Rubber manifold K3 & 069A

(1/1)

Hi everyone,

I tried to look for this answer everywhere but it seems I can find a straight answer, I have a 550 k3 with 069A carbs. The rubbers for the manifold are the K3’s one which means the carbs don’t seat against the rubber (I have a gap of a few mm).

Now that could create  some vacuum issues. The carbs has 2 grooves and my rubbers only 1.

If I buy a manifold rubber for a F1 would that work?

I’ve seen that the intake manifold got 2 grooves while mine has only one so I’m not sure if that would work.

Bryanj:
Fit 500 or early 550K/550F manifolds and rubbers, that should all fit properly, manifold O rings to head are same as tappet cap ones

Trigger:
To fit 069A carbs to a K3, you will need the 500/550F type manifolds and the rubbers  ;)

Brilliant! Thanks everyone!
