Ram Air?

Or Bullshit? I wanted to try it out on my sportster. So I hacked up a Heavy Breather I had laying around and made up a radius. Welded it together and hand finished it. 

So did it work? I put it on the dyno before we went to the track and it was down about 7-8% through the powerband. I don't know if it was weather related, if the motor was stronger when it was fresh, or because I had the slick mounted.

The bike ran nearly identical ET and MPH as it did a month or two earlier, actually a touch faster at 11.29.

So I don't think it hurt, but didn't see a significant gain there. More testing next season....

(Actual ram air probably doesn't occur until higher MPH)
