Has anyone tried this? I was reading an article in American Iron. Boyesen makes this Power X-Wing. They installed it in a 1200 sportster. And the results were pretty good. The Stock motor put out 65 horsepower and 73 Torque. After they installed the X-Wing it put our 73 horsepower and 82 Torque.
Seems pretty impressive for only 130.00 bucks.
I don't know of any mods for that price that will give you that kinda gain.
Has anyone tried this on a larger cubic inch motor. If so, did you see any noticeable improvements?
Or do you think it just another gimmick.
