Taller tires cause extra drag on the drive system, and the wet clutch is the slippage mechanism between the engine and the power to the tire patch to the ground.
Raising the pulley ratio but machining will make pulling much easier on your wet clutch, and overcome the extra drag from taller tires. Not absolutely needed but will damn sure be appreciated by you and the wet clutch.
As for blowing the cobs out, hell yes! This should be in the owners manual as a daily requirement for a happy grizz!
