Re: carb problem

[rosszx9r]

my zx7r has a carb problem when you switch bike off carb 3 seems to keeps letting petrol through i have stripped carbs and have found that you can blow through both ways in the main jet hole and you can only blow one way on the others have you any idea what would cause this any help would be good

cheers daz

if it's leaking fuel when not running, its the float valve that is not seating correctly. usually stripping down and cleaning is enough but it may be worn. wemoto do replacement kits for around £10

to find it:

take the bottom off the carb, the float has a little flange that presses against a spring laoded plunger (bery small, about 1mm in diameter). remove the hinge pin from the float. this is sometimes held in place with a small screw at one end of the pin. once the float is removed, the float valve can be lifted free and cleaned.

once clean, you will need to reassemeble and set the float to the correct hieght. this can be very model specific so you'll need either a haynes or a helpful kawasaki dealer to give you the clearance figure.

you've done the hard part by taking the carbs out

tryed all that mate but still doing it will order one of them kits i think

just a thought...... there is a small drain screw in the bottom of the carb that has a small hose attached to it.... the drain screw is closed isn't it

some may frown but if you suspect its one of the jets causing the problem why not swap that with on in the other carb?

then you'd know.. - how did you identify that it was letting fuel through after switched off out of interest?

[chrisgatguis]

ah right - you can see the sliders / pistons opening in the carbs?.

when you move the jet to a different carb did the problem follow the jet or stay in the same carb?

what about the little linkages that connect the throttle cable (or maybe choke cable?) up? maybe that one is bust or not moving freely?

lol god knows..

good luck
