About Polaris RZR 800

Polaris RZR 800 is an all-terrain vehicle (ATV) made by Polaris Industries, a manufacturer of recreational vehicles. It was first introduced in 2007 as a 2008 model. It is a four-wheel drive off-road vehicle with a four-stroke, twin-cylinder, gasoline engine.

It has a five-speed manual transmission and a top speed of over 60 miles per hour (mph). The RZR 800 is available in several different models, including the RZR S 800, RZR 800 XE, RZR 800 LE, and RZR 8004.

The RZR S 800 is the most popular model and is available in both two- and four-seat configurations. The RZR 800 XE is the top-of-the-line model and is only available in a four-seat configuration.

The RZR 800 was designed to be a recreational vehicle and not a race vehicle. However, it has been raced in several different off-road racing series, including the Best in the Desert series.

It has a larger engine than the other RZR models. This means that it is faster and has more power. The RZR 800 also has a wider stance than the other models. This gives it better stability and makes it easier to handle.

With an estimated dry weight of only 1,050 lbs., the Polaris RZR 800 is one of the lightest UTVs on the market. It is also one of the shortest with a wheelbase of only 50″. This gives the RZR 800 a tight turning radius which is great for maneuvering around tight trails.

Common Issues & Problems With Polaris RZR 800

1. Overheating

One of the most common issues people have with the Polaris RZR 800 is that it tends to overheat. This is especially common in the summer months when the temperatures are higher.

There are a few things that can cause the RZR 800 to overheat, such as the radiator being clogged, the water pump not working properly, or the thermostat being stuck closed. If you notice that your RZR 800 is overheating, you will want to take it to a mechanic to have it checked out.

2. Transmission

Another common issue with the RZR 800 is a transmission problem. This often manifests itself as a grinding sound coming from the transmission. The problem is usually caused by a faulty clutch, but it can also be caused by low transmission fluid levels.

You will notice the problem when you try to engage the clutch. The grinding sound will become more pronounced as you engage the clutch more.

To fix this problem, you will need to take your RZR to a qualified mechanic and have the clutch replaced. You may also need to add more transmission fluid to the system.

3. Front Suspension

Another problem that is common with the RZR 800 is a front suspension problem. This is often caused by worn-out shocks or springs. The problem can also be caused by a broken shock mount.

If your RZR 800 has a front suspension problem, you may notice that it doesn’t sit level, or that it doesn’t have as much ground clearance as it used to. You may also notice that the ride is rougher than it used to be.

In most cases, the problem can be fixed by replacing the shocks or springs. If the problem is caused by a broken shock mount, the entire front suspension will need to be replaced.

4. Engine Misfiring

It is common to experience an engine misfire in your RZR 800. This can be frustrating because you are unable to ride your vehicle. The engine may misfire for a variety of reasons. The most common reason is that the spark plugs are dirty or have become fouled with oil or other deposits.

Another common cause of engine misfires is a bad fuel injector. You should have your fuel injectors cleaned or replaced if they are dirty. The spark plug gap may also be too wide, preventing the spark from igniting the air/fuel mixture. The engine may also misfire if the ignition system is not functioning properly.

When this happens, you should check your spark plugs and wires. You may need to replace them if they are damaged.
