cam question

[84honda200s]

i have a atc90 engine apart and was wondering if a 125m cam would fit in it ? im slowly but surly modifying the engine. i gave it a port small port job, 22mm carb, and dg exhaust for now. i dont wanna go overboard on it because it belongs to my 12 year old brother. guess who is paying for it all ? anyway any help would be great.

I don't know. Maybe check some parts fiches and see if the cams used different parts numbers?
