There's a way to eliminate starter gear grinding altogether, but it involves installing a magnetic solenoid inline with the battery cable. Push the foot pedal all the way down to engage the gear, then push a button to trigger the solenoid switch and spin the starter motor. It also adds another level of "anti-theft" protection.
