[fomospede]

this is what we have
70cc MHR cross
pcs pipe
stock intake
pvl
we race xc
we have pwk carbs in 21-26mm in 1mm increments
where would you guys start with this build?

Call Gary at G-force he can tell you what to use .. we have a 90cc with that set up but run 28mm just my 2 cents..

[Hetrick Racing]

Put a 24 on it that will work very well and not rob ur bottom end punch.

[nastynotchback1]

i agree with the 24mm for xc

[#404's Dad]

28mm good quality carb, not a KOSO or other generic and clutch it right, bottom end punch is not an issue with a 28 on the MHR 70 if everything is working in harmony ie: clutching, pipe and porting.
