i don't know how to put image but how can i know if a polini cylinder i have is corsa?

you can't tell from the cylinder bore. from the outside they all look the same. from what i remember, if the head is black=corsa, if the head is silver=contessa.

exh port will be factory hand ported on corsa

i don't have the head because it is second hand.. I can know if is hand ported or factory portef.. What is the differences?

Never buy a bore kit second hand, if you can't afford speed then stay away from it

i rehone it now maddog and it is new polini 48mm kit..

polini kits are 47mm, whats this 48?

I have a scratched used polini bore (which I sneakingly think is a contessa) and was wondering if I could overbore (I'm not sure honing will take out the scratch) to 48mm. I wasn't able to find a 48mm piston so I kinda gave up on it.

get plenty 48mm pistons. for what kind engine dio or af05?

I would think being from Hawaii, I'd say the probability is >95% that its for a DIO. We throw away AF05s.
