im always hearing about how putting a larger carb on a ped will make it faster. My motobecane used to be able to do a constant 25+ on flat ground, which was fine, but now only cruises at 20.i heard that the biggest difference in the faster and slower model motobecanes was just the size of the carb and manifold. Well, i got the bigger manifold, i have enlarged the carb opening and jet, and i even tried my racing carb on it, which has a air/gas mix adjust on it. It seems no matter how much i play with the carb, its just not making it go any faster. So whats the deal? did i miss something? what else could i do?
