main jet and holder

does anyone know where i can buy a 4 105 main jet and holder for my kz 650.Found some on ebay but they sold quick

Try Z1 enterprises Pick you year then go to carb and pick them out
www.z1enterprises.com/catalog.aspx?pid=KZ650

i tried to find them there but no luck.They dont look like the regular main jet they look like a main jet with a tube attached to it with holes in it.do you know if i can change them for the regular slyle jet?

Which bike/carbs are these for? Pics?

It would help to know the year and model of the 650. But if I am correct the part you are calling a main jet with a tube attached is actually 2 different parts. The main jet (the 105 you are looking for) screws into what is called a bleed pipe, which screws into the carb body just below the needle jet, which is pressed into the carb body.

I have attached a parts diagram from a B1/B2 which shows the parts of the vm24ss carbs used on those years/models. Depending upon your bikes year and model the part#s may be different, but the parts are very much the same.

The main jet is # 28 and the bleed pipe is #26 and the needle jet is #25.
