dogboystoy Posted August 28, 2007 Report Posted August 28, 2007 Has anyone used the copperhead CDI from Velocity devices? I read some good reviews on it, so I went for it. Since I am poutting 27" tires on my grizzly (increase 2"), I heard you loose some low end, since I am putting on Mudzillas and they are a heavy tire, I think I will need all of the horsepower I can muster. http://www.rmstator.com/index.php/ATV/Yama...rizzly_660/1789 I did get the programming kit, so I can update the firmware and change the mapping when needed. Anyway, has anyone had good luck with this? I am suprised that I didnt see one for the banshee by the same company. Quote
