Damn water holes

Hello guys and gal. So I just picked up a new 2018 570 x2. Used it hunting and put 60km on it during that hunt. Today I went out and ended up going into a waterhole and sunk the bike up to the seat. Engine was running and I got stuck in the hole then the engine died. I got it out and towed back home.
Pulled the plug and shot a water out. Checked the oil and it looks brand new. Now the plug was still giving some spark but it doesn’t look that great. So I’m thinking a new plug and change the oil. Do I need to do the tranny and both diffs as well??? Air box was dry, and I’m pretty sure that the water came into the engine through the exhaust.
What should I do ?
Thanks guys for the help

Scrambler 1000xp

I just picked up a 2016 1000xp with 167 miles on it. Traded a 89 quadzilla even for it. So far $2,300 into this scrambler.

The previous owner swamped it and it was hydrolocked. What he told me was he towed it back to his house drained it and changed the oil 4 times total and had it running “good” then it seized up.... I got it home and pulled the starter and turned the flywheel and it’s Not seized. Starter wasn’t engaging so I put a new starter in and it started and stalled and wouldn’t stay running. Changed the plugs and turned it over for a while with fuel pump unplugged and plugs out. Put the plugs back in and it started and idled fine but high (1250 rpms) let it idle for 30 minutes or so and then took it across the lawn and seems very under powered. Compression test is 90PSI both cylinders. Thoughts?
Bent valves? Jumped time?
Previous owner never disassembled anything on the motor..

Need help!

Predator 500 help please

I have a 2007 predator 500. I have owned it for 4 days. Ran great when I got it. First day I took it on about a 3 hour ride. Didn’t ride it hard and had no issues. Same the second day. Third day I checked all the fluids and everything looked good so I went on a ride. After an hour of riding. I heard what sounded like valve noise. I headed home with the quad. Got about a mile from home and the noise got really loud so I stopped and walked to get my truck and loaded it up. Then today unloaded it and started it and it smoked black and white smoke like crazy. I checked valve clearances and they had quite a bit too much clearance. Pulled the cams out and the decompression piece on the exhaust cam is really loose and doesn’t move smoothly. I need help on where to start. Please help.

Slip on exhaust

stator output specs

Buddy of mine is having some electrical problems and has been throwing parts at the bike I'm trying to help him figure out if his stator is bad. Bike is 2015 Sportsman 850 with bike at idle I tested all three wires in the stator plug ac output and got 19,19,20 I heard spec was 22-30. Does this mean he has a dead leg in the stator or is that close enough to be right

Differences between a 2011 & 12 Sportsman HO 500 (carb)?

Are there any differences between a 2011 & 12 Sportsman 500 HO (carb) model years?

I bought a 2011 where I'm hearing Polaris redesigned and went back to the carbed from efi (to save money?). I found a pdf of the Polaris 2012 mechanic's Service Repair Manual that will be used for reference; an differences in models to the 2011 Service Manual?
