I want to get more air and more power does anyone know where i can get more mods.

 

Theres usually a tradeoff with carb size. Just adding a bigger diameter carb to a stock motor, will usually result in lost low end torque. The smaller diameter carb produces a higher velocity than a bigger carb, ...more velocity=more torque. But if you do alot of head work, and change cams, there could be a small gain, remember its only 250 cc youre working with, there isnt going to be any big gains.

 

ok thank for the insight didnt know that.
