i have a crane hi4 single fire race ignition and a crane dual fire coil can i run both together as i already have the dual fire coil given to me

 

I think a better question, to you, would be why? The HI-4 system is designed to fire each cyl. by itself. The other system fires both cyl. each time either cyl. should fire. To answer your question-
I am not sure if putting the 2 'signal' wires togetheron a standard coil would not harm the HI-4.
The best I can do is give you Crane's tech line # 904-258-6174

 

There may also be a switch to change the mode of the module to dual fire.
the Mallory I am using has this capability.
The single fire coils are expensive, cost me about a hundred dollars. Ouch!

 

There are 2 switches on a HI-4- top switch is for advance curve and the other is kick/electric start.

 

Bummer! {not being able to change modes}
Maybe you could find someone to sell the coil you have and get the correct one for your bike?
I would guess that you are going to need the single fire coil for the system to work.

 

No - No - No
