backfire

Suggestions on why it does on decelleration from the exhaust?
The last 2 rides. 1st ride was a small pop pop pop sound. 2nd short ride was loud bangs on full throttle to coast.
Last year i replaced the rubber boot from the carb to the engine and that solved it. Been good all year now till just a few days ago. The new boot is still crack free.
plugs arent that old but i found a loose top part of the plug that screws onto the plug....fuel filter is good. Maybe an exhaust donut?
Have been playing in alot of water, but the 2 rides have been on road and dry.
I'll pick up new plugs today.
Machine starts and idles great..lots of power too.

Loud bang with out the engine turning over

Good morning. I need some advice. My 2005 sportsman 400 won't start. I turned the key as to start it and with out the engine turning over I hear a loud bang. It sounded electrical especially since nothing from engine turned. If I pull start it, it will only start once and it will run for a few seconds and die. Then it wont pull start till many hours later and it will do the same, start and not run more than a Second or 2.
What's the possibility it could be the selonoid or related? Any advice would be a great help ty

castle nut torque value

Hi

I have a 2012 sportsman 550 EPS & I'm going to change the rear wheel bearings.

Can anyone tell me how many ft lbs to torque the castle nut too?

I found some you tube videos but they all had different torque specs & none of the videos were for my specific model.

Thanks in advance

2008 800 Front Differential Issue

Any help or opinions are greatly appreciated, I have a 2008 Sportsman 800 with 1200 miles of light use, I have owned since new. Due to a 4wd problem (constantly locked in) I took out my front differential hoping to find the common blown up sprague cage, well that I did not. Every thing appears to be in great condition and intact other than when I took out the output pistons and parts on the drivers side I found wrapped around the output pistons was a bunch of black plastic material. It appears the piston was rubbing against the black plastic ring section (see pic 1 zoom in) that comes as part of the case on both sides. I assume it is some type of a coil or something? Not sure if this is supposed to be ever touching or not. It almost seems like in a manual transmission you have the flywheel and pressure plate that might be slipping causing it to melt off instead of making full contact? Just not sure how these 2 parts are supposed to mate or not touch at all. I assume the 4wd is locked in because of the mess that I found(see pic 3). If you look at the second pic(zoom in) I also have 2 pretty good grooves worn in the armature piece not sure if this is supposed to happen either? I posted a few pics first should show the wear/melting on the whatever its called, second shows the mess on the workbench and third shows the melted pieces that are from the first pic. The passenger side does also have some wear on it but no real debris. Thanks to all who can help and hope I put this in the right section. If not please advise.

2015 850 cuts out when throttled

Just bought a 2015 850. Ran great first day but when I started out the next day the engine began hesitating when I throttled. Played around with it for half an hour and it ran great the rest of the day. Two days later I hopped on and it did the same thing. It idles fine, but when I give it gas it dies. I try to keep out of heat but it didn't help

Is this bent?

I am working on a Xpedition 425 as the parts arrive in the mail. Today I received u-joints and while removing the old ones I noticed the propshaft yokes do not line up which makes me think the shaft is tweaked. It looks straight just by eyeballing it, but is this normal for a Polaris propshaft? I appreciate any help.
