STAGE6 RACING CLUTCH
STAGE6 R/T OVERSIZE CVT KIT MK II D=107MM.
STAGE6 R/T CLUTCH BELL 433G.
STAGE6 PRIMARY TRANSMISSION
STAGE6 INTAKE KIT MK2 OVERSIZE with STAGE6 V-FORCE 3 REED Valve

And hpc crank with c4 bearing SKF with polini viton sealings.

I have bought THE MXS RACING CYLINDER KIT 70 CC

all depends what you intend to use the scoot for... if its for road use, The 21mm carb you already have will work fine...

I have used an OKO 24mm PWK style carb on a Stage 6 Racing 70cc as a daily use bike and it rode nice, some people say theres very little difference in power between a 21mm and a 24mm carb anyway.

The Dellorto 25PHBL is also another popular carb on high power 70cc set ups, jets and needles are easily available.

24mm mukini even power jet it, dont buy a cheap koso knock off, but you have all other parts I would maybe go c20 will let if rev more but c16 would work well, depends on what your users are and if you don't mine on off riding in traffic, doesn't bother me I like to have power at the snap of my fingers,
