Helping a buddy out with his 2005 T 100 . Keihin CVK carbs . Experiencing intermittent flooding out of overflow tube . I have had the carbs apart in the float bowl areas . Floats not leaking . The floats are pivoting on the hinges with no apparent issues. Float valves and seat seem to be in good shape . The only path that I can see to the overflow tube is through the float valve . What am I missing? Thanks in advance for any input.

Float valve seats encrusted with residue from storage.

Polish with a tapered wooden dowel (chopstick or kitchen match) laden with Mothers Mag.

Seen it a lot.
 
Check the viton tips on the float needle for damage
I use a Qtip in a cordless drill with metal polish to clean the seat up
I'm not familiar with these carbs but if all else fails the float needle valve seat should be removable
This will have an O ring seal on the outside that may be letting by
