 Alright, so this video is for you guys that love those two strokes, I picked this thing up and head gasket was blown. I'm going to tear this down, take the hat off, show you guys how to do that and uh yeah we're we're going to town and this thing this thing is getting stripped way down so I have a seat, sit back and enjoy the show. Alright so the first thing I like to do whenever I'm checking out a motor is pull a spark plug, because the spark plug that's going to tell you everything. It tells you how it burns, tells you if there's any fuel in there. We're going to take a look at this. I think the funny feeling is probably coolant in there. You can see that, it's wet, there's oil in there, you can smell it, smell if there's any fuel, it just looks a little like oil. Also shine the light down the cylinder, it's wet, that's good, it's a good sign that there's no coolant in there. So what I'm going to do, I already got the carburetor off, is I'm just going to pull the jug off from the bottom of the base. I'm going to pull them four nuts off, slide the whole thing out and I'm going to test it with the head on to see if the head is what's actually leaking. That I want to find out and I'll be able to get a glimpse of the piston right away. So that'll be next. So what I'm going to do, and it's in tight quarters so you're not going to be able to see it with the camera, is I'm going to take the ground strap off, these bolts off, that mounting bracket off, take my carb boot off, and don't forget to unscrew your oil injector which is right here at 10mm bolt that'll come off. Loosen my hose clamps, take those four nuts off around the perimeter and my upper hose, and I'm going to slide that right up. When I get to that point, I'll start videotaping again, but this is something I can't really videotape because my hands will just be in the way, so thought I'd show you what I'm going to do and show you my next step after. All right, so the jug's all ready to pull. I got the four nuts off of there, got everything disconnected. I got my hoses disconnected. Now let's see what we got. When you do this, try not to bust this thing off for your temperature sensor. Let's straight up, bro. The cylinder looks good. No issues there. My next test is, I want to see if there's any coolant in the bottom of the engine. Let's see, a lot of fuel and oil. So I'm wondering if it wasn't a coolant issue. I'm wondering if the gas was flooding into the engine. So I'm going to take a closer look. The camera's not really showing anything, but kind of see what's going on. The piston's got a little scoring on it, but not bad. It's still usable. I'm going to take a closer peek and let you guys know what I find out. All right, so I'm going to show you one little test I did. Put a hose clamp. Just kind of cut this off. Put a hose on it. Just clamp the hose in half to see if the drain's out. I grabbed my bucket down here with the coolant in it, and I put it in this spout right here. The head is upside down, and I have coolant flowing through the jug right now. If you look at the base, there is not one single drop of coolant. So that tells me that that wasn't the issue. It's not leaking. So either I got a radiator issue that it was overheating and spitting out the little puke tank hole because I got a crack in mine somewhere leaking out somewhere. This went overheated. Oh, here it is. Here's the crack. Shout out that crack. And I didn't have any coolant left in the radiator. So I thought it dumped into the engine. So looks like I might be replacing that radiator. But so far what I can see, you can see this coolant in here. It's all the way through the jug. Not a drop at the bottom. It means that's sealing good. So that means I did it correctly. So I'll throw the jug back on and try firing it up and see what happens. All right, so now I inspected the jug and the piston. Everything looks good. So now I'm going to put the jug back on the engine. Put a new gasket on. Now when you put the jug back on your piston rings, your pistons have little stoppers in here and here for your rings so they don't move around. So you want to make sure that they are lined up. Otherwise you'll destroy your jug. So when you put the jug back on, you squeeze these back in. Make sure it's lined up. Do both. And then slide the jug on. So they make a piston ring squeezer that you can buy, but I can do this by hand. I'll show you how I do it. So I put a little oil inside the the jug just to make the slide on a little better. It's so much easier with all the other stuff in the way. Let's slide down. Get your holes ready. Get my exhaust spring stuck in the way here. Your holes are pushing the head down. I got a little bit of a trick and I can put my nuts back on. So this one down here is a bit of a trick and you want to tighten them down in a crisscross pattern. So what I do for this one down here, because it's such tight quarters, I've got extension with a beveled edge and this thing actually will rock on it. Put that on and I can get in there and tighten it. So I'm on this one. Give her a couple good wraps. She's tight. I'll go ahead and hook up my oil injector and my hoses and then I'm going to clean the carb. I had a five-month-old gas in this thing. I don't know if you can see it in the camera, but it's already crusty along here. Just five months. I'm just kind of shocked how crusty and crappy everything got. So I guess don't use gasoline with ethanol in it. If you do, make sure you put stable on the gas, which I didn't do. So I'm going to start using premium gas with no ethanol in it, and that'll probably save the headache of having to tear this apart. All right, so I'm going to put the carb boot back on. Put this guy back in. Make sure you put your ground strap on when you put your motor mount on, or it won't run correctly. It's the ground for everything. I've actually bought in ATVs that the guy couldn't figure out why it ran like crap, and here the ground strap was broken. That was putting a ground strap on and fired up. She's good to go. Little things like that get overlooked every day. If you don't know what you're looking for, let's install. I'm going to hook up my oil injector line. 10mm. Definitely don't want to forget that, or you're not going to have any oil. Make sure it's cleaned up. Don't forget your little temperature sensor. Something that gets hooked up here. That'll tell your fan to go on. Those go bad, so I might want to consider replacing that if fan's not working. I'm just going to hook up my hose here. Clean the carb, and then I'll go fire it up. Okay, so one thing I forgot to mention while I'm filling up the radiator is there's a air bleeder screw on top of the head. 10mm. So I'm going to fill it up with coolant. Listen for the air to rush out. Wait for a little coolant to come out of here. Once it starts coming out, I'm going to tighten it up, and then all the air will be out. I'll start filling it up to see what happens. I forgot my bottom hose. Like I said, don't forget your bottom hose right here. I missed that. Kind of in a hurry trying to show you guys what to do here. Hurry, that's when you screw things up. If you can hear the air rushing out, it's starting to dribble up. I'm going to tighten that up. Now if you forget to do that, you're going to have overheating issues because you've got air trapped in your coolant lines. There we go. I've got everything all back together. My battery's dead, so I've got to pull start it. So I'm going to take a couple cranks to get this thing to fire up, and we'll see how it does. All right, so let's give her a shot. Got her all back together. My battery's dead, so I've got to jump her cables, go into the battery, fire it up, and see what happens. Before, when you heard me start up the engine, I don't know if you heard something rattling around. Oh, look at that. So the recoil broke, and this little lever that connects onto here broke off, and I also cracked the pan. So it's not like it was in the engine, but here was just the full start cover. So this thing's shot. You can see it's broken. I don't know if you can see that in the camera. So it's not the engine that's bad, it's this. So until I get one, right now I'm just going to put it back together because it's winter in Wisconsin, and I need this thing for plowing. So I sold my last one already. So there's the issue. So you ever hear any rattling around in your engine? Don't think it's necessarily the piston. Could be your recoil, it could be whatever this will flop around in your flywheel, and that's it. Today I got my helper, my son. He wanted to help out with the four-wheel, which I think is awesome. He's seven years old. Smile all the way to the camera, Logan. All right, go ahead. He wants to finish putting the cover back on. See, this is so easy. Even a seven-year-old can do it. Little bit more on that one, buddy. I think it's a little off. Okay, you want to start on them up first, make sure you're all the way on, and then hit the trigger. There you go. Good. I'll do the next one. There you go. Perfect. And one last one, I think, and we're not on yet. There, go ahead, give her. Perfect. And there you have it, the recoil cover up. All right, so I got her all back together. Tune the carb. I'll show you how she runs. Here you are. I just got to put the clutch on, and she's ready to go. It's all back together. All right, I said transmission, top end inspection, new swing arm, tighten the chain. Just got to re-upholster the seat. That's what I'm waiting on for the rest, and she's going to be ready to go. So I hope you enjoyed this video. Subscribe to my channel. I have tons of Polaris repairs on there, and I hope you enjoyed the show. Thanks for watching.
