Has anyone dyno bike??

[Cutty]

Has anyone put their bike on a dyno before changing pipes and than after muffler change to see HP and torque values? Just wondering if the 2 cylinder mufflers exhaust waves where any different than the 4 cylinder flow.

I know Barron's has. They were designing the nasty boy when I build their dyno room. I had the actual # but lost them in a computer crash. The Road King pipes with carb adjustments did better than stock; Nasty Boys with big air kit and re-jet made big HP but bad MPG. They had a kit at one time but don't know if is still available. I saw some real tire burners while I was there including turbos. Ride safe Rod
