019-10045 Compu-Fire replacement starter pinion gear for Harley-Davidson

Designed for later Evolution and early Twin Cam engines, this 10-tooth starter pinion gear is the correct replacement for Compu-Fire starter ring gear conversion kits 538430 and 538431. It fits 1994 to 2006 Big Twin models, though it excludes the 2006 Dyna. When your starter engagement starts to feel less than positive, replacing the pinion gear is a smart maintenance move. This gear is built to handle the high torque loads of a modified Harley engine, providing a crisp and reliable connection every time you hit the start button. It is sold individually and is an essential service part for anyone running a Compu-Fire ring gear conversion on their drivetrain.
