Using GS1000G carbs on a GS1100G engine

[JTGS850GL]

I think that I have the differences between them as follows:

Jet Type	GS1000G	GS1100G
Main	115	115
Pilot	40	40
Pilot Air	200	170
Jet Needle	X-6	X-3
Needle Jet	5D50	5D58

How critical is it to swap out these components. I have the pilot air jets so that's not an issue but I would have to buy/swap/trade the Needles and Needle Jets.

Just doing some information hunting for my next project. An 1100G engine rebuild and swap into my 1980 GS1000.

Bump.... Anyone?

i think that the 1000's still use bs32 carbs where the 1100's use bs34 carbs. i could be wrong. you would need to download a gs1000 manual and look at the specs page to see what carbs it uses. i know the gs1100's use bs34 carbs

Chain drive GS1000s use 34mm carbs. Pretty sure that the shafties use them too.

Yep, all 1980 and later 1000's used BS34 carbs. Still trying to see what changes would need to be done to the carbs in order to make them workable on an 1100?

The bodies are the same, so I'd think changing jets and needles would be all you need. I know that wasn't anything like authoritative, but at least you get a bump out of it.
