Larry,
Unless your mechanic friend is riding a Ducati or one of the Japanese sportbikes that now come from the factory with a "slipper-clutch" installed in it, I'd still(as NIbiker advised here) blip the throttle to match engine-speed with wheel-speed. Without blipping you are putting needless torque on your whole drivetrain, including the gearbox, chain, and cush drive.
