I have a interesting complaint with this bike. When doing 50ish mph in 6th gear leaving a corner (yes you could drop a gear) and you whack the throttle open to accelerate...It does not lurch forward. It acts as if you rolled the throttle on slowly or the clutch is slipping slightly.... Could this be the second butterfly opening slowly? So when you really rip open the throttle fast that the second butterfly is slow responding and smoothes out the power? Is that its purpose?
