Charging issue?
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?
Thanks!!!

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.

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???

Trying to figure motor size, says nothing on plastics, or the title, only numbers are EC25PFX 01 Which
are on the cylinder. The vin code is 4XAAG25C312459874
Tried vin search but still doesn't show motor size.

In this video, Jonathan describes how he cleaned a Nikasil plated cylinder.
Aluminum cylinders are often coated with a harder material such as Nikasil (Nickel Silicon Carbide). Over time, the softer aluminum of the pistons can rub off onto the cylinder. When rebuilding the top-end, this should be cleaned off.
This can be done using hydrochloric acid which reacts with aluminum to produce hydrogen gas and aluminum chloride, which washed off with water. Since Nikasil is resistant to corrosion, it is undamaged and protects the cylinder during this process.
Here is the chemical reaction:
2 Al (s) + 6 HCl (aq) → 2 AlCl3 (aq) + 3 H2 (g)
