Choosing carb Pinasco 213

Hi All,

I have a ported 213 pinasco with 57 mm cut crank and sito plus exhaust. I would like to upgrade my standard si 24 carb to either a 28mm (J40112000) or 30mm (J40111000) Malossi kit  What would you suggest for my setup the 28mm or 30mm ?

I would obviously need additional main jets, and would like to buy a pack. Which is the correct main jet pack for this carb ?  

thanks in advance

why not try an si26/26 spaco carb, i dont think the 28/30mm carbs will benefit you with 57mm stroke and sito plus
