Are there differences between the 750and 800 carbs? I have cleaned both but didnt notice a difference.
 

overall size is same, but different jetting like posted. on a side note: people have asked me about the stock vmax 800 twins on the 750. they will add hp, but you must change your 750 jetting to 800 spec. 3:16 (yammie tony)

They both will have the same pilot jets.The mains will be @135 in a 750 and @143.8 in the 800.Both 750 and 800 use the same needle jet(or nozzle to some people)which is a type 499 Q-4.The needle in a 750 is a 6GN14 and the 800 uses a 6GN20.To tell the difference right away by eye,is that the 800 carbs will use philips screws holding the main body of the carbs together and the 750 uses tamper proof torx screws (these screws dont ever need to be removed!) Hope this helps you out?
