No idea. Are the part numbers the same? Check partzilla for the part numbers of each respective bike. You might need the carb boots as well

Please do not post the same or very similarly worded question in multiple subforums.

Sorry that you have not received more help for your unique model.

Change inlet manifold to 38 and a kx carb will work.. kx 250/ 500 inlet manifold are 38 ... your con rod small end is a different size to a kx . One is 18 mm bearing and the other is a 19 mm bearing... also kx wrist pin is in a different place to kdx piston.. you can fit a kx con rod and a earlier kx barrel 89 /90 . 70 mm stroke/ 91 92 use 72 mm stoke so won't work unless you machine top of barrel. I had my head machined to lower squish gap .
