The Necessity of Upgrading to a Yz 85 Big Bore Kit

As an avid motocross rider, I have always been on the lookout for ways to improve the performance of my bike. After doing some research and talking to fellow riders, I decided to upgrade my Yz 85 with a big bore kit. And let me tell you, it was one of the best decisions I have ever made.

Firstly, a big bore kit increases the displacement of your engine, which means more power. The stock Yz 85 has a displacement of 84cc, but with a big bore kit, you can increase it up to 105cc. This translates to a significant boost in horsepower and torque, making your bike more powerful and responsive on the track.

Moreover, upgrading to a big bore kit also means upgrading other essential components such as the cylinder, piston, and gaskets. These components are designed to handle the increased power and provide better performance and durability. With a bigger engine, your bike will be able to handle tougher terrains and obstacles without breaking down.

Another reason why a big bore kit is necessary for your Yz 85 is that it allows you to keep up with higher cc bikes on the track

My Buying Guide on ‘Yz 85 Big Bore Kit’

As a proud owner of a Yz 85 dirt bike, I have always been looking for ways to enhance its performance. After doing some research, I came across the idea of installing a big bore kit to increase the engine’s displacement and horsepower. After some hesitation, I decided to take the plunge and invest in a Yz 85 big bore kit. In this buying guide, I will share my personal experience and provide you with all the necessary information to help you make an informed decision.

What is a Big Bore Kit?

A big bore kit is essentially an aftermarket upgrade that increases the size of your engine’s cylinder and piston. The larger displacement allows for more fuel and air mixture, resulting in increased power and torque. In the case of the Yz 85, it typically increases the bike’s displacement from 85cc to 105cc.

Why Upgrade to a Big Bore Kit?

The main reason for upgrading to a big bore kit is to improve your bike’s overall performance. With a larger displacement, you can expect increased power and torque, which translates into faster acceleration and higher top speed. It also provides you with more low-end torque, making it easier to climb steep hills or navigate through rough terrains.

Another benefit of installing a big bore kit is that it can prolong the lifespan of your engine. With more surface area on the cylinder walls, there is less stress on each stroke, resulting in less wear and tear on your engine.

What to Consider Before Buying

Before purchasing any big bore kit for your Yz 85, there are a few factors that you should consider:

  • Bike Compatibility: Not all big bore kits are compatible with every dirt bike model. Make sure to check if the kit you are interested in is suitable for your specific year and model of Yz 85.
  • Budget: Big bore kits can range from $200-$500 depending on the brand and quality. It’s important to set a budget beforehand and stick to it.
  • Brand Reputation: Do some research on different brands and read reviews from other customers before making your purchase. A well-known brand with positive customer reviews will give you peace of mind knowing that you are investing in a quality product.
  • Horsepower Increase: Depending on your riding style and preferences, consider how much horsepower increase you want from your bike after installing the big bore kit. Some kits may offer more significant gains than others.

The Installation Process

If you have mechanical experience or feel confident enough to install the big bore kit yourself, then go ahead! However, if you are not familiar with engine modifications or do not have access to proper tools, it is best to seek professional help. Improper installation can cause serious damage to your engine or even put yourself at risk while riding.

In Conclusion

I have been extremely satisfied with my decision to upgrade my Yz 85 with a big bore kit. The increase in power has made my rides much more enjoyable and has improved my overall riding experience. However, it’s essential to do thorough research before making any modifications to your dirt bike’s engine as it can be costly if not done correctly.

I hope this buying guide has provided valuable insights into what factors should be considered when purchasing a Yz 85 big bore kit. Happy riding!
