bst34ss carbs

[Guest]

Recently found a guy selling his carbs off of his '88 GSX1100F for cheap, which to my understanding are the bst34ss carbs. I know the 36's are common swaps on gs1100's, but what about these?

They will fit but you will need a DJ kit, pods and some adjustments of the float to work on GS models.
I would look them over before buying them. The slides hammer the slide guides and wallow out the emulsion tubes and ruins the jet needle. Even with a DJ kit which includes new emulsion tubes if the guides are hammered it won't be long until you ruin the new parts.

I figured I'd need different jets. Should I treat the jetting configuration like the stock gs1100 carbs with pods? I'll also examine the guides.

Use the DJ kit for the BST carbs.
Use the smaller main jet for the stage three and set the needle as suggested.
Set the float as far as you can or with the angled bowls or you will just leak gas into the engine.
