Carb balancing vacuum take off
Hi, anybody know what size the vaccum port thingys are (for balancing the carbs ).
Mine have been removed and replaced with bolts for some reason and i was gonna get some replacements from carbtune.
Trouble is they're either 5mm or 6mm ??? And im not sure which is correct
Cheers if anybody knows.

Are you talking about the standard screws?
As standard the bike have screws blocking the holes then you swap out the screws for the brass rods to balancing.
