jet size

plz help im trying to find the stock jet sizes for a 1978 kz650b, so i can build from there

In 78 there was a kz650 B2 and a B2A which one do you have - there are differences between them. The B2 came stock with vm24ss carbs and the B2A came with vm22ss carbs. I have created a couple of tables that have what I think are the stock carbs and their parts.

WOW That is useful ..i wish i could find a thing like that for mine

Thanks much, and your bike is killer bro. Im going out to garage to get some info from my carbs, and measure some things, i finished rebuilding the engine and finally heard it run. it was a basket case when we bought it on craigslist and never heard it run so it was cool to hear it run albieit not well but it did start. i needed base line to figure jets after mods, wiseco 710 kit, gpz 750 intake cam kz exhaust cam dyna elecs and header. thanks for info it will really help.
