How to Make a Yamaha Raptor 90 Faster

The Yamaha Raptor 90 brings maximum joy to an age group from 10 to 18 years old. It’s a low-maintenance ATV equipped with a 90cc engine. Although it’s a spectacular off-road bike, its engine’s capacity allows you to only experience mid-range performance.

The performance of the Yamaha Raptor 90 is determined by its top speed. Other factors affect the performance of this off-road bike, which we’ll cover in this post.

How Fast Can a Yamaha Raptor Go?

A 90cc Yamaha Raptor will run at 15-18 mph in normal conditions. The normal condition refers to the default speed limiter set by the factory. Moreover, the weight of the rider also impacts the bike’s top speed.

In normal conditions, Yamaha Raptor will retain its top speed if the rider weighs 80lbs. Now don’t get confused that a rider lighter than 80lbs can increase the performance of the ATV. That’s not how things work in off-road bikes.

However, if the rider’s weight is more than 80lbs, then the ATV’s top speed will be reduced. If you are looking for a faster ATV, CFMOTO ATV is one of the common names on the list.

Now, 15-18 mph sounds boring for some ATV fans. Although the speed limit is a safety feature for young riders, there’s still some room to enhance the performance of the Yamaha Raptor 90.

How to Increase Top Speed of Yamaha Raptor?

Although the speed limiter is the only factor that can be adjusted manually, this ATV is a marvel for your kids. You can easily increase the top speed of your Yamaha Raptor 90cc ATV by following these methods.

Throttle Screw

The throttle screw is one factor that limits the performance when you accelerate the ATV. To increase the top speed and allow the throttle to reach its top performance quickly, you have to adjust the stop screw.

First, unscrew the cover of the ATV’s throttle. It’s located on the handlebars. After uncovering the throttle, look for the throttle stop screw.

Now, adjust that screw. Make sure you don’t leave the screw wide open. Slightly increase its opening, and then cover the throttle screw again. That will increase the Yamaha Raptor 90cc ATV top speed by 30-33 mph. Moreover, now you can reach that speed quicker as well.

Adjust/Remove Jumper

Since the newer models of Yamaha Raptor ATV are restricted to going as fast as 15mph, you can’t check out its top performance. Therefore, there’s another method you can increase the top speed of your ATV.

You can adjust or remove the jumper wire located under the ATV’s seat. A jumper wire works as a speed limiter. So when you adjust or totally remove that, the top speed of your ATV will reach 29 mph from 15 mph.

So, first of all, remove the cover of the jumper terminal. It’s located under the ATV’s seat. You will find two screws holding the jumping wire in the terminal. Open the screws using a screwdriver.

After that, remove the jumper wire and then put back the screws. Finally, cover the jumper terminal. Now you can go faster on a Yamaha Raptor 90cc ATV.

Besides, you have to follow the same procedure to install the jumper wire back in the terminal.

Is Yamaha Raptor ATV Engine Powerful?

The Yamaha Raptor 90 uses a 90cc SOHC engine. This engine gives a varying performance, depending on the rider’s requirement. Since it uses an air-cooled system, you don’t have to worry about the heating up of the engine.

No doubt, the ATV running on off-roads gives load on a 90cc engine. But the engine works perfectly fine because of the default speed limiter. Plus, you won’t need a high-power engine like Toyota Tacoma pick-up trucks for off-roading.

Moreover, you can electrically start your Yamaha Raptor 90 using the PUSH-START button. Also, you will find an option to kickstart your ATV using the kick starter under the seat.

This ATV is made for newbies as it’s fully automatic. The young riders can easily learn how to ride an ATV with all the safety features activated.

In addition to that, Yamaha Raptor provides a reverse gear that increases the maneuverability of the ATV.

Besides, you can adjust the shocks of the Yamaha Raptor 90, which gives a unique sporty vibe.

Final Thoughts

The Yamaha Raptor 90 is a low-profile, comfortable ATV for kids. While your kid is in the learning phase, keeping the speed limiter at its default settings is recommended to mitigate the risk of getting injured. Once they cross the beginner’s level, you can increase the top speed of Yamaha Raptor 90 without any worry.
