75cc kit on a v5a

Hi,

I have a v5a which is not very powerfull and has trouble accelerating,

I wish to change that by putting a 75cc racing kit, I know that I have to upgrade some other parts,

carburator, bearings (that have never been changed I think),...

What stuff do I need to buy for that??

 

thanks in advance

excuse my technical english!!!

i do it plug & play at my v50. the only thing i changed was un uprade from delorto 16.10 to 16.16 with 74HD. Nothing more, nothing less and the last time i drive her it runs 70-75kmh
