Set the carb a little leaner, and put it back on.

I've noticed that the filter cover is restrictive. You could drill some holes on the back face of the cover. Also Spooky Tooth sells a unifilter that'll give it more air.

This is like asking if the bike would run better with a velocity stack, if it works on car Individual throttle bodies then why wouldnt it help make more power on a single carb?

I have the stock black plastic air breather and I drilled four holes in the area around the mounting screws. I wasn't correcting a problem, however I do feel a difference.

Not exactly...he's asking if running with the right mixture and no air filter is a good idea..... it isn't.
Any engine will run better with a less restrictive intake or exhaust if it is tuned correctly.

But would a velocity stack improve the perfomance of these engines?
