Are you running original coils? If so, they should measure about 3.8 ohms on the primary side and about 13,000 ohms from plug wire to plug wire.

Most Z1 riders upgraded to a Dyna S2 system. That would be the green Dyna coils and the recommended pickup for a Z1. Just guessing at the cost, but around $250.

I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.
