Does anyone know the part# for the Bosch 6500 RPM rev-limiting rotor buttons for a 009? Anyone know a source of them?

don't know the part#'s, but aircooled.net has them: www.aircooled.net/new-bin/viewproductdetail.php

vvds or mickmotors probably have these too, i'd try them first.

also, these are the resistive type and can not be used with a cdi.
if you have high energy ignition or cdi, i think there's a centrifugal one available, (bosch as well).
