I'm not sure what you're referencing.

I'm not at home right now so I can't look at my EX250 Service Manual to figure out what you're saying about the engine oil pump.

The clutch basket assembly has one big gear on its backside which meshes with a gear on the crankshaft. Kawasaki hasn't changed the tooth-count on either of these gears throughout the entire EX250 history (pre-gen, new-gen, and 300s) so the clutch basket assemblies from each generation can be retrofitted as has been demonstrated by owners (I understand that retrofitting a 300 slipper-type clutch requires also using the 300 clutch cover to provide enough clearance space for the slightly larger assembly).
