I'm using a throttle body from a European '08 Kawasaki Ninja EX250, which was the first year of factory fuel injection for the Ninja EX250, in my '05 EX250 fuel injection project. My tests on the injectors that Kawasaki used in the throttlebody of the '08 model indicated that the injector flow rate is right about 215 cc/min.

but isn't that one using double throttle bodies?

or the the injector still using part number 49033 0031?

I bought the throttlebody out of a bike breaker in England. An '08 that was crashed into a pond shortly after it was purchased (apparently this was one of the first fuel injected EX250s sold in the country). The throttlebody is a pair of separate 28mm bores with fuel injector for each cylinder which, as already mentioned, flow tested out at about 215 cc/min.

I am not sure but the new Kawasaki Ninja 250 comes with a 38 mm throttle body. The Old Ninja 250R throttle body must be smaller than the newer version.
