Check the clutches for free movement. If one or them is binding, it will give you these symptoms.

it might be that your main clutch sping is weak and the clutch is closing to early before the motor is up to rpm therefor the motor doesnt get enough rpm to take off with out bogging I had the same prob

have you cleened your carbs recently?

but as somone else said it could definatly be the clutches.
what rpm doen it engage at,if you let off the trottle so slow down an bit then stand on it, what happens. what colours are your plugs.

does it sound like an engine bog or a drivetrain bog.

What happens when you let off the throttle, then hammer it again like eric phazer said? This can help us eliminate it being a jetting problem.
