What Exactly Is the Can-Am DS 90 Speed Limiter?
Before you start turning screws, it’s crucial to understand what you’re working with. The speed limiter on the Can-Am DS 90 isn’t a complex electronic nanny or a mysterious black box. It’s a brilliantly simple and effective mechanical device.
Think of it as a physical “stop.” The device is essentially a long screw located in the throttle lever housing on the right handlebar. This screw’s job is to physically block the thumb throttle lever from being pushed all the way.
When you turn the screw in, it protrudes further into the housing, reducing the distance the throttle lever can travel. Less throttle travel means less fuel and air go to the engine, which directly limits the ATV’s maximum speed. When you turn the screw out, the throttle has more room to move, allowing for higher speeds. It’s a direct, mechanical connection that gives you precise control over the machine’s power output.
This simple mechanism is the heart of this youth ATV’s safety system, making this can am ds 90 speed limiter guide your first stop before your kid’s first ride.
The Real Benefits of Using the Can-Am DS 90 Speed Limiter Correctly
Some folks might be tempted to back the limiter all the way out from day one, but that’s a huge mistake. Properly managing the speed limiter offers massive advantages for both the rider and your own peace of mind. The true benefits of can am ds 90 speed limiter usage go far beyond just slowing the machine down.
Building Rider Confidence, Not Fear
An overpowered machine is intimidating for a new rider. When a simple twitch of the thumb sends them rocketing forward unexpectedly, it creates fear and hesitation. By setting the limiter to a walking pace initially, you allow them to master steering, braking, and body position without the added stress of high speed.
This builds a strong, confident foundation. They learn the machine’s dynamics in a controlled environment, which is far more effective than learning through a series of scary close calls.
A Progressive Learning Tool
The DS 90 speed limiter isn’t a “set it and forget it” feature. It’s a dynamic training tool. As your child demonstrates mastery of the basics, you can gradually give them a little more speed. This progression is key.
Each small increase feels like a reward for their improving skills. It keeps them engaged and allows them to adapt to new speeds incrementally, ensuring they are always in control and never overwhelmed.
Enhancing Safety and Peace of Mind
This is the big one for parents and guardians. Knowing you have set a safe top speed allows you to relax and focus on coaching. You can be confident that your rider won’t accidentally whiskey-throttle into a dangerous situation they aren’t equipped to handle.
This feature transforms riding sessions from stressful supervision into enjoyable, shared experiences. It’s the most critical safety tool you have for preventing accidents before they happen.
How to Adjust the Can-Am DS 90 Speed Limiter: A Step-by-Step Guide
Alright, let’s get to the nuts and bolts. Adjusting the limiter is a simple process that takes less than five minutes. Here’s how to can am ds 90 speed limiter adjustment is done correctly and safely.
Tools You’ll Need
You don’t need a full toolbox for this job. In most cases, all you’ll require is:
- A 10mm wrench (or a small adjustable wrench)
- A flathead screwdriver
That’s it. Make sure your tools are in good condition to avoid stripping the hardware.
Locating the Throttle Limiter Screw
Have your rider sit on the ATV. On the right handlebar, you’ll see the thumb throttle assembly—the black housing where the throttle lever pivots. On the front side of this housing, facing forward, you will see a screw with a 10mm lock nut around its base. This is your target.
The Adjustment Process
Follow these steps carefully. Always perform adjustments with the engine turned off.
- Ensure the ATV is Off: Make sure the key is out and the engine is cool. Park it on a level surface.
- Loosen the Lock Nut: Use your 10mm wrench to turn the lock nut counter-clockwise just enough to loosen it. You don’t need to remove it completely, just break it free so the screw can turn.
-
Adjust the Screw: Now, use your flathead screwdriver to turn the center screw.
- To decrease speed, turn the screw clockwise (in). This will restrict the throttle lever’s movement. For a brand-new rider, you may want to turn it almost all the way in.
- To increase speed, turn the screw counter-clockwise (out). This will allow the throttle lever to be pushed further.
- Test the Feel: Before tightening anything, have the rider press the thumb throttle. They should immediately feel the difference in how far it can travel. Adjust until you have a very short, limited throw for the first ride.
- Tighten the Lock Nut: Once you’re happy with the position, hold the screw steady with the screwdriver and use the 10mm wrench to snug the lock nut back down by turning it clockwise. This is a critical step to prevent the screw from vibrating loose.
- Perform a Safety Test: Start the ATV in a wide-open, safe area. Have the rider test the speed. If it’s still too fast, shut it off and turn the screw in a bit more. Only make small adjustments at a time.
One of our most important can am ds 90 speed limiter tips is to always re-tighten that lock nut. A loose limiter screw can back out on its own during a ride, unexpectedly giving your new rider a sudden burst of speed they aren’t ready for.
Common Problems with the Can-Am DS 90 Speed Limiter and How to Fix Them
While the system is simple, you can occasionally run into a snag. Here are a few common problems with can am ds 90 speed limiter mechanisms and what to do about them.
Limiter Screw is Stuck or Stripped
If the screw or lock nut won’t budge, it’s likely corroded. Spray a small amount of penetrating oil (like PB B’laster or WD-40) on it and let it sit for a few minutes. Make sure you are using the correct size wrench (10mm) to avoid rounding off the nut. If the screwdriver slot is stripped, you may need to use a pair of locking pliers to carefully grip the screw head to turn it.
ATV Still Seems Too Fast or Boggy
If you’ve turned the screw way in and the quad still feels too fast, double-check the engine’s idle speed. If the idle is set too high, the ATV will want to creep forward on its own. Conversely, if the machine feels boggy or unresponsive even with the limiter backed out, the issue may lie with the carburetor or air filter, not the limiter itself.
Inconsistent Throttle Response
If the throttle feels sticky or doesn’t return smoothly, the problem is likely the throttle cable, not the limiter screw. Inspect the cable for any frays, kinks, or dirt. A frayed cable is a major safety hazard and should be replaced immediately. You can try lubricating a sticky cable, but replacement is often the best long-term solution.
Best Practices for a Sustainable and Safe Riding Experience
Your job doesn’t end after the initial adjustment. Adopting a few best practices ensures a safe and positive experience for years to come. This is about creating a mindset, not just setting a screw.
Matching Speed to Terrain and Skill
A speed that’s safe on flat grass can be dangerously fast on a rocky trail or a steep hill. Teach your rider that the limiter sets the maximum potential speed, but it’s their job to use judgment and ride even slower when conditions demand it. This is one of the most vital can am ds 90 speed limiter best practices.
The Eco-Friendly Approach: Teaching Throttle Control
A truly sustainable can am ds 90 speed limiter philosophy extends to riding habits. Teach your rider to be smooth with the throttle. Jerky, on-off throttle application is hard on the machine’s drivetrain, burns more fuel, and tears up the trails. Smooth control is the mark of a good rider and is a more eco-friendly can am ds 90 speed limiter practice that protects both the machine and the environment.
Regular Checks: Your Pre-Ride Care Guide
Incorporate a check of the speed limiter into your pre-ride inspection. As part of your can am ds 90 speed limiter care guide, simply press the throttle with the engine off to confirm it has the limited range of motion you expect. Vibrations can sometimes loosen things, and a 10-second check can prevent a surprise.
Frequently Asked Questions About the Can-Am DS 90 Speed Limiter
What is the top speed of a Can-Am DS 90 with the limiter disabled?
A stock Can-Am DS 90, with the limiter screw backed all the way out, can typically reach speeds of around 15 mph, depending on rider weight and terrain. This is plenty fast for a young, inexperienced rider, which is why using the limiter is so important.
Can I completely remove the speed limiter screw?
You can, but you shouldn’t. Removing it offers no performance benefit over simply backing it all the way out. You risk losing the screw and lock nut, and you lose the ability to quickly and easily restrict the speed when a younger or less experienced friend wants to take a turn.
How often should I adjust the speed limiter?
Adjust it based on your rider’s demonstrated skill and comfort level. After they’ve mastered the current speed setting—showing good control over braking, turning, and throttle modulation—you can give them a small increase. This could be every few weeks or every few months; let their ability, not their requests, be your guide.
Properly managing the speed limiter on your Can-Am DS 90 is one of the most responsible things you can do as a parent or guardian. It’s a simple tool that pays huge dividends in safety, confidence, and fun.
By following this guide, you can make informed adjustments, troubleshoot any issues, and help foster a lifelong love for off-roading in your young rider. Now get out there, adjust with confidence, and make some incredible memories on the trails. Ride safe!
