Default Re: Plug color feedback

Thanks Davezilla, I've actually already got the clip at the leanest position, still 4 strokes from 0-half throttle but it's tolerable, at least for break in. So now I have the clip at the leanest position, and I have a size 64 jet in it. Most people said to stay with the stock NT jet (size 70) until it was broken in, but riding it like that was not tolerable for me. So with this black plug color, should I down jet a bit more or just leave it as is until 200 miles? (currently has 20 miles on motor) Will running it rich like this not allow the rings to seat?
