The Champion plugs got here this morning and I put them in Nana Chou. Drove her about 60 miles and so far so good.
The bottom of the NGK plugs are white. Does anyone here know what this means, and what adjustment do I need to do to Nana Chou?
OCR, the plugs look fine to me. Tan to grayish-white is normal. If anything maybe a little lean but most bikes are tuned to the lean side now. Also could be a little whiter from fuel additives. I think though that a person with your experience already knew the answer to the question before you asked it.
