Read this plug !

Out of curiousity is anything obvious looking at this plug ? My guess is too much heat. It is a stock gap/heat range rapid fire that we put in just for break in. Thoughts?

I am not a pro plug reader, but we need to see the plug from another point of view. Its the white insulator on the center electrode that one looks at. It should have a slight color at some point down in the case.

From that angle, if the color rendition is true to life, it looks a bit on the lean side. JMHO

Looks pretty good, depending on miles. What does the insulator look like?

here is a very informative article with pics, which may give you more insight into timing/rich/lean spark plug reading.....at the very end, there is a link to "Plug Picture chart" that shows the condition of a variety of plugs and the most likely problem.
