Polaris Sportsman 500 Problems – Any Serious Common Issues?

The Polaris Sportsman range offers a wide selection of popular all-terrain vehicles and one of its popular models is the 500 series. The Polaris Sportsman 500 is known for its durability, power, and off-road capabilities. But even the best machines can experience problems from time to time.

In this article, we're going to take a look at some of the most common Polaris Sportsman 500 problems. We will dive in on the possible causes of the issues, and we will also include the most likely ways for your mechanic to fix them just to give you an idea of the amount of work required to fix your ATV.

Common Issues Experienced by Owners of the Polaris Sportsman 500

To find out the most common issues experienced by the owners of the Polaris Sportsman 500, we have gone over several reviews and reports published about the product. Likewise, we made some personal inquiries with some people we know who own it and mechanics who have vast experience working with it.

The problems range from the engine, drivetrain, transmission, and electrical issues. Some are more serious than others but it should be noted that even the most trivial ones here tend to blow out of proportion if not addressed in a timely manner.

With that, here are the most common problems found in the Polaris Sportsman 500 based on our research:

1. Struggling When Accelerating

If your Polaris Sportsman 500 is struggling when accelerating, it's important to diagnose the cause of the problem and explore possible solutions.

One potential cause of acceleration problems is a dirty or clogged air filter. A dirty air filter can restrict airflow to the engine, causing it to run lean and struggle when accelerating.

Another potential cause of acceleration problems is a weak or failing spark plug. A weak spark plug can cause misfires and loss of power, making it difficult to accelerate. If you're having trouble accelerating your Polaris Sportsman 500, check the air filter and spark plug first.

If those don't seem to be the problem, there are a few other things you can check. Start by making sure that there's enough fuel reaching the engine. If the fuel filter is clogged, it could be restricting fuel flow and causing performance problems. Check the level and quality of the fuel in the tank and oil as well. Low fluids can be remedied by simply pouring more of them until you reach the recommended level while dirty fluids should be drained and replenished with a fresh batch.

Next, check the ignition coil, wires, and spark plugs to make sure they're all in good condition. A weak ignition system can cause misfires and loss of power.

After that, examine the exhaust system of your ride. A restricted exhaust can cause backpressure that robs power from the engine. Make sure that nothing is blocking the exhaust path from the engine to the tailpipe.

Experiencing any of these are signs that it's time to take your Polaris Sportsman 500 to a qualified repair shop for further diagnosis. They will be able to pinpoint the exact cause of the problem and get your ATV running properly again. Dirty parts can still be saved with proper cleaning, if applicable, but worn parts will surely need a replacement right away.

2. Not Starting

If your Polaris Sportsman 500 is having trouble starting, there are a few things you can do to diagnose the cause of the problem and find possible solutions. First, check the battery to make sure it has enough power. If the battery is dead, try charging it or replacing it with a new one.

Next, inspect the spark plugs to see if they need to be replaced. Dirty or faulty spark plugs can prevent the engine from starting.

Finally, check the fuel system to make sure there is enough gas in the tank and that the fuel line is not clogged. A clogged fuel line can prevent gas from reaching the engine. While you're at it have the other fluids in your ride checked, too.

Replacing the battery is an easy job that you can do yourself. Most of the time, the labor for battery replacement already comes for free when buying a new battery straight from the shop. The other two entail more work and thorough diagnosis to really zero in on the root of the problem. Therefore, the smartest course of action for the latter is to bring your auto to a mechanic immediately for checking and repairs.

3. Transmission Slipping

When transmission slips, the engine RPMs increase while the vehicle speed remains constant or decreases. This can cause the driver to lose control of the vehicle, and can also damage the transmission.

If you're experiencing transmission slippage on your Polaris Sportsman 500, there are a few things you can do to diagnose the problem. First, check the oil level and quality in the transmission. If it's low or dirty, topping it off or changing it may solve the problem.

If the transmission fluid looks clean and full, the next step is to check the clutch. The clutch could be slipping if it's worn out or needs adjustment.

If neither of those solutions fixes the problem, there's likely an issue with the transmission itself. This could be something as simple as a loose bolt or damaged gasket, or it could be a more serious issue like a cracked gear. Regardless of the cause, it's best to take your ATV to a qualified mechanic for repair.

4. Shaky and Noisy When Idling

If you're noticing that your Polaris Sportsman 500 is shaking and making noise when idling, there are a few potential causes. It could be an issue with the engine, the drivetrain, or even the tires.

To diagnose the problem, start by checking the engine for any loose or damaged parts. Then, check the drivetrain for any worn or damaged components. Finally, inspect the tires to see if they're properly inflated and don't have any excessive wear.

If you can't find the root cause of the problem, it's best to take your ATV to a qualified mechanic or dealership for further diagnosis. They'll be able to pinpoint the exact cause of the problem and recommend the best course of action to fix it.

One of the most likely fixes they will do to your ATV will involve adjusting its idle speed. If the engine is idling too low, it can cause shaking and noise. Simply turn the idle speed screw clockwise to raise the RPMs.

They may also check and adjust its drivetrain. If the drivetrain is out of alignment, it can cause vibration and noise.

Next, they may balance the tires. An imbalance in the tires can cause shaking and noise at lower speeds.

Lastly, they will have to replace any worn components in the aforementioned parts.

5. Lights Not Working

There are a few different potential causes for this. Sometimes, the problem can be as simple as bad bulbs. Inspect the bulbs and replace them if they appear to be burned out or damaged.

Another primary cause is a drained battery. However, if it still checks out well, proceed with the other key culprits.

One of the most common reasons for headlight failure is a blown fuse. Check the fuse box for a blown fuse and replace it if necessary.

Loose wiring can also trigger this. Inspect the wiring harness for any loose or damaged wires and repair or replace them as necessary.

If the headlight relay is faulty, it can prevent the lights from working. Check the relay and have it changed with a new one if needed.

The headlight switch may be the culprit, too. Inspect the switch and replace it if necessary.

These are just a few of the most common reasons for your ATV lights not working. Changing the fuse or lights can be done on a DIY basis, but to be sure, just take your ATV to a qualified technician for a more thorough diagnosis and repair. The real source of your ATV's electrical problems can be hard to pinpoint at times, so just have a professional do the job for you.
