Reasons for throttle cutting out

Here are the reasons why the throttle cuts out and causes complications.

Malfunctioning ignition system

The ignition problem is one of the important causes behind the throttle cutting out. Weak ignition coil, faulty spark plug, and wiring issues are the root causes of the malfunctioned ignition system. 

How to fix it

First of all, check the spark plug or ignition coil to see signs of damage. A worn-out coil or spark plug harms the vehicle severely. Go for its repair if possible otherwise, replacement is the only solution to fix the problem.

Bad throttle

If the throttle sensor is faulty, clogged, or damaged or its motor is failed then it leads to cutting out. Regular inspection is necessary to extend the lifespan of the engine.

How to fix it

• Replace the damaged motor or sensor if they can’t be repaired easily but the best way to get rid of this problem is to install a new throttle instead of going for expensive repairs. 
• Remove the throttle body from the ATV and clean it.
• Properly adjust the throttle cable and make sure it is fully tightened.

Malfunctioning carburetor

Carburetor mixes air and fuel in the engine which ensures efficient combustion. Any issue with the carburetor may lead to throttle cutting out. So it is always advised to keep checking it for the smooth running of your vehicle.

How to fix it

Check the carburetor of your ATV, clean it properly, and if there are signs of damage repair it if it cannot be repaired then replace it as soon as possible to increase the life of your vehicle. A faulty carburetor damages the engine that causes further complications.

Clogged air filter

Since ATVs is an off-road vehicle, therefore, dirt and dust easily enters the system. A dirty or clogged air filter restricts the flow of air to the engine which leads to the cut-out or stalling of the throttle.

How to fix it

Make sure to clean air filters regularly to avoid damage to your vehicle. Blow out air filters to get rid of all dirt and dust.

If it is fully damaged then go for its replacement. Proper and regular service keeps the vehicle free from major damages and expensive repairs. 

Fuel delivery system issue

Another reason for ATV throttle cutting out is a faulty fuel delivery system. If there is a problem in the fuel system it obstructs the flow of fuel to the engine.

This faulty system is a sign that your vehicle needs proper care and repairs and if not sorted in time, they may vandalize your vehicle in the long run. 

How to fix it

Sometimes the fuel system gets clogged so it is mandatory to clean it regularly. Take a brush and clean all parts. You can use good quality cleaning solution for this purpose.

If cleaning doesn’t fix the problem then it needs replacement to make everything work properly.
