Differences in BS34MM Carb's, Need advice!

[Guest]

I am looking to buy a set of carb's. My bike is an 82 GS1100EZ, with the original Mikuni Carb's. The carb's I am looking to buy are the original Mikuni's off of an 1983 GS1000. Can anyone tell me if they are the same carb's? Parts interchangeable?

Your expertize is appreciated,

Jetting will certanly be different.

I am not worried about the Jets. My carb's are already tuned to my bike with a Kerker Jet Kit. I can always swap the jets if the carb's are the same.

Thanks,

IIRC, all the bigger bikes of that era used the same BS34s, just the jetting was different.

I picked up a set of "parts carbs" off an 850 on eBay and, except for the jets, they're identical to my '83 1100GL's carbs.

850s normally have 32 mm carbs

I would be correct then in saying "that there is no major differences in the Mikuni BS34MM-SS used in all engines" other then possibly the jetting and maybe some cable linkage?

I want a set for parts and to learn on. I want to make sure that the diaphragm's and all of the other main components would be interchangeable. That way if I need something in the future I would have the parts on hand.

BTW, I have been waiting on a diaphragm for 2 weeks now. I was told by the repair shop they are OEM parts only and have to come from Suzuki.


Your input is much appreciated,

Could have sworn 850s had BS34s. The auction I got my "parts" set from said they were off an 850, but since I found a set of Keihins off an 1150 to use for my 1100 I probably won't have much reason to pull the parts set apart and find out what size jets are in them.

zuzu: would they be BS34s if there were major differences? I think you're putting too much thought in to this.

Thats was my thought, But I wanted to be sure before buying a set for parts.

Thanks
