or an airbox with a smaller inlet hole than the venturi of the carb..not so much to become a restriction, mabey 5-10% smaller.
so ye, theres always a way round a prob to give best performance. build as big as you can afford and you will learn sommin, do what everyone else does an you will just be another scoot with a leo zx the wrong rollers and a filter but ye. big carbs = fun
if you want the big carb to work better make sure all the other settings are right then buy an ignition with an aggressive curve down low to bump it up on the pipe
by changing the igntition will this just improve like acceleration and pull but wont make any more top end will it?
