Supposed to "increase horsepower"...... Sounds like snake oil to to me. But here's the thing..... It was in.... "Motorcyclist" magazine I believe, where I got the link. It wasn't the classified or sales section, but rather "Best gifts for under $50" I think........ It's the issue where they test all the new liter bikes head to head. Has the ending result of #1 Kaw, #2 Yam.......
