okay, i had to reply to this one. i personally have run mine twice. i have never drag raced any bike with a hydraulic clutch and was pretty nervous. (tried on the street earlier in the day to launch, couldn't do it) so, i did'nt do any burnouts, stock off the floor. babied it out of the hole (went 2.09 short time) rolled on the throttle after the sixty foot mark and then let her rip. i went a 10:30 @ 140 mph. once again, no burnout, no lowering, no lengthening of the swing arm. stock off the floor down to the air pressure. also, babied it out of the hole really easy. that's rather impressive for a stock bike if you ask me.
by the way, i am 5'11" tall and weigh 190 naked (like you really needed to know that) so, with all my gear on, i figure around 220. hope this helps.
