    I have a few pairs, some very crappy. The ones on the bike might be for XS1B.
    How do you spot these are for later years?

    I thought the early (69-71) had a raised floor?

    HI

    I am looking at the diaphragm tightness, and changed one in XS2 carbs. I have 2 sets of carbs with the starter of the left carb feeding also the right carb (the right carb has no starter valve).
    When checking for diaphragm leaks, it seems that there is a leak from the starter circuit. Looking at different carbs, the plunger of the starter has different designs. I even have carbs plungers of smaller diameters that I cannot use.

    With the one on the right, the groove allows some air to pass from the vacuum side of the diaphragm to the starter circuit. It does like a punctured diaphragm.
    With the one on the left, the diaphragm circuit is tight, and I guess a better control of the slide.

    Do you know why this groove should be needed?
    I intend to use the one on the left.

    Any ideas ?
    Thanks,

    Yes the starter circuit affects the diaphragm on CV carbs. It could be that groove that's the problem, but you might look closely at the rubber disk on the end of the plunger, I believe that makes the seal to a ridge in the carb body, if the rubber is hard and or deformed and doesn't seal, the diaphragm drops faster.
