What he said. The gear drive does absolutely nothing for a typical motor. Stick with the timing chain and get an adjustable one if you're going to replace the stock unit. If you can afford it, go timing belt. I've got a belt drive with a crank trigger setup, and the timing is dead nuts solid, stable, does not move whether its at idle or at 7000 rpm. A gear drive's not worth the noise price of the steel they're made of IMO.
