I just got this bike and am looking to swap out the carbs. Looking for suggestions as to what i should look into. anything helps. Thanks guys!!!

right now it has KOSO 34's on it with different size jets from the last guy lol needless to say it wont idle. instead of replacing the jets id like to get new ones. since these are really beat up

KOSO? post some pics. I would go with 80-82 sohc xs400 mikuni bs34 carbs. Lots of replacement parts made for them as the xs650 used the same bodies from 80-84.
