CB/CL350 Dyna Coils 3 Ohms or Ohms

[alexmac]

I have decided to get some new coils for my bike. I am going with Dyna and am trying to decide between the 3 ohm (DC3-1) and the 5 ohm coils(DC10-1).

I will be using them with an electronic ignition. The instructions in the ignition kit say you can use 3 ohm coils with it.

What would be the advantage of using 3 ohm coils vs 5 ohm coils?

Check to see if you need a resistor for the 3 ohms. You need one on the cb750 to get the actual advantage of using the lower resitance coils

Hmm. I don't see any mention of a resistor... but it does say this:

"
For those who are running high-compression, high-RPM applications and wish to use aftermarket coils for maximum spark energy in competition applications, coils with primary resistance down to 3.0 ohms are permissible. Coils with 5.0 ohms primary resistance will work well for street applications, and have the benefit of drawing less current, running cooler, and stressing your bike’s charging system less."


I guess 5 ohms might be best. Aren't they larger than the 3 ohm? I am concerned about clearance under the tank.

No they are all physically the same size.
Well all the "normal" sized ones are, the mini coils are...mini
The 3ohm are green, 5 are black.
None of them are bolt on to a cb350. The stock mount needs to be modified a bit.

Good to know.

I went with the 5 ohm coils. I have seen some good ideas for mounting them around the net.
