Carb identification help

[vern]

Hi, can anyone help identify which carbs these are on my 91 1100? I had them refurbed and I think the guy had put the wrong needle jets in as they seem to be too long.

There should, if it's not came off a number one the body of the carbs. 

Do you know if they are 36mm or 38mm ?

Hard to say from that side. They look stock, but without seeing the other side and if there's a power jet circuit or not, and without knowing the size, all of the BST carbs from back then look pretty similar.

Hi,

Ok, the internal diameter where it goes to the inlet manifold is 40mm, which I'm assuming means it is a bst40? But, the book says the needle jet is a p2 which is what is fitted, but it moves by 3mm! Pics attached.

Show us a photo of the left-hand side. There should be a part no.

It is really faded, I can see 410 but not sure what else is there.

There you go! Clear, isn't it!? That was an unusually faded part no.

The carbs look to me like they are bst 36

if they are 40mm inlets then they are the right carbs for a 91 1100m model

id be more worried about those filters, they never work right, do you still have the airbox?

if so id fit it.

Also the emulsion tube looks like its moving, which isnt good. id be taking them off for a strip down and check, persona;lly

Thanks, yes the emulsion tubes do move and I'm not sure why. It's like they are too long. I sent them for a clean and overhaul but the guy says he didn't change them, so I'm a bit stumped. I don't have an Airbox  yet, but am looking for one.
