If the rings are below that nick at TDC then it'll be fine. If the rings go over that though I'd bet it would ruin a ring. Looks awesome otherwise, good work.

Agreed, not bad at all. @MarkinAR smacks it right on the head every time!!! Its not as bad as it seems. If the rings aren't flying up that high then my guess is the rings will settle in fine and be good.

I have never had any luck with cylinders. I always end up with a scoring or nick right by the exhaust port or the rings break and gouge something. Mine always end up needing to be bored or replaced. I have bad luck though. I hope you are luckier than me. 🤞

Well cleaning it up a bit more and it almost gone and should be good to go with new piston and rings now to get them and the gaskets and put back together and run it 

First 2 stoke atv I ever rebuilt , I usually just stick to heavy diesel ..lol

@bren7176 Thats good news on the cylinder.  Make sure you get quality gaskets. It will come back to bite you in the ass of you dont.   

@Jennifer Schuler we all have our one item that we have bad luck with! Mine is usually pocking up atvs that always wind up needing a stator coil.

I bought a middle of the road gasket kit on the last rebuild and the head gasket blew and orings crushed. Buy OEM on partzilla, it's about $20 difference and you won't be pulling it apart again in 2 weeks.

      Has anyone found a good replacement for the stock cooling fan? Mine is going out and OEM parts are outrageous. Polaris sportsman HO XP 850

      Had a spark-plug break off, had to pull the head to get it extracted. Where the heck is the timing mark on the crank? Do I need to pull the stator or flywheel to find it? When I pulled the head I had the mark on the cam lined up pretty good but I cant remember if it was perfect and don't want to reassemble a tooth off and have to go back through the bear of pulling this thing back apart.
      Thanks guys!

      After purchasing a lightly used 2018 570SP (300 miles on it) I noticed that the display was flashing on and off. I remember reading awhile back that this was a common problem on the 18 model. I can't remember what the fix is. It also turns over slow even though the battery is charged. Anybody know what the fix is on this issue?

      I just rebuilt my 03 sportsman 400. Put everything back together added oil per the manual. Pinched off the oil tank vent line 2" away ran for 45 seconds then cut it off. Check oil level and it was still way high so I wasn't confident that it primed so I did it again. Checked again and it's the same. Remove the oil filter and it is dry. I did the procedure again and the same results.

      I'm worried to keep trying this as the only oil in the engine is what I used to lubricate the parts when reassembling the piston. The crankcase was drained as well.
      I Removed the oil tank and checked all the lines for obstructions and the screen filter and the vent hose and everything is clear. I even pulled a small vacuum on the oil tank while it was pulled off to make sure there were no leaks. The dipstick cap was on tight so I'm not sure why this thing is not priming.

      Anyone have any suggestions. I thought about pre-priming the oil lines from the oil tank to the crankcase to hopefully help the system prime. I'd like to be able to add some oil to the crankcase to so I wouldn't feel so bad about running the engine for another 60 seconds without oil. I dropped just a little bit of oil in the spark plug hole to help condition the sleeve right now.

      What do I do? Anyone had or heard of an oil pump failure on these. Btw oil pump is working fine before I did the top-end rebuild and the oil pump was not touched.

      Please help!!! Thanks all for any and all help.

      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)
