Drilling holes in the air filter box to improve the engines' breathing
will give more power. You will however need to adjust the main jet
dimension as well, since the improved air supply will lean the fuel
mixture considerably. If you don't, a seizure could be the result.
Also, the engine noise level will increase.

Goran.
