Oil pump and more capacity

i have one question
I want change cylinder, piston etc - PX 125 on the kit DR 177
and change carb: SI 20/20 with oil pump, on the SI 24/24 with oil pump.

What i must change in the oil pump,
I think must be more oil because its more capacity but i don’t sure what change.

I don’t remember for definate but I don’t think there’s a differance in the ratio between the pump’s.

I think it’s the same part.(Correct me if I’m wrong anyone).

You’ll be fine then,don’t worry.[;)]

I looked in the catalog of parts and oli pump to Px 80-200 it’s the same but only different to engine T5.
But i don’t sure [:(]
