What coil rating for Dyna S

#1 PostAuthor: Garn 1 » Thu Feb 26, 2015 3:25 am

I'm wondering, what is the optimum coil rating for a Kawaski Z1 fitted with DynaS?.
I seem to remember that DynaS recommends coils to be 3 ohm or less.
I think standard Z1 coils are 4 ohm across the primary windings.
I have access to a pair of 3 or 4 ohm coils.
Any thoughts on the topic appreciated.

I got in a mess with all this!
In the end I emailed Dyna and they told me to use Green ones (3ohm) in conjunction with the Dyna S system, I originally bought grey ones and then black ones, managed to change the black to the green so all good :D

3ohms minimum resisistance with the the Dyna 'S'.
You can run higher but not lower.

Do NOT run less than 3 ohms with DYNA S.

I used 2.2 ohms (grey) dyna coils on my Harris :roll: and one of them cracked/melted after 50 miles :cry: so I fitted 3 ohms and no prbs since, so it have to put it down to the wrong coil rating.

2.2 ohms are okay with DYNA 2000 :wink:
