For every knight, refitting a motorcycle may be a way to express his personality and show himself. It is also a new operating table. After all, the motorcycles produced on the assembly line are too lack of individuality. You can increase the "appearance" to make it look different from other people's cars, and increase the "energy" to make the car drive at the speed you want. In order to avoid unnecessary misconceptions of motorcycle users in the process of refitting, I'd like to share with you the following: where can motorcycle refitting be changed, where can it not be changed, how can it make the motorcycle faster, and where can it touch the law

1. If the carburetor is refitted, the intake manifold needs to be replaced only when the diameter is more than 24mm, while if the carburetor is refitted with the diameter of 20mm or 22mm, the intake manifold does not need to be replaced.

2. The bigger the carburetor, the better. The bigger the carburetor, the more likely it is to cause excessive air intake, which will not only cost fuel but also affect performance. Generally, for a jog, it is enough to refit a 47mm (70cc) cylinder with a 24mm carburetor.
