Piaggio zip 125 head

Hi all recently got a zip 125 engine for my ice as you'll all know it a 2 value can I fit a 4v head if so what would fit or would it be easier to fit bigger cam?
Any help appreciated
THANKS

 

A 4v head won't work as there water cooled, fit a 190cc barrel !

 

You state won't work as water cooled that fine don't want to get a kit as to many things have to do to go with kit do you have any other suggestions for acceleration not going for top end speed
THANKS

 

It's only a 190cc barrel/piston kit that's it, nothing else. Simple!

 

So dont have to jet carb or do rollers and clutch for kit as I did when done 70s for my 2stroke . 4stroke new to me

 

Yes a bigger main jet but you can use all the std transmission.
