. This is my plug at idle to break in my 4mil crank and 65.50 piston. I also got v force 4 billet cross tube intake K&n pods 36:1 93gas. Mains are 310 and pilot30 and air fuel screw 2 out. Waiting for my 27.5 pilots come in the mall today. Just wondering if my plug looks alright. Going to do a plug chop soon. Should I run my ratio 40:1. Thanks guys
