GS1100 EX carb swap?

[will61310]

Which carbs will fit my 81 gs 1100E? I know gs 1150 , but theyre hard to come by, not sure if any bandits will fit. What year gsxr carbs work? I dont want to change my throttle control to a push pull, but want to go to a 36 mm carb.. ...Thanks, Will

Do a search for Slingshot carburetors.

Stock 36mm CV Flatslides are generally considered good street carbs, but the RS flatslides offer more power but cost more money.

The 36mm Slingshot carbs came on both GSXR 750's and GSXR 1100's generally between 88-91 You identify them by the oval input ports.


There were a set of Bandit 36's for sale (GSR parts for sale) $100 delivered just last week.

Bandit 36mm CV, from the first gen 97-2000 will mke the 1100 run like a beast. Katana's had the 36mm crabs also. Put a stage 3 jet kit and some filters in it and it will run like a champ. GSXR11000's had the carbs too. 750's had 38's Bandit 12 carbs are eaiser to find.

What Stage 3 kit would be required? I have purchased a set of these a few weeks ago and then searched on the Factory Pro web site for Stage 3 jet kits. I believe that they offer more than 1 Stage 3 kits. Are these all the same, or should one order the one intended for the Bandit 12, for the GSXR1100s, or for a GS1100 motor?
Thanks!

Actually I got my jet kit from dale Walkers site. he sales it. it is the stage 2 for the B-12 carbs. you can buy the kit with or without the K&N filters. His kits work really well and I just bolted them on my stock 81 GS1100E and it made a heck of a difference. I used some pod filters on mine.

So would that jet kit be a good option for slingshot BST36 carbs as well?

Nope
even though the carbs are very similar there are subtle differances, eg with some kits you MAY need to drill the slide lift holes & with others you wont, imo you would be better off with a kit intended for the slingy carbs

As with all swaps like this the jet kit should only be viewed as a starting point so dont expect it all to work great straight out of the box, you may need to order extra jets to get it fine tuned

Port spacing on gs-gsx etc engines is the same as all the oil cooled gsxF gsxr & bandit engines so that opens up your carb options a great deal, but be aware the intake rubbers differ slightly

Slingshot & bandit 12 carbs are semi flatside btw

Dale did a lot of work for the Bandits. all the carbs do differ. If I remember right I had to use the 155 mains that came with the kit. needle in the 3rd clip position and the small pilot jets. It ran flawless here in Alabama.

I try to refer to the Slingshot carbs as CV flat slide; sorry if I slipped up .

I do a have a couple of Dyno jet kits for the Slingshots. One is GSXR750 and the other GSXR1100. Bill and I will likely be having a Slingshot carb weekend soon. One set on my GSXR1100G, one set on my GS1100ED and one set on Bill's GS1100L/ED :-\\\

I have heard several negative reports from GSXR guys about DJ and these carbs. The issue is mainly the needles and erratic operation. Factory Pro are generally preferred but I already have money in these DJ kits.

Big T nice to hear it worked out so well. Not that I really need any more power , but what the hey .

Did the carbs effect your gas mileage any other than what would be expected from a heavy wrist?

Not that I could tell. throttle response picked up greatly and you could notice the power by your seat of the pants dyno. .

The name slingshot was originally the name suzuki gave to that design of carb but has become the common name for the bikes themselves
If you say flatslide carbs a lot of people will straight away think proper flatsides rather than the slingshot etc semi flatsides this can cause much confusion & wasted time when trying to help someone set up their bike over the net untill the mistake is realised

Sorry if that sounds picky mate but i hope you understand he reasoning

Anyway onwards & upwards ..... DJ kits will work well in these carbs but are harder to set up correctly than some other kits, this is down to needle design i believe, a lot of the negative things you see across the net on jet kits of any make is down to inexperiance & impatience of the people trying to install them its certainly not a fit & go job especially when you are fitting carbs that were never meant for that bike
More problems are caused by people not knowing that the emulsion tubes on these carbs wear badly with stock jets & even worse with an aftermarket kit, i replace these as a matter of course & have found fine tuning much much easier
People also mess with float heights & change the pilot jets simply not required on a stock engine & causes even more trouble
One clip on the needle relates to around half a point on the jet (DJ) so if you are all the way up or down on the clip you are running the wrong size main jet & will struggle to fine tune it, the idea is to aim for one of the middle clip settings to leave a little movement for fine tuning

hope it all helps
