Gsxr carbs

[Fjbj40]

I have a set of BST34SS carbs off a GSXR1100, they were supposed to be off a 750, but after I opened them up all the jetting and emulsion tubes were 1100 spec.

That being said, are the BST34SS carbs off the 1100 the same as the BST34SS off a 750 except the jetting,emulsion tubes and needles?

Thanks,
Daryl

Do they have metal tops or plastic?

[Fjbj40]

They have metal tops over the diaphragm. They, as far as I can tell, are from a 86 model.

Why?

Thanks

I have a set off of a 1100 gsxr, '86, that are BST36. Plastic top. I've had them on my bike about 12 years

hey rich,
those would be 89 and later as the 86-88 GSXR1100 and 88-93 katana 1100 had 34mm vacuum flat slides.
not sure on Canadian spec carbs though.

The metal top Gsxr carbs are 34mm flat slide vacuum carbs the later plastic top ones are 36mm as mentioned some Canadian models had 38mm harder to find.

That would explain why the throttle I bought for an '86 GSXR wouldn't fit

They are USA market carbs.
