I'm still snowed in so I can't go out and do my "seat of the pants dyno" ride I usually do after work like this and the suspense is killing me!
According to these graphs: (Procycle, I hope you don't mind, if you do just PM me and I'll clean up the post)



And



You should be seeing around 36 hp and 32 ft/lbs. when I uncorked my dr, and jetted it properly, (stock exhaust, cut-top air box, KNN filter) it felt like it ran crisper with more low end power. When I did the carb upgrade, that was the most noticeable increase in pep. It almost has that fuel injection, instant power feel. I recently did the hayabusa muffler upgrade, and I haven't been able to ride enough to pin point my jetting properly, so I can't comment on how much different that feels. The exhaust note is much better, I can tell you that!
