what size carbs and brand should i run?

[ryansedy]

recently bought a 4mm cub motor ported, be running CPIs or Shearers, I ride mostly all sand and some dragging. Mostly duning hill climbs, what size carbs should i run? over 35mm right? run 110 octane gas.

35's will be just fine for it if you go with too big of carbs you start to loose bottom end if you dont mind that stick some big ones on there for the top end

x2 on that... i would say 35's to 40's would work for that... it all depends on where you want the power to come on with making the choice

i second on the 39's.good carb for hill climbing,dragging with that motor set up.If you got to small you will lag top end,keep that in mind
