Gs1100 (1980) Carb,s

[Colin]

Hi hope someone can tell me if what I'm trying to do will work.
I have a GS1100 (1980 reg) and I want to change the carb's for larger one's, (38-40mm). I've been told that early gsxr's carb's will fit but I have noticed that these sit on the gsxr's engine at a angle with the float bowl level.
My quistion is if I fit these to my engine the carb's are up-right with the float bowl's at an angle, would they still work as they should do.:?

I do believe the 88-91 GSXR1100s had the 38s. They will bolt on with K&N filters.
Jetting required of course.

It was actually the '91-92 750's that came with the 38's in the U.S., 1100's came with 36's. I think the Canadian 750's came with the 40's. You will have to angle the carbs towards the engine using a to level out the float bowls and reset the floats a little lower. However you may have an issue with the carb boots as they will have to stretch pretty wide to accept the 38's. I doubt the 40's will fit unless you switch to a '91-'92 GSXR 750 head (got one for sale great shape with the valve cover, no cams, cheap, PM me). I tried to get a set of the GSXR 36's to work on my bike but never could get them to my satisfaction. Other folks on this website have made them work however.

Thanks for clearing that up RJ. I was selling those carbs on Fleabay a few years ago but forgot the details.
Wanna buy a 17 inch rim? \\/
