Problem 1: Engine Gets Overheated

If you are a user of the Polaris Hawkeye 300, the first issue you can go through is the engine overheating problem. Overheating occurs when the engine temperature rises to a level that is higher than 200°F (93°C), which can cause damage to the engine and other components of the vehicle. 

The engine can get overheated due to several reasons. Let’s get to know the reasons and solutions respectively one by one. 

Reason 1: Restricted Fuel Lines

The fuel lines or jets of the engine can be restricted, resulting in an overheating issue. And it is the first possible reason why your Polaris Hawkeye 300 gets overheated. In the Polaris Hawkeye 300, the fuel lines are responsible for carrying fuel from the gas tank to the engine. 

The fuel is used to power the engine, but it also has a secondary function of cooling certain components in the engine. If the fuel lines become restricted or clogged, the flow of fuel can be impeded, which can lead to inadequate cooling of the engine components.  


You must check the fuel lines to find out if it’s restricted or not. If you find out your fuel line is full of debris and can’t provide enough fuel through the line, you have to clean the fuel lines. Also, regular maintenance and inspections can help identify and address any fuel line problems.

Reason 2: Float Level Is too Low 

If the engine is not getting enough oil to run the engine, it can be overheated. In fact, it’s the second most common reason for the engine getting too heated. The float level helps to regulate the temperature of the engine and prevents it from overheating. 

So if the float level is low, the engine may not be cool which leads to overheating the engine. 


You need to adjust the float height level. But the process is a bit tacky. You can take help from this video or visit a professional.

It’s also important to have any coolant leaks identified and repaired as soon as possible to prevent additional damage to the engine. 

Problem 2: Engine Backfires 

Polaris Hawkeye 300 engines backfire frequently, which is another major problem. Normally, backfiring occurs when fuel ignites outside of the combustion chamber, typically in the exhaust system or intake manifold. 

However, if the ignition timing or fuel-air mixture is incorrect, or if the exhaust system is malfunctioning, fuel can ignite in the intake manifold or exhaust system instead. 

So, when fuel ignites in the intake manifold or exhaust system, it produces a loud popping or banging sound, which is called engine backfiring.

Reason 1: Wrong Fuel Mixture

The most obvious reason is having the wrong fuel mixture. The correct fuel mixture is necessary for the engine to operate efficiently and smoothly. The engine may not be able to burn all of the fuel during combustion if the fuel mixture is too rich. It can cause engine misfires by allowing unburn fuel to enter the exhaust system.

On the other hand,  if the fuel mixture is too lean, there is not enough fuel in the air-fuel mixture, and the engine may not be able to ignite the mixture properly. So, the engine can backfire.


To get over damage and engine backfire, you need to maintain the correct fuel-gas (32:1) mixture for your Polaris Hawkeye 300. The octane must meet the number 87. 

So, do not ever use a fuel mixture that is too rich or too thin. In this case, you should follow the owner’s manual to find out the perfect fuel mixture ratio and fuel type. Remember to keep things in balance as they should be.

Reason 2: Clogged Air Filter & Carburetor

When the fuel mixture is perfectly fine, the problem could be with the air filter or carburetor. If the air filter and carburetor are clogged, fuel delivery gets interrupted and causes the engine to backfire.

You need to clean the air filter and the carburetor of all debris and contamination to make sure the smooth flow of the fuel. You can easily clean the air filter by following the guidelines. 

Required tools: Specialized cleaning kit

  • First, remove the air filter carefully. It can be found underneath your seat. Ensure no dust or particles fall into the intake or airbox when removing the air filter.
  • Now, spray the cleaner properly onto the filter. Then, pour the cleaning solution over the filter and allow it to soak for a few minutes.
  • Then, rinse the filter with water and dry it accurately before reinstalling it. 

You can clean the carburetor by following the same procedures as cleaning the air filter. However, before reinstalling it make sure you dry them completely with a can of compressed air.

Problem 3: The Engine Doesn’t Start 

If you’re a user of Polaris Hawkeye 300, this is another common problem you’ll face. While running the car you’ll experience that it drags or doesn’t start. If you experience such a situation, you need to determine what might be causing it.  

Reason 1: No Fuel 

The first probable reason is not having enough fuel in the tank. For the smooth operation and starting of the engine, an engine needs to have enough fuel.  


You should inspect the fuel tank and find out if there is fuel or not. The fuel level needs to be adjusted if the tank is running out of fuel.

Reason 2: Faulty Battery 

The second potential reason is having a faulty battery. If the battery is faulty, it will not be able to provide the necessary electrical energy to start the engine. The unit may be old, which is one of the reasons why your ATV battery keeps dying

It also may have lost its ability to hold much charge, or it may have been drained completely due to leaving the lights on or other electrical accessories. Also, damaged or corroded battery terminals can prevent the starter motor from receiving an electrical current.


To avoid a faulty battery, it’s necessary to inspect the battery at least once in 30 days. Also, recharge the battery if it’s drained. Then if the battery terminals are corroded, you should clean them to avoid any fault in the battery. 

You can use NOCO E404 as a battery corrosion cleaner. But If you’re a DIY person you can use coca-cola to remove the corrosion from the terminals. Replace the battery if it’s no longer functional. 

Reason 3: Clogged Fuel Valves

By delivering the right amount of fuel at the right time, the fuel system supports combustion. But if the fuel valves become clogged, the engine may not receive enough fuel to start or run properly. It can happen if the fuel valves become clogged due to debris and other contamination. 


You can observe any blockage with your naked eye by inspecting the valves properly. If you find any you should clean the valves properly. 

Required tools: Specialized cleaning solvent, and a soft-bristled brush 

Procedures:  You can follow the step below to clean the fuel valves.

  • First, disconnect the fuel supply and remove the fuel valves from the fuel rail or injector assembly. 
  • Then apply solvent in the valves. Now, gently scrub the fuel valves with the bristle brush and remove any remaining debris. 
  • At this point you must inspect the valves carefully, if you find any damage, you should replace them without ado. 
  • If it’s not damaged, reattach the fuel valves onto the fuel rail or injector assembly.  

Problem 4: Engine Losses Power

Polaris Hawkeye 300 also has a problem with its engine losing power sometimes. Going upwards or exposing it to rough terrain can cause this problem. If you don’t address the issue as soon as possible, it may cause serious harm.  

Reason: Worn-out Clutch 

The reason is quite obvious for this issue. In most cases, this can be attributed to a worn-out clutch.


The solution is very simple and that is to replace the worn-out clutch. Clutch components need to be replaced, and it isn’t a repair you can do alone. It is a complex and laborious process. You can check this video and try it all by yourself.

However, the job of replacing a clutch is best left to an automotive repair professional unless you have the necessary equipment and knowledge.

Problem 5: Engine Stalls And Bogs Down

The next issue that Polaris Hawkeye 300 faces are a stalling engine and bogging down. The engine stumbles several times when you’re running down a trail at a quarter throttle or so. Also, it can stop doing this if you open the throttle about halfway.  

Reason 1: Gummed-up Carb

If your carburetor is gummed up, it restricts the flow of fuel to the engine which result in the engine stalling and poor engine running. It is also one of the most common problems with the Honda Shadow 750. Carburetors become clogged with varnish and other debris when they become gummed up, causing the small passages and jets to block fuel flow.

You have to clean the gummed-up carburetor if you don’t want to have a poor running engine.

Required tools: Cleaning solution & soft-bristled brush

Procedures:  Here are the general steps to clean a gummed-up carburetor. 

  • First, disassemble the carburetor according to the instructions provided by the manufacturer.
  • The carburetor should be soaked thoroughly in a carburetor-cleaning solution.
  • Then, use the soft-bristled brush to gently scrub away any remaining debris.
  • Rinse the carburetor thoroughly with clean water and blow it dry with compressed air.

Reason 2: Faulty Spark Plug

The next possible reason is having a faulty spark plug. In the event that the spark plug fails to perform properly, the engine may not receive the proper spark to ignite the fuel, leading to a loss of power and eventual stalling.

In order to overcome the stalling and bogging, you must replace the faulty spark plug. If you want to do it yourself follow the video.

Even though the video instruction is of sportsmen there are a lot of similarities between hawkeye and this.

Reason 3: Contaminated Fuel 

The next reason would be having contaminated fuel. When fuel is contaminated, it can clog the fuel system and prevent the engine from receiving the proper amount of fuel.


If you suspect that your engine is stalling due to contaminated fuel, it is important to address the issue as soon as possible. You can start by draining the fuel tank and replacing the fuel. Please check the following video and take help from it.

Reason 4: Clogged Air Filter

The clogged air filter can also make your engine stall. The air filter can become clogged with these contaminants, which can restrict the flow of air into the engine.


The solution is pretty much obvious. You have to clean the air filter properly. You can follow the aforementioned procedures in the engine backfires section.    

Problem 6: Smoking Issues

Smoking problems may develop in the Polaris Hawkeye 300. If you notice smoke coming from the exhaust that smells like burning oil, it may be an indication that your engine is burning oil.

Reason 1: Dirty Air Filter 

The first reason would be having a dirty air filter. If the air passes blocks out, it can cause smoke.  


You can’t do anything other than clean the air filter. But you also have to inspect for any damage. If you found any damage you have to replace it.  

Reason 2: Dirty Carburetor

If you notice black smoke coming from the exhaust, it may be an indication that the fuel mixture is too rich. This can be caused by a dirty carburetor or fuel injection system. 


Dirty carburetor needs to be cleaned properly to solve the issue. You can do it following the guidelines in the engine backfires section. 

Problem 7: Idle Problems

There are also idle problems with the Polaris Hawkeye 300. It is usually too high or too low when the idle is too high or too low. Let’s find out the reason along with the solution.

Reason: Misadjusted Idle

A loose throttle cable or an improperly adjusted idle usually causes this problem. A worn or worn-out jet needle may also cause this problem if the choke cable is not adjusted properly.


To troubleshoot this problem, the first step is to verify if the idle is adjusted properly. If you have the manual, it can provide guidance on this. If the issue persists, the next course of action is to inspect the throttle and choke cables.

Finally, it is recommended to replace any worn-out jet needles. 

Problem 8: Excessive Vibration And Strange Noises

Sometimes Polaris hawkeye 300 goes through strange noises, especially when used regularly.  

Reason: Worn-out Bearings 

A worn-out bearing can cause excessive vibration and strange noise because it is no longer able to properly support the rotating shaft or component to which it is attached to. As a result, the shaft or component may start to wobble or vibrate, which can cause the entire system to shake and produce unusual sounds.

Bearings can become worn or damaged due to factors such as high loads, lack of lubrication, or contamination. When this happens, the bearing may develop rough spots or looseness that can cause vibrations and strange noises to occur.


If the bearings are falling, you have to replace them. It’s important to address any signs of excessive vibration or strange noise as soon as possible.
