The Necessity of a Yz 85 Big Bore Kit: My Personal Experience

As a motocross enthusiast, I have always been on the lookout for ways to improve my bike’s performance. One upgrade that has made a significant difference in my riding experience is installing a Yz 85 big bore kit. This modification involves increasing the engine displacement by replacing the stock cylinder and piston with larger ones.

Firstly, a big bore kit increases the overall power and torque of the bike. The larger displacement allows for more fuel and air to be compressed, resulting in a stronger combustion and ultimately more power being generated. This is especially beneficial for riders who participate in races as it provides them with an edge over their competitors.

Another reason why a big bore kit is necessary is its impact on the bike’s top speed. With increased power comes increased speed. By upgrading to a bigger cylinder and piston, I have been able to achieve higher top speeds, making my rides more thrilling and exciting.

Furthermore, a big bore kit also improves the bike’s low-end torque. This means that there is more power available at lower RPMs, making it easier to navigate through tight corners or tricky terrains. This has greatly enhanced my riding experience as I no

My Buying Guide on ‘Yz 85 Big Bore Kit’

Hello fellow riders! As an experienced motocross rider, I know the importance of having a reliable and high-performing machine. That’s why I decided to upgrade my Yz 85 with a big bore kit. After thorough research and personal experience, I have put together this buying guide to help you make an informed decision when purchasing a Yz 85 big bore kit.

What is a Big Bore Kit?

A big bore kit is a performance upgrade for your motorcycle’s engine. It includes larger cylinder and piston sizes, increasing the engine’s displacement and ultimately improving its power and torque output. In simple terms, it makes your bike faster and more powerful.

Why Choose a Yz 85 Big Bore Kit?

The Yz 85 is already known for its impressive power and performance in the motocross world. However, with a big bore kit, you can take your bike to the next level. The Yz 85 big bore kit not only increases the displacement but also improves the engine’s overall durability and reliability, making it perfect for intense riding and racing.

Factors to Consider

  • Brand: When it comes to performance upgrades, choosing a reputable brand is crucial. Look for brands that have been in the market for a while and have positive reviews from other riders. For Yz 85 big bore kits, popular brands include Athena, Pro X, and Wiseco.
  • Compatibility: Not all big bore kits are compatible with every bike model. Make sure to check if the kit you’re interested in is suitable for your specific Yz 85 year and model.
  • Cylinder Material: The cylinder material plays a significant role in the durability of your big bore kit. Aluminum cylinders are lighter but less durable compared to steel or iron cylinders which are heavier but more robust.
  • Piston Material: Similar to cylinders, pistons can be made of different materials such as cast aluminum or forged aluminum. Forged pistons are stronger than cast pistons but also come at a higher price point.

Budget

The cost of a Yz 85 big bore kit can vary depending on the brand, materials used, and additional components included such as gaskets or rings. Set yourself a budget before starting your research so you can narrow down your options without overspending.

Installation Process

To achieve optimal performance from your big bore kit, proper installation is crucial. If you’re not confident in doing it yourself, it’s best to have it installed by a professional mechanic who has experience with big bore kits.

Maintenance

A bigger engine means more power, but it also means more maintenance. Make sure to follow the manufacturer’s instructions on maintenance schedules and procedures to keep your bike running smoothly after installing the big bore kit.

In Conclusion

A Yz 85 big bore kit is an excellent investment for riders looking to take their bike’s performance to new heights. Keep in mind all factors mentioned above when choosing the right kit for your needs and budget. With proper installation and maintenance, you’ll notice a significant improvement in your bike’s power and performance on the track or trails.
