Seats were machined in CNC shops, after around 10 trials everything is still leaking.

I have sent an email to the Keihin corporation. I am curious what could they do.

In my case they sit well.

I tried it. It reduced the leakage. Situation was 50% better. But couldn't fix the problem. So I am sure the pressed seats are the reason! No idea what to do, while the seats are not replaceable.

Why not, but maybe better to use CNC mill with precision tip?

Changed the the float valves twice. Genuine kit and tourmax kit, in both cases still leakage is present. Float is at the good level. So only the seats can be worn.

I checked that the bandit 600 carbs can fit inazuma, however there are no such carbs in the good condition in the market. I could buy a crap for 150 euro here The problem in my case is worn needle valve seat. While it is not replaceable, I don't know how to fix it

I had to remove the engine from a frame and then the airbox.

I installed the carbs with K&N filters instead of the airbox. Maybe it was a reason that tuning was so difficult. Rubbers between the head and carbs were from 750 inazuma. Experimented with jets, but couldn't achieve success. Flat spot appeared on mid and higher revs (like main jet and needle)

In bandits and teapot, they are pressed in and replaceable. In inazumas not.

Oh no. The seat is in the place where tip of #22 sits. You can't see this in the picture.

If you are right, that would be a good solution, while in bandit 600 valve seats are replaceable

#26 is a needle jet. Has nothing to my case of the fuel leak

This is what I supposed

Yes. Stock frame and engine
