Well, yours seems to perform like mine. I'll let you know in a few days whether with the new gearing, exhaust, etc., what mine does. From what others have reported, our performance and mpg are under par, so I'm trying to figure out what that's about. The speedos are way out of whack anyway, and with my accurate digital speedo, my top speed was 76mph, @82 indicated, and others have reported top speeds pushing 90 and mpg in the 70 range indicated.
