knocks like this? It seems slightly louder when the machine is cold vs when it is warm, but when I get on the throttle and drive it it doesn’t seem to get any louder, if anything maybe quieter? Hard to tell. Check out the videos. Thanks! It has 4400 miles. First video Is cold start, and yes the motor killed at the end.. I didn’t shut it off, second driving, third, start when warm.

2000 magnum wont idle down

Hi I am new to this posting so please help if you can. I bought an new carb on amizon for my 2000 polaris magnum 325 4x4 i installed it on my bike now i can't get it to idle down. it revs up dies when i choke it. Any ideas what i have done wrong in the install??? bike ran fine before i change carb just it was leaking gas out the bottom so instead of rebuilding it i just bought new and installed thought it would be quick fix.
so any help would be great thanks in advance Kevin.

Hand warmers

The wires going into the hand grip broke off right at the grip for my hand warmers. I cant seem to get the grips off to rewire them. Are the grips glued on? Will I be cutting the grip off and buying new grips?
Its on a 2009 550 sportsman

LinQ 23 Gal Trunk Box (aluminum mount hook)

I found similar threads to this question but neither discuss the exact problem I'm inquiring about. If there is please let me know and I'll delete this one. I just bought the 23 LinQ 23 Gal (86L) Trunk Box for my 2017 Outlander XMR 1000. It came with two black hooks which I know are for the standard tubular utility rack, to mount at the back and help decrease the movement during riding. This obviously does not work with the XMR's LinQ rear rack as there are no tubular bars. However the box also comes with a small aluminum hook and a small black back mount plate. I am assuming this is for my model rack? If so, I can not figure out how/where it mounts. Does anyone have some pictures of how/where this installs? I will include a picture of what I'm talking about. Thanks for any help. Daron
