Why I Chose to Install a Big Bore Kit on My Yz 85

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

First and foremost, installing a big bore kit on my Yz 85 significantly increased its power and torque. With the bigger piston and cylinder, my bike now has a larger displacement which translates into more power. This has greatly improved its acceleration and top speed, making it much more fun to ride on trails or tracks.

Another reason why a big bore kit is necessary for an Yz 85 is because it helps in prolonging the engine’s lifespan. With the stock setup, the engine is constantly working hard to produce power which can lead to wear and tear over time. However, with a big bore kit, the engine doesn’t have to work as hard to produce the same amount of power. This reduces stress on the engine and can potentially increase its lifespan.

In this buying guide, I will share my personal experience and provide valuable information to help you make an informed decision.

What is a Big Bore Kit?

A big bore kit is an aftermarket upgrade that increases the displacement of your engine, resulting in more power and torque. It typically includes a larger cylinder, piston, and gasket set that replace the stock components. In the case of a Yz 85, it can increase the engine size from 85cc to 105cc or even more.

Why Should You Consider a Big Bore Kit for Your Yz 85?

If you’re looking to take your riding to the next level, a big bore kit can give you the edge you need. The increased displacement means more power and torque, allowing you to accelerate faster and tackle tougher terrains with ease. It also improves overall engine performance and durability.

Things to Consider Before Buying

  • Budget: A big bore kit can range from $200-$500 depending on the brand and features. Set a budget beforehand so that you don’t end up overspending.
  • Compatibility: Not all big bore kits are compatible with every bike model. Make sure to check if the kit is specifically designed for your Yz 85 before making a purchase.
  • Brand Reputation: Do some research on different brands and read reviews from other riders to ensure you are buying from a reputable company that offers good quality products.
  • Horsepower Gain: Different big bore kits offer different levels of horsepower gain. Consider how much power you want or need before choosing a kit.

Benefits of Using a Big Bore Kit on Your Yz 85

  • Increase in Power: As mentioned earlier, a big bore kit provides significant horsepower gain, giving your bike an extra boost of power.
  • Better Performance: With increased power comes better performance. You will notice smoother acceleration, improved throttle response, and better overall handling with a big bore kit installed on your Yz 85.
  • Durability: The larger cylinder in a big bore kit allows for better cooling, which can increase engine longevity and reduce wear and tear on internal components.

Tips for Installation

If you have some mechanical knowledge and experience working on bikes, installing a big bore kit should not be too difficult. However, if this is your first time attempting such an upgrade, it’s best to seek professional help to avoid any potential damage or complications.

  • Gather All Necessary Parts: Make sure you have all the necessary tools and parts required for installation before starting the process.
  • Cleanliness is Key: Ensure that all parts are clean before installation as even small pieces of dirt or debris can cause issues with performance later on.

In Conclusion

A big bore kit is an excellent investment for those looking to enhance their Yz 85’s performance without breaking the bank.
