I have a question for you guys that someone asked me but I am not sure what the answer is truly. Does switching carbs (bore size I guess) from something like a 500 or 600 to a 750 hurt fuel milage? I told him that I think it does because for me it seemed like when I switched from a 750 to a 600 it got better milage... Could have been that it was tuned wrong, etc but who knows. So if they are both tuned correctly and you swap from a 600 to a 750, will it hurt milage at all?
Thanks!
