I don't know the specific markings on the KD100 carb, but mikuni should be right. If it's lean, then give it more fuel. Your carb is most likely a 19mm. Your standard set up should be:

Main jet: 77.5
Pilot jet: 17.5
Jet needle: 4EJ7
Jet needle: O-2 (probably)
Valve throttle cut away: 2.0
Air screw 1 1/4 turn out

And be careful with the aftermarket carb kits. They're only good for gaskets and maybe the float valve. DO NOT throw away the original jets and needle. The aftermarket jets are often not accurate enough (even though they look the same) and can give you more headache than you had before you put them in. If you find a genuine Kawasaki KD/KM rebuild kit you're ok.

Make sure the carb cap rubber is fresh with no leaks and that your float height is correct.

24mm doesn't sound too bad.
My bad.
