Ways to Increase the Speed of your ATV
The good thing about investing in a quality ATV is that simple adjustments can quickly increase its speed. Here are some minor adjustments you can make to your ATV to boost its speed.
Clean The Air Filter
A simple task such as ensuring that your air filter is clean before going for a race can tremendously increase the speed of your ATV. Clogged air filters interfere with the airflow to the combustion chamber, thus preventing the complete combustion of fuel for energy production. In addition, you should ensure that you use better fuel.
Another recommendation to increase your ATV speed is to ensure the tires have enough pressure. Always ensure that you have quality tires that are easy to inflate. Additionally, before going out for a race, you should ensure that the tires are in perfect condition.
Besides the air pressure, it is crucial to understand that tire size can also influence the speed of your ATV. Small tires are the best when you are after an acceleration on a flat surface. On the other hand, big tires will be the most appropriate when riding on rough terrain.
Upgrade The Exhaust
Upgrading your ATV's exhaust can also play a significant role in increasing the speed of your ATV. When waste products of the combustion can leave through the exhaust quickly, the engine can pull more air for efficient combustion. In most cases, excellent exhaust systems usually are big.
Change The Gear Ratio
Lastly, changing the gear ratio can play an essential role in enhancing its speed. Gear-up increases can increase the speed of your ATV instead of gear-down, which reduces the top speed while increasing the acceleration.
The Honda 400ex top speed is about 75 MPH. While that is a pretty fast speed, you can always carry out some modifications to increase the speed of your Honda 400EX even further. Some minor modifications that can help increase the speed of your ATV include, installing a big bore kit, changing the gear ratio, upgrading the exhaust, adjusting the throttle limiter, and many others.
