Are  you running a spark arrestor type of muffler?  If so remove the screen and make a pass down the street.

Are you running the air box lid?  If so remove it and make a pass down the street.

If you are not running the air box lid, remove the air filter element and make a pass down the street.

Currently setup with the Aaen pipe, no spark arrestor, and no air box lid.  Foam filter with an outer wear. 

Pull the filter and make a pass? Sounds interesting..
