What Is a Big Bore Kit? A big bore kit is an aftermarket modification that replaces the stock cylinder and piston in a motorcycle engine with a larger one.
This increases the engine displacement, resulting in increased power and torque. Big bore kits are typically used on larger displacement engines, but can be used on smaller engines as well.
The larger displacement typically results in improved acceleration, top speed, and overall power.
Big bore kits are a great way to increase the power potential of your motorcycle. They can be used to increase horsepower or torque, depending on your needs.
Are you looking to get more horsepower out of your engine? If so, then you’ve likely heard of a Big Bore kit.
This powerful piece of equipment can make a huge difference in the performance of your engine, but what exactly is it?
In this blog post, we’ll discuss what Big Bore kits do, why you might want to consider one for your bike, and how to install one properly.
What Is A Big Bore Kit?
A big bore kit is a set of components used to increase the displacement of an engine. These kits range in size from 50 – 250cc and are most commonly used for two-stroke engines such as those found in dirt bikes and ATVs.
Installing a big bore kit can result in significant power gains, improved torque, and quicker acceleration.
The larger bore size also increases the amount of fuel and air that can be forced into the combustion chamber, resulting in an increase in horsepower.
In order to install a big bore kit, you will need a few basic tools such as wrenches, screwdrivers, and a torque wrench. You will also need to have the necessary parts such as a piston, cylinder head, gaskets, and seals.
Once all the components are in place, you can begin the installation process. This will involve removing the engine’s original cylinder head and piston before fitting the new ones.
Next, you’ll need to make sure all the gaskets are properly seated and that all connections are securely tightened.
Finally, you’ll need to calibrate your engine for optimal performance. With a big bore kit installed, your engine will be ready to take on any challenge you throw its way!
How A Big Bore Kit Works?
It’s important to understand the basics of how a big bore kit works and what components are necessary for proper installation.
The cylinder is the most important component of a big bore kit and is usually made from aluminum or cast iron.
It contains larger bores than standard cylinders, allowing more fuel/air mixture to enter the combustion chamber, resulting in increased power output.
The piston is also larger than standard and has a thicker skirt to reduce friction and heat buildup.
Additionally, a valve head replacement is necessary to ensure that the larger cylinder can accommodate the increased volume of fuel/air mixture.
Once all of these components are installed, they must be tuned to ensure that the engine runs efficiently and safely.
If done correctly, a big bore kit can give your bike a major performance boost, providing you with an unforgettable riding experience.
How Do You Install A Big Bore Kit On Your Motorcycle?
To install a big bore kit, you’ll need to gather the right tools and parts. You’ll need a torque wrench, Allen wrenches, a gasket set, a set of piston ring compressor pliers, and a cylinder honing tool.
Once you have the tools and parts ready, you can start the installation process.
First, you’ll need to drain the oil from the engine and remove the cylinder head. Once that is done, you can remove the cylinders from the engine.
Then, you can begin to install the big bore kit by fitting the new cylinder sleeves into the engine and tightening them with the torque wrench.
Next, you’ll need to fit the new pistons into the cylinders, make sure they are correctly seated and then use the piston ring compressor pliers to fit them into place.
After that, you’ll need to hone the cylinders with the cylinder honing tool so that they are perfectly round.
Finally, you can reattach the cylinder head and refill the oil before starting up your motorcycle to test it out. With careful installation, your bike should now be running at higher performance levels with increased power.
How Do You Calibrate Your Motorcycle for Optimal Performance?
Once your big bore kit is installed and calibrated, it’s important to keep it running at its best. To do this, you’ll need to regularly check the engine’s performance and calibrate it as needed.
This process involves measuring the engine’s horsepower and torque and adjusting the settings accordingly.
If done correctly, your bike will be running at its optimum performance levels and you’ll be able to take on any challenge that comes your way.

Drawbacks Of Using A Big Bore Kit?
When considering whether or not to install a big bore kit on your vehicle, it’s important to be aware of the potential drawbacks.
Big bore kits can increase the power of your engine, but they can also put extra strain on your car’s components.
This can lead to faster wear and tear on the engine, resulting in more frequent maintenance and repair costs.
Additionally, it’s possible for the kit to put too much stress on the engine, leading to poor performance or even a breakdown.
How Much Horsepower Does A Big Bore Kit Add?
The power that a big bore kit will add to your engine depends on the size and type of kit that you install. Generally, kits that increase the horsepower range from around 100 to 150 horsepower.
If you’re looking for more power, a bigger kit will be the best option for you. However, if you’re only looking for an increase in performance modestly, a smaller kit may be better suited for your needs.
How Much Torque Does A Big Bore Kit Add?
Again, the torque added by a big bore kit depends on a variety of factors, including the type of kit that you choose and your engine’s specifications.
Generally speaking, kits that increase the torque range from around 10 to 30 ft-lbs.
Do I Need A Big Bore Kit?
Big bore kits are designed to increase the displacement of your engine, allowing for more power and torque. However, there are some important factors to consider before you decide to buy one.
First, you need to decide if your bike needs more power or if it just needs some tuning. If it just needs some tuning, then a big bore kit won’t be necessary.
Next, you need to make sure that the kit is compatible with your bike and its components. Finally, you should also consider the cost of the kit and whether or not it fits into your budget.
Taking all of these factors into consideration can help you determine if a big bore kit is right for your bike.
