ExactFit High Voltage Ignition Coils

Post by Mustang505 »

Hi Guys
good to have the site up and running again - thanks
has anyone tried these on a sport or paso and they work? Currently from Cycleworks and listed as working on 91-99 750 & 900ss.
Or any of the Dyna Green or Black coils at Bevelheaven?
My original coils I suspect (23years old) are tired and the plug caps very tired - front cylinder lead fell off during a classic race this weekend as i was trying to close in a XS1100!!
So I'm looking to replace the whole set up - coils and leads - any sugestions?
Cheers
Clive

If you have the Digiplex ignition, then it has 4 ohm coils. The rest of the common world uses 3 and 5 ohm coils. Dyna recommends the 3 ohm, as that's the kit for the SS bikes. (Green coils) I have them on my Sport. If you feel nervous about the mismatch, get some big honking 1 ohm resistors, and put them in line, which is what I did 5 years ago now. Works fine. Coils are replacealbe items anyway, and 20 + years is enough for a motorcycle coil.

with the dynacoils either the 3 or 5 ohm will work. Make sure you get the single output coils. DC3-1 or DC10-1

DC3-1 is the 3 ohm coil,you will need two of these and a bracket to mount them

DC10-1 is the 5 ohm,you will need two of these and a bracket to mount them

Bevel Heaven sells a nice bracket kit that works very well or you can make your own


with any coil replacement polarity is very important to the operation of the coil and the life of your module

I`ve been running aftermarket coils with 2.7 ohms resistance for years (definetely not recommended as these should be used with the CDI unit of the same manufacturer) but nothing ever happened, the original CDIs are just fine. I know several guys that use the Dyna green for years with no probs.

I bought the kit and fitted - i guess that's why it's called exactfit - fits the sport perfect :) , no need for any brackets etc. Biggest job is to cut the horz cyl lead to fit! Also the spark is at least 4 times larger than what i was getting.
