i have owned nothing but mikuni carbed machines, and this one is way different i have no clue on how to adjust it.

i need information on how to adjust my Keihin carb on my 78 yamaha exciter 440. i just picked it up the other day and it is a real piece of work. i have cleaned the carb kinda, It starts just fine if i have it on choke, it starts off slow then it rev's high. when i turn the choke off the motor acts like it is fuel deprived and it dies down and kills over. mine has two regular fuel line holes on the clutch side and two small fuel holes in the top of the carb. i was told that the two small were overflow's and the big hole on the top is a overflow also. is that correct?

how do i adjust the keihin carb?

well your carb is gloged up my 1980 excter did the same thing blow out all the ports in the carb with compresed air and put a new fuel filter in it and it should respond better and run with out the choke on
