Not sure if you know or not, but you used to be able to buy the touch-up paint from Kawasaki (Part number S56019..... for spray can and T56019.... for a touch-up stick. Last digits refer to the paint code). The only problem I have found in the past is that when the bikes are painted at the factory Kawasaki use a primer, so when you try to touch it up without it, it quite often ends up being a bit lighter in colour. Hopefully some can help you more than this, but it is a start??
