Let’s dive in.

Common problems with Polaris RZR 800:

Air Filter Sucks Dust

Most of the people out there tend to change the factory air filter. Well, this air filter lets more air through but sucks more dust. This air filter doesn’t filter air very well. 

The air filter lets nasty and dusty air in the intake. As back wheels are rolling, airflow is dispersed on this place.

As a result, the top end of your 800 engine ruins. Your 800 engines will start showing problems, and you will feel overheating issues.

To protect your engine, you may end up using a top-end engine kit, cylinder walls, valve, etc.

I think users should change the Can-Am air filter and replace it with an OEM air filter. To do that, you can follow these steps –

  • Remove the lid of the airbox.
  • Remove the Can-Am air filter.
  • Clean the airbox.
  • Install OEM air filter.
  • Replace the airbox lid.

Rear Differential Pinion Nut Problem

This is one of the primary and common problems of razor 800.

This problem is caused by mainly using nylock nut (people sometimes say nylon nut) instead of using metal hardware in the nut.

The nylon nut comes off from the bolt after running overtime (maybe around 100 or 1000 miles) the nylon nut comes off from the bolt.

Boom! Your differential grenades will cost 1000 dollars to repair.

So, it is wise to use metal hardware pinion nuts to save your bank.

Power Steering Jump To The Left And Stop Working

Users are condemning Polaris power steering is jumping left at night.

They also feel this troubleshoot that power steering is not working or, if it works, turn to the left.

Low voltage is the main reason for your power steering jump to the left. Besides, power stop working when you use gas and brake pedal at the same time. 

You can use a switch to kill power to the power steering that will reset the power steering.

In the severe issues, you should conduct with the dealer immediately if you have a warranty.

Transmission popping out of gear in reverse

Transmission is popping out of gear in reverse is also a common problem.

A jerky acceleration occurs when you hit on the throttle, grinding sounds, failing to get gears are signs and symptoms of poor transmission.

You can either repair and replace it by taking consultation with experts. 

Brake Calipers Are Not Working

Calipers squeeze the brake pads so that wheel doesn’t spin. But calipers sometimes don’t work. 

If the brake pads wear out, wheel bearing becomes dry, caliper pistons overextended, the brake calipers will stick. Besides, deflated tires or misaligned wheels could be the causes of this issue. 

The sign of this issue is the wheel is dragging. You should conduct with a mechanic if you don’t know how to do it on your own.

Out of above all problems, users are commenting that they are facing the clutch problem.

Greasing the hardware would be the solution. However, you should conduct your dealer.

General Pros And Cons Of Polaris RZR 800

Polaris RZR 800 has 2008, 2009, 2010, 2011, 2012, 2013, 2014 models.

The earlier model had a 2-stroke engine, but the 2014 model has a 4-stroke engine. So, the power of the engine is great nowadays and has more horsepower. 

People could not ride the 2-stroke Razor 800 in muddy areas because of less horsepower. Climbing hill was also tough with the 2-stroke engine.

But now, you can ride on hilly spots and muddy regions with the 4-stroke Razor 800.

If you use gas, the engine works efficiently and produces more torque. So, you can get out of holes, gobbles up with incline, and drive through a wooden trail.
