Polaris RZR Runs on One Cylinder | Polaris RZR 900S Dead Cylinder | Partzilla.com

We’re diagnosing a dead cylinder on our 2015 Polaris RZR 900S in this video from Partzilla.com.

We’ve done some work on this RZR before, and it’s been parked for a bit while we’ve worked on other projects. When we cranked it back up, it ran fine, then it would intermittently drop a cylinder, and then the cylinder died.

In this video, John will work through what might be causing the problem. We’ll look at the spark plugs, then briefly detour so we can replace the air filter on our RZR 900, and then take a look at the fuel injectors.

With the problem identified, John will show you how to clean or replace the fuel injectors on the RZR 900S and then we’ll get everything back together and test it out.
