 Hey! If you're looking to repair your Polaris ATV, check out my channel and please subscribe. I've got plenty of Polaris repairs. More subscribers I get, the more videos I make and the more you get to learn. I got two strokes, four strokes, whatever you get, I got a video on it. Right now I'm working on the scrambler. Hit the like button if you like the video and I hope you enjoy the show. So is your Polaris backfiring? Well, I got the solution for you. I just installed this motor and I've got the same issue. I'm going to show you what to do and what to look for, how to fix the issue. But first I'm going to show you what this bad boy does. I'm going to fire it up and show you how it backfires and then I'm going to show you the solution. So I'm going to have to pull start this baby. So here's what we got going on. Something you want to keep in mind. Something wrong with my cable. If you look through here, you got your kill switch. When I grab the throttle, let go and it touches those two points. Another thing I got going on with this cable, this throttle cable is actually junk. I'm going to grab a flashlight here. If you can see down by the oiler, the oiler is stuck open. So when I pull the throttle, it doesn't want to close all the way. It should actually close even further. This cable has, I don't know, it's corrosion, rust, not allowing the carb to close all the way. So what I need to do is I need to replace that throttle cable. Because it's rusty, it's sticking, causing it to backfire, dumping too much gas into it. Like I said, other issues could be this kill switch that the slide on the carb is enclosing. It's allowing too much gas to get in. And this isn't functioning properly. I mean, it's actually kind of sticking. There is an adjustment right here to adjust your linkage, adjust your throttle. So you can make this tighter or looser. Yeah, this is not adjusted correctly at all. So if you've got an issue with your Polaris backfiring, this is probably most likely your problem. There is also a timing issue. You've got your CDI box, which is right here. So if you've got issues with your CDI box, that could be it. And if you remove this cover, your stator, there's a mark on the stator plate. And you turn that a little bit at just the timing. That could be another issue. But what I've got going on here is my throttle linkage, and that's messing everything up. So I hope this video helped you out, and thanks for watching.
