Yeah, you could cut a few cooling holes in the front & rear windscreen to get more airflow over the engine...

This is what i did with my Thunder Tiger TS-4...

YES!! your supposed to. Not only does this allow your engine to cool, it lets cool air into your air filter. Cooler air is more dence = more power.
I took it one step father and relocated my air filter to the cooler side of the car for more power!

I wouldnt like to have my filter there right behind the tire in front of the front tire would be better
