just rev the piss out of it and drop the clutch wide open!!! that's what everyone else does! people kill me sometimes with what I read and see . there is A SUCH THING CALLED SLIPPING THE CLUTCH... controls wheel speed , spin, and also keep you from just digging a hole where you launch. nothing funnier then seeing people who consistently lose come back and try and leave even harder the second time. my clutch is never fully out until Im moving and in 2nd gear.
