The word bore up must be familiar to some people who have a hobby of modifying their motorbikes. This word sounds pretty cool and very technical. In this article, otomodify will explain about bore up, why many people do bore up and the risks involved in doing bore up.
What is bore up?
Bore up is a process or way to enlarge the diameter of the cylinder in a motorbike engine. The purpose of doing bore up is to increase the capacity of the combustion chamber or cc. With a larger space, the volume of fuel and air that enters will be greater. This makes the energy produced greater. So in short, bore up is an effort to improve motorbike performance.
Usually bore up is done by replacing the piston and cylinder block of the motorbike with a larger size. This process is of course carried out in a workshop that has experience in motorbike modification.
Why do many people do bore up?
The shortest and most concise reason is to make the motorbike faster. But of course every rider has their own reasons. Many riders do bore up because:
- More responsive traction: When riding a motorbike on an uphill road, the motorbike will be easier to control
- Participating in a counter or racing: Bore up makes the motorbike more competitive
- Personal satisfaction: There is a sense of pride when a motorbike that is modified by yourself has a more stable performance than the standard motorbike in general
However, bore up is not just about speed. Some people do bore up because the condition of the engine is worn out and at the same time replaced with a higher spec.
What is changed during a bore up?
Some of the main components of the engine will be replaced or adjusted when doing a bore up. Here are some components that are often replaced when doing a bore up on a motorbike:
- Piston: Replaced with a larger diameter so that it can fit the new cylinder
- Cylinder block: This part is enlarged or completely replaced to fit the new piston
- Carburetor or injection system: Replaced so that the fuel supply can match the new capacity
- CDI and ignition: So that the ignition can balance the larger fuel volume
- Exhaust: Sometimes adjusted so that the exhaust gas flow is smoother
All of these components must be arranged harmoniously and in balance. If one is not balanced, the engine will experience a decrease in performance. In addition to decreased performance, the motorbike will be more wasteful of fuel.
Risks of doing a bore up on a motorbike
Although basically a bore up is done to improve motorbike performance, incorrect application will cause damage and other problems. In doing a bore up, extra attention is needed so as not to damage the engine. Here are some of the risks of doing a bore up:
- The engine becomes hotter: This happens because combustion will be greater. Resulting in increased engine temperature
- More wasteful of fuel: Larger engine capacity means more fuel is needed
- Engine life can be shorter: Components will wear out quickly if the bored up motorbike is not properly maintained
- Not legal for daily use: If the engine capacity increases significantly, the data on the motorbike certificate will no longer match. This will be a problem.
Therefore, it is very important to understand bore up before doing it. Don't just follow the trend without knowing the risks and how to maintain it.
Safe tips for those of you who want to bore up
If you are sure about doing a bore up on your motorbike, here are some tips so that the bore upp process is safe and the results are more optimal and minimize the risk:
Choose a reasonable bore size: Don't immediately replace components with larger sizes. Start by replacing them with sizes that are still within the engine tolerance limit
- Use quality parts: Pistons, blocks, and other components must be from trusted brands.
- Consult a repair shop: Don't try to bore up yourself if you've never done it before.
- Reset the carburetor: This is very important and must be done. This is done to keep the performance balanced
- Regular maintenance: After doing a bore up on a motorbike, the engine requires more maintenance.
Conclusion
Bore up is one of the modifications that is quite popular among motorbike modification lovers. The goal is very clear, which is to improve performance. However, behind all that, keep in mind that there are risks from every action. If you still want to do a bore up and can't do it yourself or have never done it, you should ask an experienced workshop. Hopefully this article can be an initial guide for those of you who like to modify motorbikes, especially bore up modifications.
