    Question, after you upgraded your ignition and coil did you find it necessary to open the spark plug gap?

    It also depends on the air-fuel mixture; the leaner you go, the more gap you add, the richer you go, the less gap, both changes are over stock. And, of course, it's trial and error, I would recommend a few sets of used plugs, all gapped over or under stock as the case may be for your engine and when you've found a good-performing gap, put a new set in, gapped .002" smaller than that gap on the used plugs.

    Do you have pics of your plugs?

    No, I don't even have my chero yet. There were covid related delays in the shipping. But it's finally in transit. I'm just knowledge gathering right now.
