What bike are these carbs off of?

No eBay APP ID and/or Cert ID defined in Kunena configurationMikuni BS32's. I thought they were GPz750 carbs but they only measure 32mm.

Suzuki used the Mikuni BS series CV's for many of the GS models. The biggest bores were the 36 mm GS1150's.

Yamaha used them also - the old XS650 Special vertical twin used them (I have three of those engines in my barn waiting to be built into 60's retro bikes someday - a 60's metal flake and chrome hard tail chopper - just for the hell of it, a scrambler off - road bike, and a Triumph Bonneville looking / sounding roadster)

I forgot to add, the Yamaha 650 version is about as close to the KZ1000 as I've seen, most parts are the same. And those 650's will shake your teeth out at idle.....ahhh, the good old days (stone age?).

[strike]This set is not from a Suzuki GS. [/strike]They look like Kawasaki carbs in terms of the plastic tops and the gang bars are identical to those on the GPz750. Did any KZ bikes come with 32mm Mikuni CV carbs? These carbs have a cable actuated choke too. Guess I better start looking at the parts fishe...

EDIT: changed my mind. I now think these came from a California model '85 GS700 Suzuki. The model that came with the charcoal canister, thus all the extra plumbing.

I was about to say, I have a picture of a '83 GS750E that has those carbs on it in an issue of Cycle Canada, specs say Carburetor: 32 mm CV.

Zepher 750?

These may be off a 1982 Kawasaki 750 GPZ R1. The R1 model has the Mikuni 32 CV carbs.

Sorry for not updating this thread but the carbs were indeed from a 3rd generation GS750/700, the California emissions version bike from 1985.

Here are a couple of "after" photos...

The 750 R1 has BS34's, not 32's....

Exactly. If it's for a KZ750, it's going to be 34mm ports, not 32mm... Doesn't matter if it's the R1 or an H3 like I've got. Like my H3 left the factory with (and has some reaaaaaaaally nice remanufactured) Keihin CV34 carbs. A couple years later (H5 I think) they switched the H series over to Mikuni BS34. Still, 34 34 34, always 34. I'm not sure about the '70s models though, only the 1980s. Heck, I think the KZ1000s even used 34mm ports because I've think seen a few of them with Mikuni BS34 carbs installed.
