best way to clean carbs on kz400 ltd

best way to clean the carbs on my kz400 ltd please any help would be great, i did the best i could with just carb cleaner.

Carb cleaner and compressed air works just fine. Small compressors work good for this task. I personally disassemble one carb at a time. Soak in Berrymans over night. (Buy it at the auto parts store in a one gallon bucket. Comes with parts basket.) Then finish up with carb cleaner and compressed air. As far as the specifics, do a search. There's all kinds of great articles and diagrams.
