All mods are in sig. I started out with a 158. I thought that would be a little rich. I did a WOT 1st-6th plug chop with a brand new plug. I got it back in the garage and chopped the threads off it. It was a light gray. Really lean. I put the air tester on it and found a leak at the exhaust flange. I fixed the leak and it held 7lbs for 30 min. I then put in a 162 and it barely changed the color on the plug. This motor is fresh from ken occonor and doesn't even have an hour on it.
I ride at sea level. Piliot jet is 42 and a cel needle. Does the needle affect the plug shop at all? I just don't understand why I'm not getting to the cardboard brown color. At this rate I will have a 170 jet. Just doesnt seem right. Any help is appreciated.
