Just rolling the throttle on slowly and fully in first gear will bring it up fine once you get past 8-9k RPM. I spent 2 months doing this a little bit at a time just to be sure as not to add my name to the ohh s%*t group. I would suggest the slow approach with any bike. I would NOT recommend snapping it open or rolling off and on hard until you have tons of experience doing it the slow way. Besides, it's a lot easier on the drive train (chain, tranny, etc.) that way, if you care about those sorts of things. While I am NOT the wheelie king by any means I am also NOT the "skid on my ass and watch my bike bounce down the street master" either.
Be careful,
