2nd improvement: INCREASE THE AIR FLOW

Because regulations…CF Motos, like many other brands, has an Air intake silencer and it’s blocking the air come fast enough in the air box.

When opening the air box cover, the wheel horsepower usually pops up by 2hp. This is caused because the majority of users like very quiet engines and manufacturers have tight regulations. But we who like braaap and roar, it’s bad!

The easiest way is just remove the air box cover and cut a big hole in it (look at the pictures bellow ↓) and let the air flow evenly inside the air box. You will definitely notice different at your engine behaviour! And don’t worry! This will only affect positivity in your fuel consumption, more power and torque is always good!
