Not one for the purists but I have a 78 550 with a 650 motor in, I’ve just put some 069A bottle top 750 carbs on in place of the stock PD51A’s as I plan to run it with pod filters and a 4/1 and they are much easier to tweet. My question is is there a cable that will fit ie a 550 before I cut the 650 one (as it’s way to long) and go down the adjustable nipple route.
