KZ200/Kz250 ltd carb

Looking for information on the kz250/200
i recntly purchased a 1980 kz250 ltd that has a kz 200 motor in it. is that common ?
the carb was shot so i ordered an aftermarket one. ( mikuni vm26 ) 110 mains 17.5 pilot) from what i found thats most compatable.

anyone have any info on this ?
am i close ?

I don't know how common that swap is but I just put an '80 LTD 250 engine into my KZ200 because the motor was shot. I'm using the original KZ200 carb with my swap and had to mod the carb insulator to fit the different screw pattern on the head. My smaller carb seems to work fine for the moment with the bigger engine. I have the original Keihin carb with 105 main jet and 38 pilot jet (slow jet).
