What is the Polaris Outlaw 50 Throttle Screw and Why Does It Matter?

Before we start turning wrenches, it’s essential to understand what this part does. Think of it less as a performance part and more as a built-in safety instructor for your ATV.

The throttle screw on a Polaris Outlaw 50 isn’t for adjusting idle speed; it’s a throttle limiter. Its sole job is to physically stop the thumb throttle lever from being pushed all the way. This directly controls the maximum speed the ATV can reach.

The Core Benefits of Using the Throttle Limiter

Properly managing this screw offers huge advantages, especially for parents and new riders. The primary benefits of polaris outlaw 50 throttle screw size adjustment are all about control and safety.

Gradual Skill Building: You can set the top speed to match your child’s current skill and comfort level. As they become a more competent rider, you can gradually allow more power.
Enhanced Safety: For first-timers, limiting the speed prevents the ATV from getting away from them, reducing the risk of accidents caused by whiskey throttle or panic.
Parental Peace of Mind: Knowing you have set a safe maximum speed allows you to supervise with less anxiety, making the experience more enjoyable for everyone.
Controlled Learning Environment: It allows a young rider to master steering, braking, and body positioning without also having to manage excessive speed.

The Exact Polaris Outlaw 50 Throttle Screw Size and Tools You’ll Need

Alright, let’s get down to the nuts and bolts—literally. The “size” question can be a bit tricky. You’re not looking for the thread pitch of the screw itself, but rather the tools required to adjust it. The setup is designed for easy access and adjustment.

The throttle limiter consists of a screw and a lock nut. The screw itself typically has a Phillips or flathead slot, but the critical part is the lock nut that holds it in place.

The lock nut on most Polaris Outlaw 50 models is a 10mm hex nut. This is the most important measurement you need.

Your Essential Toolkit for the Job

You don’t need a professional rollaway chest for this task. Gather these simple tools before you begin:

10mm Wrench: A small combination wrench or a socket will work perfectly to loosen and tighten the lock nut.
Phillips or Flathead Screwdriver: To turn the actual limiter screw once the lock nut is loose. A multi-bit screwdriver is a great tool to have on hand.
Safety Glasses: Always a good idea when working on any vehicle.
Mechanic’s Gloves: To keep your hands clean and improve your grip.

Step-by-Step Guide: How to Polaris Outlaw 50 Throttle Screw Size Adjustment

Now for the hands-on part. Follow these steps carefully for a safe and effective adjustment. This process is simple and should only take a few minutes.

Step 1: Safety First – Prepare the ATV
Before you touch any tools, ensure the ATV is in a safe state. Park it on a level surface, turn the engine completely off, and remove the key. Let the engine cool down if it has been running recently.
Step 2: Locate the Throttle Limiter Assembly
You’ll find the throttle limiter on the right-hand side of the handlebars, integrated into the thumb throttle housing. Look for a screw with a nut cinched up against the housing. This is your target.
Step 3: Loosen the Lock Nut
Take your 10mm wrench and place it on the lock nut. Turn it counter-clockwise just enough to break it loose. You don’t need to remove it completely—a half-turn is usually sufficient to allow the screw to move freely.
Step 4: Make the Adjustment
Now, use your screwdriver to turn the limiter screw. The logic is very simple:
- To Decrease Speed (More Restriction): Turn the screw IN (clockwise). This makes the screw protrude more on the inside, physically stopping the throttle lever sooner.
- To Increase Speed (Less Restriction): Turn the screw OUT (counter-clockwise). This retracts the screw, allowing the throttle lever to be pushed further.
Pro Tip: Make small adjustments at first, like a quarter or half-turn at a time. It’s easier to give a little more power later than to deal with an unexpected jump in speed.
Step 5: Tighten the Lock Nut
Once you’ve set the screw to your desired position, hold the screw steady with your screwdriver to prevent it from moving. Use your 10mm wrench to tighten the lock nut (clockwise) firmly against the housing. It should be snug, but don’t overtighten and risk stripping it.
Step 6: Test the Adjustment Safely
This is the most important step. First, with the engine still off, push the thumb throttle. You should feel it stop at the new position. Next, start the ATV in neutral on level ground. Gently apply the throttle to see how the engine revs. Finally, have the rider, wearing all their safety gear, test the ATV in an open, controlled area to confirm the new top speed is appropriate for their skill level.

Common Problems with Polaris Outlaw 50 Throttle Screw Size and Adjustments

Even a simple job can have its hiccups. Here are a few common issues you might encounter and how to solve them, turning potential frustration into a quick fix.

Problem 1: The Lock Nut or Screw is Seized

If the nut or screw won’t budge, don’t force it and risk stripping the head. Dirt, grime, or a little rust can cause it to seize. Apply a small amount of penetrating oil (like PB B’laster or WD-40) and let it sit for a few minutes before trying again. Ensure your wrench and screwdriver are seated properly for maximum grip.

Problem 2: ATV Bogs Down or Won’t Idle After Adjustment

The throttle limiter should not affect the idle. If the ATV starts acting strangely after an adjustment, you may have turned the screw in so far that it’s slightly engaging the throttle cable even at rest. Back the screw out a tiny bit. If the problem persists, the issue may lie with the separate idle adjustment screw or a dirty carburetor, not the limiter.

Problem 3: The Adjustment Keeps Loosening

Vibrations from riding can sometimes work the lock nut loose over time. If you find you’re constantly readjusting it, ensure you’re snugging it down properly. For extra security, you can apply a single drop of a non-permanent, medium-strength threadlocker (like Blue Loctite 242) to the screw’s threads before tightening the lock nut. This will hold it in place without making future adjustments impossible.

Polaris Outlaw 50 Throttle Screw Size Best Practices for Safety and Performance

Getting the technical adjustment right is only half the battle. Following these best practices will ensure long-term safety and make the entire experience better for your young off-roader.

Start Slow, Go Slow: When introducing more speed, always do it in very small, manageable increments. A quarter-turn of the screw can make a noticeable difference.
Adjust for the Terrain: A safe speed for an open, flat field might be too fast for tight, wooded trails. Consider the riding environment when setting the limit.
Communicate with Your Rider: Talk to your child about the change. Let them know you’ve allowed a little more speed and remind them to be cautious as they get used to it.
Perform Regular Checks: As part of your pre-ride inspection (checking tire pressure, fuel, etc.), give the throttle limiter a quick look to ensure the lock nut is still tight. This is a key part of any good polaris outlaw 50 throttle screw size care guide.

Thinking Green: Sustainable Polaris Outlaw 50 Throttle Screw Size Management

At FatBoysOffroad, we believe enjoying the outdoors means preserving it. While a throttle screw might not seem related to being eco-friendly, a responsible mindset connects everything.

A properly adjusted throttle ensures the engine operates within its intended range for the rider’s skill, preventing inefficient, high-revving situations that waste fuel. This is a core principle of a sustainable polaris outlaw 50 throttle screw size approach.

Furthermore, teaching a young rider to manage their speed responsibly helps prevent them from tearing up trails, causing erosion, and disturbing wildlife. Responsible riding habits are the most eco-friendly polaris outlaw 50 throttle screw size practice there is. It all starts with that first, controlled ride.

Frequently Asked Questions About the Polaris Outlaw 50 Throttle Screw Size

What tools do I need to adjust the Polaris Outlaw 50 throttle screw?

You primarily need a 10mm wrench (or socket) to loosen the lock nut and a Phillips or flathead screwdriver to turn the adjustment screw itself. It’s a very simple toolkit.

How do I know when my child is ready for more speed?

Look for signs of confidence and control. Are they consistently using their brakes correctly? Can they navigate turns without difficulty? Do they handle small bumps with proper body positioning? If they have mastered the current speed setting and are asking for more, it’s likely a good time for a small, incremental increase.

Can I just remove the throttle limiter screw completely?

While you physically can, we strongly advise against it, especially for young or inexperienced riders. The Outlaw 50 is designed as a youth ATV, and this safety feature is a critical part of its design. Removing it gives the rider access to 100% of the power instantly, which can be overwhelming and dangerous.

Does adjusting the throttle limiter affect the ATV’s idle speed?

No, it should not. The throttle limiter screw is separate from the carburetor’s idle adjustment screw. The limiter only affects the maximum throttle input, not the engine’s speed at rest. If your idle changes, you should investigate the carburetor or idle screw.

You now have all the expert knowledge needed to manage your child’s ATV speed like a pro. Adjusting the throttle limiter is one of the most empowering and important bits of maintenance you can perform on a youth ATV. It puts control firmly in your hands, allowing you to create a safe, fun, and progressive learning curve for your young rider.

So grab your 10mm wrench, follow these steps with confidence, and get back to what matters most: making incredible memories on the trail. Stay safe and ride on!
