Keihin 069A carburettor question

[Murf]

I have 110 main jets and 38 pilot. Does this sound like a good starting point.

I would say it sounds like a starting point, if that’s what you have see how it runs on it, the final set up you are aiming for will make a difference i.e air filter type (standard or pods), exhaust type (standard type or aftermarket), but you have to start somewhere. The Honda booklet about carbs in Ash’s drop box or Aladdins cave has some great info in it.

All I can say is how much patience do you have...at least with pods you don't need spare knuckles!

I had my first ride out on it today just down the street on the PD set of carbs that I gave a quick going through, I didn’t separate them or anything just sprayed the jets through and unseized the floats. The pilot jets were all completely gummed up - finished this late last night and didn’t fill the bowls up until today when presenting the bike to my dad who used to own one in the same colour in the 1980/90s. Once he’d taken it in, I let him have the first kick to see if it would go, and lo and behold it roared into life and ticked over beautiful on the first kick. We both had a go to see what it was like down the street. And magic.

Parts ordered from Nurse Julie for the 069A carbs. I can’t wait to see what it’s like on the other set once gone through properly.

Thanks for your help guys.

As Oddjob pointed out the input manifolds are different for the pd and 069A carbs. Manifolds for the pd carbs do not have a holes (capped with screw) to allow vac synchronization. Also the spacings are slightly different. But I've used 627B carbs (which are basically same as 069s) on a K3 with the pd manifold and the 627b/069a rubber couplings coped and got them aligned OK. The said rubber couplings are different, pd ones shorter.
