Now let’s get to the explanation.
Problem 1: Engine Not Turning On
This is probably one of the most common problems for any type of vehicle. However, the Polaris hawkeye 300 4×4, 2007 model has come with a 4-stroke, air-cooled, single-cylinder SOHC engine.
This type of engine won’t start for certain reasons.
Reason 1: Clogged Carburetor
The clogging in the carburetor can cause the engine not to turn on. When the carburetor gets clogged, fuel can’t flow into the engine operating parts.
Let’s look at the Polaris hawkeye 300 carburetor diagram to understand better how clogging stops the engine from working.

In the diagram, marks 41 to 38 indicate the carburetor from where fuel runs into the engine. Clogging in this region can prevent the engine from getting started.
Solution 1: Clean and Unclog Carburetor
It is important to follow proper guidelines when removing and unclogging debris from the carburetor. Here are the steps you need to follow.
Step 1: A carburetor must first be removed from the main engine in order to be unclogged. Make sure the air filter is properly closed before removing it. Don’t leave the fuel tank running, or you’ll waste fuel.
Step 2: In this part, you need to remove the carburetor hose completely. And then the best solution is to use a high-pressure air pumper to pump through the hose. High-pressure air can remove normal blockage and debris.
Step 3: After giving air pressure into the carburetor hose, next you need to wash it with engine washing thinner. And then set the carburetor as it was.
Reason 2: Loose Connection in Ignition
When a voltage is delivered down, the HT leads a spark that jumps between the spark plug’s center electrode and its ground electrode. The piston moves down the cylinder when the spark ignites the air/fuel mixture. And that’s how the engine gets started.
It is impossible to perform this entire procedure when the ignition connection is loose. The engine won’t start because of this.
Solution 2: Connect the Ignition Wire Properly
Changing the ignitor is the best solution for this issue. However, there is a DIY solution for repairing the loose connection on the ignitor as well.
Here are the step-by-step guides.
Step 1: Unscrew the ignition panel located below the steering. Can you see if the ignition tip wire is properly connected or not?
Step 2: After that, you connect the wire with the ignition properly. Be careful about the negative and positive wires.
Problem 2: Engine Backfire
Another common problem of Polaris Hawkeye 300 is engine backfire. It is best to avoid backfires since they can damage engines, reduce power, and reduce fuel economy.
And gradually, backfires can destroy the whole engine.
Reason 1: Air Leak In The Oxygen Sensor
One of the main reasons behind engine backfire is oxygen sensor leakage. Fuel that has been partially burned or unburned enters the system and ignites when the oxygen concentration rises.
If the exhaust manifold gasket leaks or the exhaust pipe sealing ring breaks, extra oxygen might enter the engine. And for this reason, engine backfires happen.
Solution 1: Replace Oxygen Sensor or Fix the Leak with Insulin Tape
The best solution for a leaking oxygen sensor is the replacement. Because fixing the oxygen sensor is not a permanent solution.
However, we have one for you if you want a temporary DIY solution. Let’s see what the solution is for a leaking oxygen sensor.
Step 1: You just need waterproof insulin tape to fix the oxygen sensor leakage. Make sure the tape is thick enough for air resistance. In this step, first, you need to find the spot of leakage.
And to do this, you just need to ignite the engine. And at the same time, rub your fingertip all over the sensor and find out the leakage.
Step 2: Cover the leaking spot with insulin tape after finding out the leakage. Cover 2/3 inches extra. Use at least 3 or 4 rounds of insulin tape to cover it.
Reason 2: Faulty Ignition
A faulty ignition system is another cause of engine backfiring. As we mentioned earlier in this article, ignorance is a key factor in starting an engine.
An igniter creates a spark in the engine, which drives the motor. The engine starts as a result of this motion. The whole process is hampered by a defective ignition.
Solution 2: Spray WD40 in the Igniter and Arrange a New Key
Faulty ignition results from a broken or shape-changed key. So, you need to make a new key from a locksmith. After that, there are some simple steps to get rid of the faulty ignition. Let’s jump into the steps directly.
Step 1: First, you need to spray some WD40 cleaner into the ignitor. And after that, wait for at least 5 minutes.
Step 2: After 5 minutes of waiting, clean the ignitor with cotton buds. And jiggle the ignitor with the newly made ignition key.
Problem 3: Engine Overheat
Engine overheating is a common problem for almost all types of vehicles. Polaris hawkeye 300 engines also can overheat. And overheating can cause the engine to stop suddenly. At the same time, the engine can lose its power.
There can be certain reasons behind this issue. Here we’ll discuss the possible reason.
Reason: Contaminated Fuel
Contaminated fuel can cause the engine to overheat most of the time. In terms of contaminated fuel, there are different types. Unused fuel, fuel that has been stored for a long time, is also considered contaminated fuel. All of these types of fuel can cause an engine to overheat.
A blockage in the fuel filter is caused by contaminated fuel. As a result, the cooling system cannot function properly. Engine Mobil cannot control overheating because it cannot reach the engine. This is a major cause of engine overheating.
Solution: Clean Fuel Filter and Refuel
The only solution for this problem is removing the bad fuel and refueling with the refined fuel. And to do this, you need to follow some simple instructions.
Step 1: First, you need to remove all the contaminated fuel. And after that, you need to clean the fuel filter very carefully.
Step 2: After cleaning the fuel filter, you need to refuel your Polaris Hawkeye 300 with refined fuel. To avoid contaminated fuel, you can use an external filter whenever you fuel your Polaris.
Problem 4: Low Fuel Efficiency
Low fuel efficiency is a common problem in the Polaris Hawkeye. And for this problem, expense increases. And gradually, the capacity of the engine can decrease. Let’s see what the reason behind this problem is.
Reason: Bad Fuel Injector
There are some specific reasons behind low fuel efficiency. But the most common reason is the faulty fuel injector. A bad fuel injector causes fuel blockage. And for the improper transformation of fuel, the efficiency decreases.
Solution: Change the Fuel Injector
The only solution for the bad fuel injector is to replace the injector. But the replacement of the fuel injector isn’t an easy task. So it’s better to call an expert for the service. If you don’t have enough ideas about the diagram, there is a high chance of disassembling it.
How Fast Does A Polaris Hawkeye 300 Go?
A Polaris hawkeye normally has a peak speed of 65 kilometers per hour. It is possible to have a different speed limit depending on the quality of the road. Polaris can’t go too fast because it’s made for offroad riding and climbing hills, so it’s not as fast as regular vehicles.
How Do You Tell What Year My Polaris Hawkeye Is?
You can tell the year of your vehicle by using the VIN. You can easily determine the year of your Polaris Hawkeye by entering the VIN number into the VIN tool. In the user manual of your Polaris hawkeye, you can find the VIN number.
How Much Oil Does Polaris Hawkeye Hold?
Fuel capacity for the Polaris Hawkeye ranges from 7.5 to 12.5 gallons. In liters, the Polaris Hawkeye can hold 28 liters to 47 liters of oil, depending on the model. More than 250 to 50 kilometers can be covered with this amount. With such a large fuel capacity, you won’t have to worry about running out of gas during long journeys.
Well, this was all about the Polaris Hawkeye 300 problems. There are a few common problems we’ve discussed here. By now, you should be aware of the types of problems that the Polaris Hawkeye 300 is capable of experiencing.
Consult an expert if problems seem severe. However, there are many DIY solutions available for a variety of issues. It’s only permissible if you have little understanding.
