kawasaki GPX Ninja 250 leaking carbs

[craisin]

Ive been helping a mate get his bike going. Had to reset one float on the twin carb setup. So it starts with the choke on but wont run without the choke and after it runs for a while it starts leaking gas from the carbs and its hard to see which carb is leaking. I now suspect a ruptured diaphram that operates the slide. Any advice from folks who have had the same problem would help

right Ive figured out by reading some old threads on this site it has a vacumn diaphram on the fuel tap. So I intend to use an old lawnmower tank to set the floatlevels with carbs out of the bikeany clues on correct float level would help

talking to myselfon the side of the crankcase it says 1.3L oil capacity. I drained out over 3 litres.

sorted it with new carb bowl seals. Goes good
