Identify these carbs please

Here is a picture of a carb bank that the sell thinks are off of a 650 Maxim. Are they? I thought the 650 and 750 where the same, these are obviously off a bike with two petcocks.

 

Those are not 650 maxim carbs. Mine have the adjustment knob at the bottom. As to what they are from I cant help sorry.

 

I know they are Hitachi just could be they are not off a 650 or could be non Yamaha all together.

 

XS1100. They have got the vacuum advance spigot coming off carb number 2. Plus they've got the so called "octopus" attatched to the vacuum to the carb intake rubber. Mikuni BS34's.

 

I was going to say that they're Mikunis, not Hitachis.

 

Ground-Hugger, They are Mikunis, the little tube which goes from the diaphram chamber to the bottom section is a design feature found on mikunis, not Hitachis, also the carb hats are cast aluminum, Hitachis are stamped steel. They probably came off a Kawasaki or Suzuki.

 

OK Fitz you have more knowledge on this then me that's for sure, so I'll go with ever you say. Now are they from a XJ650? Or something else thats the real question.

 

They most certainly did not come from an XJ 650.

 

Yamaha XS1100 SF or Special.
Would you like me to go and photogragh both sets that i've got on my bikes?

 

If you don't mind FJ111200 I'd like to see a comparison.

 

OK, but it's 20.36 here at the mo', and i'm half pissed and it's cold outside inmy shed, so can you wait until tomorrow? :lol:
But i swear to you my old, they are deffo Mikuni BS34's from an XS1100 SF or Special. The XJ1100 had the same carbs but the MK 3's like an FJ.
But i promise i'll take a picture for you tomorrow. :wink:

 

I'm in no hurry FJ111200 you do it when have time and its not so cold.

 

They sure do look like the carbs on the XS1100SF I have in the shop.

Why do you want pics? The carbs are coming back off probably Monday so I could shoot some for you.

Who is selling, and how much $$ wanted?

 

Well I was looking at buying them but he has no clue what they are for and I new they could not be from a XJ/Seca 650.

 

BS34 Mikunis from a 78 or 79 XS1100, standard or special. Could be either one. 78 and 79 were the only years with the cast carb hat, 80 to 82 1100s have the chrome stamped steel hat.

 

Here you are then G-H.
I forgot that i'd taken this set apart, but look at carb number 2, you can see the spigot for the vaccuum advance to the right of the centre of the body, you can see the plastic cap covering the pilot screw, and then in the second picture you can see the knurled idle adjuster nut and the two fuel inlets. These havn't got the "octopus" but they are exactly the same.
Mikuni BS34's.

 

OK thanks a lot I really appreciate the trouble you have gone through. I'll be purchasing the carbs. Just needed to know for sure what bike they fit. I knew they were not for an XJ650.

 

Just a bit of an update on those carbs. I bought them for $19 dollars off of Fleabay. Had a bit of a discussion over shipping. It started out at $39 and ended up at $50. I refused to pay that as he had quoted me $39 from PA to Ontario. So I made it clear that I would no pay $50 shipping since he quoted me $39 BEFORE I committed to buy it. He saw it my way and I paid the original price quoted.
