Spark gap .. the answer from dynatek

[Guest]

I have a 1982 gs750 and installed new dynatek coils and ignition and was getting a variety of gap call outs when searching the forum so I decided to write dynatek. So I can contribute something instead of just taking I thought I would post the response.

Comments: I have a 1982 Suzuki gs750e that I installed your dyna S
ignition in as well as a pair of 3ohm coils. I am getting varied
instruction on some motorcycle forums on what I should gap my plugs at.
I have been told .26, .28 .31. Figured I would come to the experts. What
should I set the plug gaps to for this set up? Alex

Hello Alex.
While the engine would run well at many different plug gaps, I would suggest
.032" for the best performance.
Thank you,

Truth of the matter is it doesn't matter. Suzuki spec is .024 to .028. .032 is fine as well since those coils have a little more power than the stockers.

I'm putting Accels on my GS and the instructions that came with them says to set the gap at .035". Just FWIW.

I had a local motorcycle mechanic with more knowledge than me suggest .035 gap, claiming more flame propogation, for more complete burn.
I went back several years later, he said I never said that, eventhough I'd be running on that suggestion for awhile.

Now, I'm just buying the NGK plugs and installing them. I do have Dyna-S and Green Dyna 3ohm coils and all seems well aside from all my other engine issues.
