Got a 04 Sportsman 500 that wasnt running- owner said it needed a stater and a new battery. It ran rough (been sitting out in the weather for a while). A friend and I started by adding a new battery and it would start barely with the choke and his hand over the air-filter. I decided to install the new battery in the holder on the side. we had it on the rack because the old on was still in the bike. I tried to be nifty by turning the battery to put the terminals in an easier spot to get to, but forgot to reverse the cables too. In a sentence, I reversed the positive and negative on the battery like a dummy. When we discovered my mistake and corrected it, we turned on the bike, but the display did not light up and the key did not turn on the starter. jumping the solenoid worked the starter, so we thought the solenoid just burned up when I reversed the pos and neg... new solenoid and no difference. what have I burned up? Also, the shifter does not seem to do anything in the trans. it slides back and forth like its stripped in the trans. any help would be appreciated!!
I think the biggest issue right now is the electrical.

I have a 2017 Polaris Sportsman 570 EFI. Yesterday, I start the machine and it says low power (10.6-10.8). This machine is on its second battery. This is a new AGM battery with 50cca more than stock.
Should I look at the regulator or stator?
Hey guys, figure you guys would have some helpful direction or answers.
So, 05 Sportsman 700 carb, new carb, fuel pump, new plugs, new air filter, new everything I can think of that is usually the running issues. Starts up fine, seems to run fine, but if under load, two people, or even one person, up a hill, or pulling a drag chain for the driveway, it starts to cut out and sputters and loses all power, until I back off on the throttle and just barely try to let itself catch itself and then I can take off again.
I am going crazy trying to figure this thing out. Other than that, the quad runs great. Parents bought bran new, just used around the property, 5000 miles on it. Any ideas???

Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00. It's been sitting outside with no carburetor on it for about a year. Its rusty, missing some parts, wiring is all cut up and spliced etc. No seat, no racks but the plastic is all there minus the headlight housing. Anyway, who can pass up a $40.00 quad right? I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water. I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine. I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark. Did a quick compression test, 70 lbs. Wet test bumped it up to 90. Ok, so rings and cylinder washed out with water for a year, not too surprised. I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show it's got life. Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either. The compression is now around 60.
Anyway, my question is....is it worth it to try to get this thing going? I tore the top end down today and the cam and one of the rockers is pretty worn. I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well. Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again. Much less just to make it run and use as-is but I won't really like it until it's right. I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much. I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down? I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
I'll get some pictures today if anyone want to see them.

I am having an issue where it sounds like the gears are slipping if I hit the throttle really hard and also after letting off when the engine brake is applied. Also, the drive train that goes to the front also rides again the gear shift box. I will attach pictures and a video here shortly.
Thanks in advance!
Have a 2002 Polaris Sportsman 700 that only has 34mi. on a carb & ring job.
Cut the gas off today to drain carb.Now engine will not idle.If I open throttle will run,but let off & will cut off.Can screw idle in with no change.
What happened? Why did this happen when fuel ran out?
Please help me,my ATV is a daily driver.
