As an experienced motocross rider, I understand the importance of having a powerful and reliable bike on the track. That’s why I decided to install a Yamaha YZ85 big bore kit on my bike. And let me tell you, it was one of the best decisions I’ve ever made.

Firstly, the big bore kit increases the displacement of the engine, resulting in a significant boost in power and torque. This means better acceleration off the line and more top-end speed, giving me an edge over my competitors. It also adds more overall horsepower, making it easier to clear jumps and tackle tough terrain.

Apart from the performance benefits, this upgrade also improves the overall durability of my bike. The larger piston and cylinder increase the surface area for combustion, reducing stress on individual components. As a result, I’ve noticed less wear and tear on my engine and have had to replace parts less frequently.

One thing to keep in mind is that installing a big bore kit requires proper tuning of carburetors and fuel injection systems. But once dialed in correctly, it can significantly improve fuel efficiency as well. So not only am I getting more power out of my bike, but I’m also saving money on gas.

In conclusion, the Yamaha YZ85 big bore kit
