GSXR carbs for GS1100E

[Anonymous]

Hi guys. Has anyone used GSXR carbs on their GS1100's? If so what did you use and how did they work out? I'm looking for some kind of carb with accelerator pumps. :twisted: :twisted:

Come on guys anybody go any Ideas?

I have not tried them but some were putting the GSXR slingshot carb on the 1150`s. They may be to large for a stock 1100. Hopefully someone with more extensive knowledge will help you. With all the new bikes coming out with fuel injection there is a lot of the aftermarket carbs floating around cheap. 36mm flatslide mikuni`s would work good.

GSXR carbs on 1100

I'm running GSXR carbs on my 83 Kat. It does have an 1150 motor in it but I dont' see a problem running them on the 1100 as I've tryed 36mm 1150 carbs on my 80 1100 with no problems except a rich idle circuit or improper float height.

I'm currently using 90 36mm GSXR 1100 carbs with stage 3 jet kit and dual K&N's. I think you'll run into problems trying to plumb them on a stock 1100 airbox setup.

I had to fiddle a bit with float height as I was told the GSXR carbs are sensitive to float height. I was told to start at 14mm float height but ended up fouling numerous plugs over and over until I set them at 17-18mm. Actually you may have better luck with a Factory jet kit and 14mm may work. I bought a Factory jet kit and tryed to install them in the carbs that had previously housed a Dyno Jet kit and I think the copper emulsion tube that surrounds the needle had been bored out before I bought them. That maybe why I was fouling plugs.

The throttle response was impressive and more immediate with lighter throttle action. The main jets were Dyno Jets equivalent to roughly a 160 Mikuni which seemed a bit big. I'm now running 145's.

Its a bit surgy around 2500-3000 rpms in 2nd and 3rd around town stuff and a delicate throttle hand is required at this low steady rpm. Otherwise its a vast improvement throughout the rpm range. Felt like a new motor was installed the first time I dialed them in right.

I did have to shorten the throttle cable, running a GSXR cable housed in the stock 1100-1150 throttle assembly. I also had the idle speed adjustment screw shortened as it was touching the cam chain tensioner.

I'm running a Pingel petcock with no vaccum line. You also must use a T- fitting to plumb the dual fuel line from the carbs. It's a go if you're into a little fiddling. I don't know anything about accelerator pumps. Carter Turk

I don't have the air box on there. I am currently running the stock carbs with a stage III kit in them with a 4 into 1 yoshi exhaust.
