I hear that there are some re-charging issues with underdriven or smaller diameter pulleys. The economical alternative would be the lightened, but not underdriven, crankshaft pulley. The price ranges from $90-$150 and they can be a couple pounds lighter, but the same diameter which also lets you keep the stock belts, because the underdriven pulleys by nature will need a new set of belts.

no issues with mine. been almost a year. they do come with new belts.
