2stroke sparkplug "reading" after plug chops?

This was from last year when all I had was the wet pipe. It still felt a little rich to me, but what do you guys think? FYI, There is fogging oil all over them. I put the new higher psi head on this year and the plugs got real platinum looking. Had to fatten up the top a bit.

you should try to run your rear cylinder richer because there is more load on the rear cylinder because it drives the coupler.

What does the front cylinder drive?:thinking:
