I agree with carlsoti...it does sound logical but I havent tried it myself(I'm running a slipper clutch). Are you using a slipper clutch or just using the clutch lever? I know you said the bike is basically stock but just thought I'd ask. If your just trying to induce the rear coming around, try getting on the front brake a little harder and feeding the clutch out until the bike starts reving upand try to maintain a certain rpm a little shy of the midrange. Eventually you'll get results. Is it a race bike or street set-up?
