i removed the stock plastic inlet cover to the stock air cleaner on my 79 cbx. it sounds better than before. does anyone know if you get a horsepower increase by removing the cover with the stock exhaust ?. it looks like the actual; nozzle area is restrictive on it, i imagine the main function was to reduce noise.

My experience was that it leaned out the mixture and keeps the motor from reving up to redline.

I forget the details, but this is discussed several times - have a look through the Carb posts.
