Electronic Ignition Model Differences 09 Sep 2021 05:32 #855039

Matt bx Topic Author Offline Sustaining Member Posts: 38 Thank you received: 8	Hello, can anyone tell me the differences between the J model Electronic ignition and ZN1100/GPZ? I was going to buy a Dyna S system for my 81 LTD but I have a ZN1100 crank. I remembered the ignition and crank end was different then the J model but the J model rotor and plate did bolt up. Dyna does not list the GPZ or ZN1100 as compatible with the Dyna S DS2-1.

The GPZ/ZX1100 IC-igniter had an extra electronic ignition advance circuit onboard.

The igniter electronic box did the advancer job. My 1975 Z 1 B 900 Project www.kzrider.com/forum/11-projects/605133...ears-deep-sleep-mode Attachments:
