*Kawasaki kfx 400*

Adult M (30)
So I recently bought my first quad. I did A oil change, new battery, spark plug and took it to the mountains in arizona. I had some trouble with idol probably due to ekevation but thought what ever ill go back to pbx and clean the carburetor.. Now keep in mind I've never cleaned a carb but I watched a step by step tutorial on it pulled out the 3 jets sprayer everything with carb cleaner and reassembled. When I went to start it up it wouldn't turn over so I messed with idol.. Finally after 15 minutes got it to start but then within a minute of running it would die.. again 15 20 minutes get it started and it would die. My question is did I mess up idol and thats why its not starting? Or is it carburetor? I also am curious on if any one has manufacturers manual and knows what specifications are on idol to dial it in... I know I'm a total noob... Appreciate any help 🙏

 

Welcome to the forums.

Check the vent line coming out of the gas cap for kinks or clogs. Hope it something simple.

 

Yeah I'm assuming I messed with idol too much. It was running good before I cleaned carb fired right up.. Ill check vent line either way though man thanks for response 🙏

 

Never mess with the idle mixture screw. Adjust the idle speed screw to give a smooth low idle speed, but the mixture screw should be left alone unless extensive tuning has been done or you are riding at extreme elevations all the time. My guess is, if you couldn't get it to start after cleaning the carb, you put it back together wrongly. The on-line parts suppliers show exploded views of how the carb should go together https://www.kawasakipartshouse.com/o.../carburetor-a1 Don't know about Kawasaki manuals but Honda ones just say "do not alter the idle mixture screw".

 

Thanks for response man.. I definitely put it back the same way I took it apart. Literally pulley out 3 jets sprayed everything with carb cleaner and put back together. Didn't touch the float as it was already fairly clean. I got bike to fire up a few times here and there but dued every time I let off throttle. Before I touched carb it fired right up. Not sure what to do, when I put back together it wouldn't start until I messed with idle, but now I know for sure my idol is off. I was hoping to get Intel on factory carb settings start there and then proceed further need be?

 

Only Kawasaki book I have is for the Lakota, it states 2.25 turns out on the idle mixture screw.
