Carb size suggestions

[Fabrizi Dude]

hey, i am building an 80cc Gilera Runner motor but need help selecting a good carb for it.

Out of PWK 28, 32, or 34 which do you feel would be more suitable for the engine.?
Also for the bigger sizes what manifold would work with them ?

for the manifold, you can choose the 2fast manifold

i would go for the mhr or 2f4r inlet with a 34mm koso carb..
I wouldn't go for the 28mm keihin because the inlet speed of your mixture is going to be to low with this intakes

only worth's it if you use a 28mm carb

our fabrizi kit has a 26mm carb and runs well, but we drive on the street.. for drag i think its better to use the 28 or bigger..

30-34mm manifolds

just to let guys kno if you are looking for a bigger size manifold ( 30mm -34mm), i would recomend checking out JS-Tunings manifolds. i just bought and recieved my new JS manifold and i am very pleased with it. it needs a bit work to work with my 34 carb because its for a 32mm but other than that i am very pleased. good job Joel
