The Need for a Big Bore Kit on Yz85

As an avid rider and owner of a Yamaha Yz85, I have come to realize the importance of having a big bore kit installed on my bike. The stock engine displacement of the Yz85 is 85cc, which may seem sufficient for beginners or younger riders. However, as I progressed in my riding skills and started competing in more challenging races, I soon found that the stock power was not enough to keep up with my competitors.

The main reason why a big bore kit is necessary for the Yz85 is because it increases the engine displacement, resulting in a significant boost in power and torque. By increasing the size of the cylinder and piston, more air and fuel can be compressed inside the engine, leading to a stronger combustion and ultimately more power output. This is especially crucial for racers who need that extra push to overtake their opponents or conquer tough terrains.

Moreover, installing a big bore kit also improves the overall performance and reliability of the bike. With more displacement, the engine doesn’t have to work as hard to produce power, reducing stress on its components. This means that your Yz85 will have a longer lifespan and require less maintenance compared to running

My Buying Guide on ‘Big Bore Kit For Yz85’

Hello fellow riders! I know how important it is to get the most out of your Yz85 and that’s why I wanted to share my experience with purchasing a big bore kit for my bike. This guide will cover everything you need to know before making your purchase, from understanding what a big bore kit is to choosing the right one for your specific needs.

What is a Big Bore Kit?

A big bore kit is essentially an engine upgrade that increases the displacement of your bike’s engine. It involves replacing the stock cylinder and piston with larger ones, allowing for more air and fuel to be compressed and ignited, resulting in increased power and torque.

Why Upgrade?

The main reason riders choose to upgrade their Yz85 with a big bore kit is for more power. This can be particularly beneficial for those who ride in competitive races or simply want to have more fun on the trails. The increased power also means better acceleration, making it easier to tackle tough terrains.

Things to Consider

  • Bike Model: Not all big bore kits are compatible with every model of Yz85. Make sure you double check that the kit you are considering is specifically designed for your bike.
  • Budget: Big bore kits can range in price from a couple hundred dollars up to a few thousand. Set a budget before starting your search so you don’t overspend.
  • Riding Style: Consider how you primarily use your bike when choosing a big bore kit. If you mostly ride on tracks, you may want something with more horsepower, whereas if you do mostly trail riding, torque may be more important.
  • Brand Reputation: Research different brands and read reviews from other riders to ensure you are purchasing from a reputable company that produces quality products.

Tips for Installation

  • Hire a Professional: Unless you have experience working on engines, it’s best to have a professional mechanic install the big bore kit for you. This will ensure everything is done correctly and minimize any potential problems down the road.
  • New Parts: Along with the big bore kit itself, there are often other parts that need to be replaced or upgraded during installation such as gaskets and valves. Make sure these are included in your budget so there are no surprises later on.
  • Break-In Period: After installation, it’s important to follow the recommended break-in period given by the manufacturer. This typically involves avoiding high speeds or heavy loads for the first few hours of riding until the new parts have properly settled in.

In Conclusion

A big bore kit can be an exciting upgrade for any Yz85 rider looking for more power and performance. Just make sure to do thorough research before making your purchase and follow proper installation procedures for optimal results. Happy riding!
