Bike carbs
triumphdave - 17/4/07 at 02:50 PM

I have a set of GSXR bike carbs mounted to a stainless manifold with silicone hose but the diameter on the back of the carbs is only about 12mm long and they keep falling off.Has anyone else had this problem and found a solution.I am using Jubilee clips at the moment but have ordered some of those double wire hose clips to see if they improve things.Not sure what else to do.Its starting to get a bit embarrassing Know having to pull over and pick my carbs up.

is there any way you can attach something to the manifold and then to the carbs to give some extra support?

or fit a tube from split aluminimuium over the host so it goes over the carb bit with a clamp there and some on the other end on the hose.

I don't know whether this adds much but I have GSXR1100 (WP) with mikuni 40's so they may be similar to your set up.

On the bike the rubbers between carbs and manifold are a really tight fit. Lots of WD40 and swearing is the only way to get them on. Then they are held with 8mm wide clamps. They aren't jubilee as the screw is on the outer. Also the original rubbers are short.

I guess your silicone is a bit bigger and slipperier than the original rubbers.

My suggestions. Shorter silicone tubing (less floppy), rough up the inner surface of the silicone tubing (more sticky), score the carb interface, or smaller diameter tubing (more costly!), or tigher jubilee type clips (you can get the Suzuki ones forabout £10 a set, but they aren't really strong and I think in your application you need more strength). You could score the carb outer to give a bit more grip, I don't think you can do any real damage.

At least they are held on with the throttle cable so you don't lose them!

you can get clamps with wider bands - so would be like the ali tube idea I proposed earlier - these would be for larger diameter tubes but of course you can saw them down to length.

My RF900 is very simular to the GSXR-W'
And yes a tight fit but my Rubbers are ribbed.
Thats the Carb rubbers!!
I would suspect straight hose may well fall off.

I am experimenting with this idea at the moment by supergluing an "O" seal.inside the hose.

We have two brackets each consists of two bits of square section and two threaded rods. One bit of square section goes behind the manifold and one goes infront of the TB's the two threaded bars got top and bottom and clamp with nuts.


This sounds interesting.A picture would be helpful,thanks all for the help
