I GPSed it today. I'd say 36mph is the average, was probably doing 28mph before with the open air filter but stock exhaust. On some flats I actually hit 38mph but I think I had a tail wind. I also got down a hill at 40 and once I hit the flat again it held it.
It's worth mentioning that I am 6'3" and 250lbs. I'm pretty happy with the results and would like to try taller gearing, a velocity stack and a bigger jet. Also those BMX pegs.
Ryan, on the pegs, you just used the frame bolt and nut to hold them in? That is what it looks like and it seems that would work well.
That fork set up is pretty sweet but I was really hoping there was something out there that would drop right into the current steering stem with out all of the fabrication. That might be a next year project. It seems to me it would make sense to find a front end with disc brakes already included, wheel and all if possible if I'm going to go to that much trouble to get it to fit.
Either way, I appreciate all the help. This bike is way too much fun in a different way than my track bike and ducati. I love that everything is so cheap for it too.
