with 600 miles on the bike, I dynoed 101.3 @ 12,500. I now have almost 4K on the odometer, and am going to dyno it again soon before I get the pipe, pcIII and what ever else I can find. Mine is still stock with the exception of the air valve removed and the airbox sealed. I will post when I get it done, hopefully this week. I also got a spare stock pipe that I cut down about 5" and mostly gutted, I might run once with that to see if there is any gains or loss. I can say that it is loud! and obnoxious.
