ok i bought a used set of 34mm pj carbs i put them on and havent got my bike to run right at all one side is always messed up so i look at my carbs and the numbers that are stamped in them are diffrent my friend just ordered some brand new kihien 34mm carbs and they have the numbers stammped in them are the same on each carb. so do i have 2 different carbs or what i also think that the slides are cut different but they look like they are cut to match the carbs cuz where the slide rest on is taller than the other.
