KZ400 carb inlet leak

[2_DONE_THE_TON]

Hey guys!

Just figured that my KZ 400 has a gas leak between the two float bowls (inlet where gas enters the two float bowls).How can I change the seal, is there even a seal in there? looks like there are O Rings in there..32 in the pic below.
Looks like my right float bowl constantly gets less fuel than my left one due to this leak.

Hope you guys can help me out!
will post pics later!

Simple o-rings. Probably has no affect on the carb - it may leak, but the fuel level in the bowl is still regulated by the float system. it would have to absolutely pour out fuel to not be able to keep up with the fuel needed by that cylinder.

^this.

I´m currently running a full trouble shooting on my KZ, it has starting issues,it starts bad.
It only comes to life when I pull full choke and keep on gassing it.

Ignition timing and valves just have been checked.
Carbs cleaned and float height set.

Pulling the plugs it looks like one cylinder is running leaner than the other one,thought fuel starvation could be the issue.

One cylinder heats up faster,fresh new plugs and plugs that go onto the spark plugs.
Oh and membranes of the carbs are spotless

Stock carbs with K+N filters (I know that these will be hard to run on these carbs).
No air leaks (checked with brake cleaner around the carb boots).

Hope you can help!

You'd have to split the carbs, pull out the t-piece and fit some new o-rings. But as Mobius said: It's merely a nuisance rather than a real issue.

Fix it right or it will forever tick in your brain... Simple o-rings and while apart you can give them a thorough cleaning... Carb cleaning is like therapy so enjoy it.
