B.T.W., you mentioned getting wrong/misguided info off the internet, have you gone to ninja250.org for maintenance documentation? That site has a very comprehensive "Technical and Repair Info" section. I guarantee you wouldn't have gotten the plugs wrong if you were reading ninja250.org directions.
I have gone to ninja250.org "Technical and Repair Info" section. That site has been extremely helpful! I've also downloaded the Service Manual and purchased the 2007 Supplement off of EBay to assist in the piston replacement.

I'm glad that amount of carbon is normal. I bought two used pistons that came very clean and most of the pics I've seen on the ninja boards seem a lot cleaner.
