I don't disagree with John. One question to you, is the fuel valve shut off and is it still leaking? The reason I ask is with my sons 2001 KDX200, it would leak with the fuel valve shut off. As John said I went through the routine to set the float level. This didn't cure it, so I did it again. Well the third time I purchased a new needle and the float gage tool from Kawasaki. It still leaked. Finally I purchase the replacement seal for the fuel shut off valve. The leak stopped. I wanted to think that using a new needle and the float gage tool, following the guidelines provide to set the float level it would have cured the problem. It didn't and people can still say the float is set wrong since it would drip gas out the over flow. I won't argue, because it's the most common reason. All I know is that when I replaced the seal in the fuel shut off, the problem went away.
