Tuning the expansion chamber on my motorized bike. Adjusting the header pipe length 6" was too long, 3" was pretty close but 1.5" is just right! I now have power all the way through the power band, cruise at 33mph, 35mph level ground (WOT- wide open throttle) and 38mph down hill!
Just don't wear shorts while riding these death machines. Burned two spots on my leg.
