Glad to hear someone say that after actually seing the plugs.

If it was too lean the whole plug surface (inside of the head) would be white, yours might be a little lean, but it is no where near as bad as some I have seen (including mine). The white material you see is actually metal partials from your piston, rings, and cylinder walls.

With 99.9% confidence Champion makes Harley's plugs. I think the Champion replacement is RA8HC. Couple of bucks cheaper.

Your plugs are fine. If it was too lean they would be white with a glaze on them, sort of shiney.

As far as the popping, I installed the SE slip-ons on my Bob a few months and just a week or so ago did the stage 1 ac and map. I got a little pop on de-cel too that did not go away after ac and map. I am thinking there might be a minute gap between the clamp and the pipe/slip-on surfaces. I did use new clamps. HD said nothing about it after the map and service. A friend said they all pop a little???
