Alright, I was have some starting trouble with my KFX, and so i got intouch with the tech guys at Kawasaki. They told me to screw the "idle/choke/enriching" screw all the way closed and then come 27 clicks out. They also said that their is a sensor on the quad that makes it not start unless the clutch or something is pulled in, and if it isn't working just right, this would make the quad not start or run right. And then he said that the Throttle Positioning Sensor may need to be reset. If y'all are having the starting problem still, just try the "choke" screw and if that doesn't work just take it down to your local dealer. You may be able to get it filed as a warranty claim.
