Keihin "hidden circuits" designed to offer less access...as a result..simpler...less parts. Perhaps a bit more difficult and resistant to cleaning ...the Mikunis more "friendly" via accees.
Keihin CVK's (on the EX250/500....throttle shafts not serviceable (nor are internal seals and washers) jets thread into carb body (not a removable block) and slide bridges pressed in...aqain not serviceable.
The raw materials used in Mikuni's I think a bit more resistant to condensation. They tend to clean up better (the way they react to sodablast and ultrasonic) and suffer less water "stains"....in the bowls for instance.
Note I'm comparing Keihin sidedraft CVK (on EX 250/500)and Mikuni downdraft CV carbs here used on Ducati twins, Yamaha R6 and YZF1000, and older flatslides used on Suzuki Bandit 600.
To sum up..the Mikuni better materials and design, Keihins simpler....again IMHO.

Thanks Gordon, great feedback. You know, I never liked the idea of a carburetor controlling my throttle input like CV carbs. In fact, I wonder if a CV carb ever gives you full throttle regardless of the butterfly position. How do you know? I'm certain on a non CV Mikuni. Anyway, if I don't ask you to work your magic on my Keihins someday I would consider installing a set of Yamaha RD400 carbs on the Ninja. It would be an interesting project.
Cheers,
Bill
