3 ohm or 7 ohm coils

Post by RMBLOldwinger » Sat Nov 18, 2017 7:02 pm



I did not see a current thread on this although I have seen a lot of discussion on coils in the past. What I have not seen is the definitive answer to the coils on the 1983 GL1100. I understand that it does not have a pure CDI ignition, and it seems therefore that the 3 ohm coils should work on it. However 7 ohm coils are recommended for CDI ignition. Am I correct on the 3 ohm coils? Thanks so much for all the great information on this site!

Don't know what the resistance of the OE coils is but it is definitely not CDI ignition, you find that mostly on dirt bikes, ATVs, outdoor power equipment and the like.

Thanks for the response! I was about 90% sure which way to go, but I was just trying to nail it down. Short version is that I got a set of 3 ohm Dyna coils and they worked great. On a not so happy note, I got so wrapped up in the coils and the Weber carb conversion that I put off changing cam belts too long. I kept saying, "as soon as I get it sorted out, I will put new belts on it". I now have a fresh motor on the way and I will be putting new belts on it as soon as it is off the freight truck. I should have known better. Once again, I really appreciate the unbelievable amount of knowledge on this site and the willingness of the members to share.

Oh no. I know the temptation is so strong, "oh it will be fine, I'll change them soon...."

How bad was it? Did you hole the pistons? Any pictures of it?

Dyna makes a DC6-4 (2 coils in 1 with twin towers ) that I have been looking at for a coil change. Anyone out there tried this setup?
