Default Plug color feedback

I took a 4 mile ride through all range of rpm's, no top speed plug chop for 20 seconds but I took the plug off and heres what it reads. Still is 4 stroking at bottom end, top end is OK but top speed is only about 26mph (with a 44 tooth, and still in break in) but I expect more from it when broken in hopefully? This motor is not stock. Tell me what you think. Running opti-2 at 100:1

Plug is black, not wet black though but has a pretty dark color
