Kawasaki KZ650 cafe-racer. Carburetors: exploded view.

Carburetors have come a long way of “evolution” since they were invented and in time they became quite complicated. It’s quite a lot of work to adjust carburetor to work perfectly in all range of engine RPMs, so no wonder that average carburetor consists of many parts. But of how many parts? That’s depend on type of carburetor,  its manufacture and production period.

However, these “exploded view” photos may give you an answer for this question in case of Mikuni VM24 carburetors with accelerator pump from Kawasaki KZ650 motorcycle. I couldn’t decide which of two photos I shot form slightly different angles is better so I decided to post both.

    one question, in repair kit you get 2 different air screws. one a bit longer (2mm). You can see on the picture http://jeffwerner.ca/wp-content/uploads/2017/11/IMG_20171107_103407-1-768×576.jpg . I am rebuilding mine carbs (kz650b2 1978) without pump. Previously there was a longer air screw, so I’m about to use the same, but I can see some use the shorter one. There is almost no info about this on kz forums. Would love to hear your oppinion.

    cheers, Tomo

      Hi Tomo,

      Sorry for the late reply.

      I think both of them will work. However, I’d stick to original configuration of air screws. I have a set of KZ650 carburettors without pump, and they are equipped with air screws similar to those on the left side in your picture (shorter ones). Also I have to admit that repair kits I used to restore carburettors have only a longer type of screw.

      Kind regards,
