GT250R efi

Agree, your plug-example looks about right.
About mine; this was after 1 hour “city”-driving, never above 6000 rpm, never above 1/2 throttle.
(mixture gets richer at wot, and higher rpm)
And…please delete the double-post, probably had a browser-glitch…

Old and grumpy,(?), have fairly wide engine & tuning experience, "restoring/resto-mod" on cars & mc, worked as electronic tech.
