READING SPARK PLUGS

Post by Brickyard » Wed Dec 16, 2015 9:27 pm

I've recently replaced a bad and broken coil with a working one, used LM's tuning recipe, gave the bike a few laps around the block, bike seemed to run fine, and pulled the plugs. I've always read the plugs should have a nice brown color, but haven't been able to find photos.

Am i running to lean, or do these spark plugs look good? Mixture screws are about 1 1/8-1 1/4 out.
