1999 Polaris Sportsman 500 Problems
In 1999, Polaris released the Sportsman 500 as a successor to the Sportsman 400. The new model was designed with updated features, including an all-new engine and chassis. However, reports soon surfaced of various problems with the vehicle.
Problem 1: System Overheating
Riding the ATV in high gear for an extended period can cause piston seizure. This can happen due to a lack of lubrication and dirt build-up.
This overheats the engine, especially when riding on very hot days. Too low an oil level can also lead to piston seizure and overheating.
Symptom: Burning Smell
When the ATV rider’s internal system is overheating, a burning smell will often be present. The fumes can be quite intense and cause headaches or nausea if inhaled.
In addition, it produces black smoke from the exhaust, meaning a problem with the engine.
Solution: Cool Down The System
Stop the engine immediately and allow some time to cool down. Then, remove the spark plugs and spray water into each cylinder. Crank the engine over several times to distribute the water.
Also, you can replace the spark plugs if it is blown and try to start the engine. To do the job, you must do these things:
- Gather all the tools you need, such as screwdrivers, pliers, and wrenches
- Unscrew the spark plug by removing the coil and the wire.
- After that, place the new spark plug down and screw it into the system with the wire and coil.
Furthermore, to resolve piston seizure, the engine must be taken apart and the piston replaced with a new one. Additionally, regular engine tune-up and oil changes can help prevent piston seizure.
Problem 2: Cam Wear Issues
There are a few things that can cause a camshaft to wear out inside an ATV rider. One of the most common reasons is that the camshaft becomes misaligned.
When there is too much slack in the chain or belt, it causes the camshaft to move out of position. It can rub against the valves and wear them down over time if it becomes misaligned. Too much friction can also cause camshaft wear as they are made of thin metals.
Symptom: Loss Of Power
When a camshaft wears, it will cause a knocking noise inside the engine. The camshaft is responsible for opening and closing the valves; when it wears, the valves will not close properly.
And so, there will be a loss of power inside the system, and the engine may not work.
Solution: Replace The Camshaft
- First, remove the old camshaft from the engine.
- Using a mechanic’s wire brush to clean the old camshaft sealant from the engine block and cylinder head.
- Once it is clean, use a wrench to remove the camshaft.
- Next, apply a light coating of petroleum jelly to the new camshaft. This will help it slide into place more easily.
- Carefully insert the new camshaft into the engine block and cylinder head. You may need to use a hammer to tap it into place gently. Make sure that it is fully seated before proceeding.
- Now, reinstall the valve cover and apply a new sealant around the edge. This shall do it!
2000 Polaris Sportsman 500 Problems
You can experience various problems with your 2000 Polaris Sportsman 500. This guide is designed to help you troubleshoot and repair some of the most common issues that can occur.

To unwind and clean the stator core, here are the steps you should follow:
- To do the job, you will need some essential tools such as a screwdriver, a pair of pliers, a hammer, a socket set, and a wrench.
- First, you have to remove the end cap. This can be done by unscrewing it.
- Once the end cap is removed, the windings can be unwound by gently pulling on them until they come loose.
- The windings can be cleaned after completely loosening them. This can be done by spraying them with a degreaser and wiping them clean with a cloth.
The other option is to replace the spark plug alongside the wires and coils. We have explained the process before.
Problem 2: Touchy Throttle
If a vehicle’s throttle is touchy, it is sensitive to the slightest touch. This means that the slightest movement of the accelerator will cause the vehicle to accelerate or decelerate.
This can be a big problem because it can make it difficult to control the vehicle’s speed while riding.
Symptom: Inconsistent Engine Respond
With a touchy throttle, the engine’s response to throttle input is unpredictable or varies from moment to moment. This can manifest as a jerky acceleration, sudden power loss, or a throttle that seems to jump from one setting to another.
Solution: Adjust And Clean The Throttle
The simple solution requires some attention and time, and here are the things to do:
- To adjust the throttle, locate the throttle linkage and use a screwdriver to adjust the screw-on end.
- Be careful to avoid overtightening it – just a few turns should do the trick.
- To clean the throttle, use a brush or a can of compressed air to remove any built-up dirt or debris.
If the problem doesn’t solve, take assistance from a good mechanic.
2006 Polaris Sportsman 500 Problems
Polaris has had its share of issues with the 2006 Sportsman 500. The ATV has been known to lose power randomly, leaving riders stranded in the middle of nowhere.
Problem 1: Bad Battery
Many Polaris Sportsman 500 owners have raised concerns about battery warning lights that keep flashing while driving. Bad battery issues are there in all of the models of the ATV but are more concentrated in the 2006 version.

Problem 2: Sensors Issues
There are various reasons why sensors malfunction inside a vehicle. One common reason is exposure to extreme temperatures. If a sensor is located in an area that is too hot or cold, it may malfunction and provide improper performance.
Sensor accuracy is key to fuel efficiency in any vehicle. If the sensors are not calibrated correctly or are dirty, the rider will not run as efficiently as it could. Also, any vibration or impact can damage sensors, which may stop working correctly.
Symptom: Loss Of Fuel Efficiency
The sensor is responsible for providing essential data to the engine management system, such as air-fuel ratio, engine temperature, and other information. If the data is incorrect or unavailable, the engine management system may use more fuel than necessary to operate.
This results in an inefficient burn and increased fuel consumption; thus, fuel efficiency depletes.
Solution: Replace Sensors
To remove an old sensor and install a new one inside a vehicle, the following tools may be required:
- Ratchet and socket set
- Wrench set
- Pliers
- Screwdrivers
And so, the process goes like this:
- Remove the old sensor from the vehicle. You just have to unscrew them, and they will come out.
- Next, install the new sensors by screwing them into the placement.
- Once placed, test the new installment for proper function.

Problem 1: Stiff Front Suspension
Riders often experience a stiff front suspension when they hit a bump or dip in the terrain. The improper inflation of the shocks can cause this, and the rider’s body weight is shifted too far forward.
When this happens, the bike’s weight is thrown forward, and the suspension cannot absorb the impact, which can cause the rider to be thrown from the bike.
Symptom: Vehicle Vibrating While Riding
When the front suspension is stiff, it does not move as much as when it is floppy. This means the ATV will vibrate more when ridden because the wheels cannot move as much.
Solution: Soften With Shock Absorber Oil Additive
The process involves a few steps:
- Add a small amount of special oil to your vehicle’s shock absorbers to help them absorb more impact and soften the ride.
- To do this, you’ll need to locate the shock absorbers on the rider. They’re usually located near the wheels, and you should be able to see the top of them sticking out from behind the wheel well.
- Once you’ve found them, remove the cap on the top and pour in the shock absorber oil additive.
- Make sure to read the instructions on the bottle to find out how much you need to add.
Replace the cap on the shock absorber and give it a few good shakes to mix in the additive. Then, take your ATV for a test drive. You should notice that the suspension feels softer and much smoother than before.
Problem 2: Clutch Problems
Over time, the clutch can become worn and start to slip, resulting in recurring clutch problems. In addition, the environment in which the ATV is being used can also cause problems, causing it to become worn and start to slip.
Symptom: Squeaking Noise On The Pedal
If the clutch is worn out or damaged, it won’t be able to provide the necessary friction to stop the ATV, leading to the squeaking sound. It would broadly impact the transmission system.
Solution: Replace The Clutch
Removing the old clutch to replace a new one can be done in a few simple steps.
The necessary tools are a lug wrench, a socket set, a clutch alignment tool, a clutch release tool, a torque wrench, and a flathead screwdriver.
With these, you can follow a few simple steps:
- Begin by draining the engine oil from the ATV and remove the clutch cover.
- Loosen the pressure plate and remove the clutch plates and springs.
- After this, disconnect the clutch cable from the clutch lever and remove the clutch assembly from the engine.

Polaris Sportsman 500 Problems With Other Models (2005, 2008, 2009, 2011, 2012, And 2013)
The Polaris Sportsman 500 ATV is known to have some common problems with different models. There are two real problems all these model owners have faced over the years.
Problem 1: Misaligned Wheels
Misaligned wheels can happen when the rider goes over bumps or turns too sharply. Polaris wheels can also lose alignment when the front or rear tires are not perpendicular to the ground.
When the wheels are not aligned properly, it can make it difficult to control the ATV and lead to accidents. Riding on an uneven surface can be tough due to incorrect tire pressure.
Symptom: Difficulty In Balance
When the wheels are misaligned, the machine pulls to the side or vibrates due to the wheels not being evenly matched. And so it will be difficult to balance while riding. There can be too little or too much tire pressure with a shaking and wobbling feeling in the handlebars. This indicates the time to seek good repairs.
Solution: Realign Wheels
To apply the proper fix, you have to check the wheel is misaligned. You can see whether the steering wheel is in the center position. If not, get ready for the solution.
Realigning the wheels on an ATV can be done by following these simple steps:
- Park the ATV on a level surface and remove the key from the ignition.
- Place a jack stand under the frame of the ATV and raise it until the wheels are off the ground.
- Use a wrench to loosen the lug nuts on the wheels.
- Carefully remove the wheels and re-align them using a straight edge. Once aligned, tighten the lug nuts back up and lower the ATV off the jack stand.
Do take professional help when you can’t do the job yourself.
Problem 2: Uncomfortable Seat
Several factors can make an ATV seat uncomfortable. One is the height of the seat about the handlebars. If the seat is too high, it can be difficult to reach the ground, making it hard to control the ATV.
Another problem is that the seat may not be wide enough, which can cause discomfort for some riders.
Symptom: Rider Fatiguing Quickly
The rider’s muscles are constantly working to keep them in balance and hold them upright, so when the seat is uncomfortable, it puts more strain on these muscles. This can cause the rider to fatigue quickly from using more energy than necessary.
Solution: Set The Saddle At Right Height
To set the saddle at the right height, the first step is to find the seat’s height. This can be done by measuring the distance from the ground to the center of the seat.
The second step is to set the saddle at this height. This can be done by adjusting the height of the forks on the ATV. This will solve the problem.
