BS34 carb variants id

[sockpuppet]

Hello

Can anyone please help with identifying these 2 sets of BS34 carbs ?

The top set are almost like the set of what i know to be J carbs on my b2. -- same 4 airway layout on inlet side .flat bottomed slides and squarish metal carb tops,-
but are finished in black instead of alloy without the round "coaster valve thingy on the side.

The second set have 2 airways and `cutaway` slides , these have round plastic carb tops,

I have a 1100b2 project thats been in the corner for years and i`m trying to decide which set might be best to use when i come to tackle it .

Any help would be greatly appreciated .

Thanks

I think the bottom set are Z1000r2. I have them on mine.

Thanks for that!

I was leaning towards z1000r for those !,

but ive no clue what the top ones are - - i thought maybe z1100 shaft but i think they are silver ,but these are shiny black and it looks a factory finish .

Thanks for your input

1100 Spectre shaft had black Mikuni 34 carbs. Quite a few got imported from the states back in the day.

Looks like they could be the ones ! ,

Now the question i have to ask myself is ---is which set do i use and which do i sell ??
OR
instead or refurbing a set or forty year old carbs , sell both lots and put the money towards some nice shiny new flatslides !?

Thanks
