hey guys,

a newbie here but been watching your forums until such time i can consider myself a bandido and finally just registered. i've got my first ever big bike a week or two and its a GJ74A model bandit 250.

my problem is, there's an overflow on the #4 carb when in idle and i have a little knowledge about bigbikes.

is this also the reason why my bike is hard starting? can anyone help me especially the gurus of the bandits. TIA

I had the same problem on a motocrosser I had. After many times ttaking the carb out and cleaning it I never really worked it out. Then a mate pointed out that the float was jammed down which meant that it was constantly flooding the carb and I was wasting fuel through the overflow

Might be something worth looking into on your bike. let me know how you go!

check that the float valve needle is seating properly and that the float height is ok.
gunk in your float bowl can stop it from cutting off the fuel supply resulting in it overflowing.
try this link for a little info on cleaning the floats and float bowls.

sir echo, thanks for the link. after cleaning the carb and fixing the float valve, do I need to synchronize the carb again? thanks!

@sir jonno - i'll post the development when done sir.

Can't hurt anything by checking...

got my bandit carb done. am satisfied with it. the number 4 carb's float valve holder was damaged and we just put an epoxy on it and walaah, solve the overflow.

is it ok to remove the spring holding the float valve?
