Cylinder udgrade help

Hi, im on my first restoration and need some advice pleeease. Firstly what do i need to upgrade to 12v and add an ignition system? mine is a four wire kind.

Secondly ive got a little damage on the cylinder and thought about getting a kit to improve performance and reliabilty, if i get one of the 177cc kits do i need to get the original cylinder rebored/skimmed?

any help will be very appreciated
