hobbit kits on peugeot 103's: talk to me (2 replies)

i was scoping out the honda/derbi/peugeot metrakits on treats and it struck me that they're all hackably close to fitting.

i've got a stock pa50ii cylinder floating around and i'd like to put it on my broke friend's peugeot 103.

what am i going to run in to? gotta ream out the stud holes? base spacer?
