Title: KFX400 Help Post by: LakeMaryKid on January 14, 2007, 05:47:24 PM 2003 KFX 400, been sitting awhile. Changed the oil, oil fitler, sparkplug and battery. Go to crank it and itll start for a few seconds then die sometimes. Most of the time itll just crank and turn over. You give it gas while idling and it will die. Choke on and sometimes off. Fresh new 93 octane gas. Carb gummed up? There is spark. Need some help dont know much about the z400/kfx400. Also the muffler is gutted.

Clean them with carb cleaner and take a piece of wire or a paper clip and clean the holes in the pilot jet really well. Also clean the float needle and seat.
