    Recently purchased and replaced factory crank pulley with the kartboy pulley and I definitely see the difference. Acceleration is a lot quicker due to the weight difference in pulleys. For $95, easiest and cheapest mod you could do without needing a tune and certainly well worth it. Thanks to Subispeed for the air freshener and Laffy Taffy.
