GSX1100 carbs on GS1000

[wraith]

Has anybody put the gsx1100 36mm carbs on a gs1000? ( I would think someone out there has )

Will they fit with the standard gs1000 CV carb rubbers or do you need other type of rubbers?

Anything else I need to know with this mod?

Cheers.

Thought the std 1100 carbs were only 34mm ?? Maybe the later EF were 36??

Yes - they were. I've had 2 EFEs both with 36s.

I put the 34mm ones on my GS1000, who had the 26mm carbies, milled off the head and put aluminium plates on it and milled that from 26 to 34 mm with a tapered mill, runs beautiful, way better then the stock carbies, but something tells me you're not after this kind of info...

 

Put some petroleum jelly on the carbies or heat the manifolds up with a hairdryer, then they should go into the manifolds.

If what you want to know is, do 34mm's go better then 36mm's, then yes, but you only notice that in the higher revs, or highway use

1075cc gsx motors inc the katana have 34mm cvs, 1135cc (efe) had 36mm, kat 1000 had 32mm slide carbs,  i know the efe ones fit the kat engine, so im assuming they fit the gs engine too with a bit of fettling.

i have put an entire gs 1100 gl topend on a '78 gs 1000 lower end with 34mm gsx 1100 carbs. runs great on it. i think you will need other intake rubbers if you want it to fit on a standard gs 1000 head wich has 28mm carbs. maybe you can find a gs1000g head somewhere?

Cheers all for the replies,

I asked because I sore some on the bay, for not much money.

I have gsxr 1100j carbs on the GS at the moment.

Just for info you can use z1000j carb rubbers on the slide carb heads to get a CV carb on them  

Here's a pic of my gs1000g a bit modified

carbs ... the bigger you go, the more time you'll spend in the region of the carb you don't want to be - where the mixture is influenced by multiple jets and jet needle.
 

I talked to someone that built a 1187cc GS1000 engine with approx (rear wheel) 130 bhp together with his buddy Roger Upperton.
He told me for road use, don't go too large.

Smaller carbs will be in the throttle region sooner where the mixture is only determined by the main jet, and run nicer.
CV carbs are more forgiving in this regard than large slide carbs and flatslides but tend to respond a bit slower.

It's just the top speed that will need all the fuel you can feed the engine so if you spend most of your time full-throttle on the Autobahn, go big.
He ended up using 33mm TM carbs but was not after max. power but wanted a bike that was good on the road.

Pic is of his bike, i wish ..

Looks like an expensive Racefit item

Not expensive considering the quality, and they fit nicely and sound better.

[Simbec1863]

Agree they are quality but affordability depends on how deep your pockets are
