have 87 600f1 would idle with choke clean carbs can't get any fuel to come out carbs won't idle when clean carbs two float's where stuck and bikes been sitting a long time and was not stored right any idea's on what to do or just getting sum used one's the best thing to do these carb's have striped screws and very dirty sorry for long sentence not good with pc

 

first and foremost, download the haynes service manual. It can be found in the forum.

Second, Give your carbs a GOOD Cleaning (without seperating them in the rack). Meaning you have to take the float pins out and remove the floats. Place the floats in a cub of gasoline and make sure that they actually float.

Remove the float needle seats and clean the screens that are on it.

Remove your main jet and pilot jet, make sure they are good and clean, look through them and make sure you can see light and that theres no debris inside them.

Take compressed air and blow out every single little hole in the carb. never know what kinda creepy crawlies or debris could have gotten up there.

as far as the screws go, go pick up yourself a nice allen key head set of carb screws (these come included if you purchase a jet kit from Factory Pro).

After re-assembly, set your idle mixture screws to 2 and 3/4 turns out.

and go from there.

You should also have a sync done, this can be done by eye with the carbs removed, however will still be off a very slight amount but will do until a proper sync is done.

 

yes sir i did that we have a shop at my work they would idle before i clean them with choke on but since i clean them as to book it won't idle even with choke on and there is fuel in bowls but there is nothing coming out jets not out even one carb will pump it jumps and wants to start but won't and seeing the screws all tour up on carb thinking carbs been an issue

 

hmmm, i would check and see if you have the boots on there securely, as the vaccum from the engine should be pulling fuel out from the pilot. Unless you have an improperly adjusted pilot. I assume you tried turning the idle screw up a bit to allow more air in when starting? Reason i ask if the throttle plates are completely closed then its not going to start.

 

got it runnig idles,s good choke works as should no smoke but no power wants to go but just bogs has new plugs tank and carbs seem to be as should but it kinda makes sucking bogging sound and won't go
