fuel not getting through?

[tobomoto]

hey all just needed a bit of help on my bike. i just tried starting my zxr and it was leaking fuel whenever i pressed the starter button. i took the tank off in case any fuel lines were loose but they seemed fine. there did seem to be some fuel around the carb breathers though. i was wondering if its just a case of the carbs need cleaning? it gave a MAHOOSIVE backfire almost as loud as a gunshot if thats any help. cheers all.

if you have fuel leaking out of the overflows then its not a "fuel getting through" problem, you are flooding your carbs. you will need to remove them and reset the float heights, they should be 11mm, i suspect yours will be bigger, 13+mm.

either that, or you have a problem with the fuel float needles that one or more are damaged and are not sealing properly. either way, you gotta remove the carbs.

Bugger. Not what i wanted to hear really. I thought they might be gunked up as they havent been used in a few years. Another job for the bike shop to do then i guess. Cheers for the help.

Its not difficult to clean and set up your carbs, I took all the pictures for a guide but need to make a photobucket account
