How to set the timing on a Motoplat equipped engine. 135cc Komet B BOMB w 56mm stroke.

KOMET K30 B BOMB TIMING. With a big stroke crank vs smaller stroke you can't put as much timing in shorter stroke engine. We set our 56 mm stroke engines at .090" to .104"BTDC. Smaller stroke engines should be in the .080" to max .090" range on a typical 48mm stroke engine depending on application. You can find the adapter for the indicator at https://ladspecialties.com/
