sorry guys havent been able to get on very much... i have no way to tell what size carbs would fit these better.... my stock carbs were in them when i bought the bike and they tightened down on them they just arent right and i want it to be right thats why i put on here a 28mm or maybe a 30mm would fit a lot better bascically without a clamp a stock carb will just fall out but they did tighten up to a stock carb they are not damaged they are good just pm me your emails of anyone who wants to see them and ill send you a pic
