Which Carbs do I need?
McCabe-Thiele (Ted):
Looks like the part numbers for K1 & K2 are the same so you will be looking for a set of 069A carbs with the correct manifold.
I consider myself a novice so you need to get confirmation from Bryan or others - I guess you should be able to tap holes in your existing manifold for the Vac points.

Hi Nurse Julie
the bike came in bits so I haven't taken any photos yet, but if you let know which parts would help I will happy up load some.
As far as I am aware its a UK bike, but I am basing that of the HPI report which has it down as first being registered in the UK on the 4th August 1977, still waiting for the V5 to come.

Ted its not as simple as tapping a thread as the k3 manifolds are a different length.

Ah so it needs a mainifold plus a set of carbs on the correct bracket - then the air box as well presumably.
Is a K3 the same frame dimensions for fitting it all?
These look like the manifolds as they have vacuum screws or is the 550 different spacing to the 550?

That's not a bad price for the 500/550 manifolds with the balancing ports.
Get 069A carbs if you can. Or if not 627b or 022A (but these may need jet changes)
As said F2 engine is the same as a K3.
