I'm having trouble with some zx750 bike carbs. The flange on the rear of the carbs is so short that I am struggling to get the silicaone hose and
Hose Clip to Stay on. I get them on and tighten up the hose clip and it will pull the pip off the lip. 
what can I do. O when running on idle the
suction is manageing to pull in the silicone hose and pull it off the flange.
I have just cut lengths of silicone hose and used that. Surly bike must have a better fitting. Where do you get those green hoses Bogg borthhers
use?
Other problem I have is when running the carbs "bounce" about a good bit
Mine bounce about. I have a bogg bros set and they have thing jubilee clips on.
When I was constructing my manifold I saw some similar post so I used the original bike inlet rubbers mounted onto plates welded to the tubes. They
have ribs on the inside the grip the grooves on the carbs. Just done a track day and had no problems in 90 miles.

I've fab'd a pair of stabiliser brackets, to try and replicate the stabilising effect the airbox has when installed on the bike:

Had to make some stabiliser brackets for my TBs , was able to drill and tap the manifold flange to bolt them on and used a couple of tapped holes in the TBs Been OK for a year now. Silicon hose isn't the best stuff to use for carbs or TBs
Supper glue the rubber pipe to the carbs then j/clip, that is what i have done had NO problems and they have been onabout 2 years know

What can I use istead of silicone hose (dia is about 46mm)
My carbs are GSXR750 what are suitable "inlet rubbers"
I'm using the 45mm version of THIS
You could consider using stainless exhaust clamps instead of jubilee clips. You can do them a hell of a lot tighter. Like these:
I'd recommend using fuel hose as above. Silicone isn't fuel resistant generally and the rubber stuff probably has higher friction.

OK, not carbs, but I made up some brackets for my Bike TB's to hold them on, It still allows a little bit of flex.....

This is one of the pipes from my inlet manifold, just before it was welded.
You can see the groove where the bike carb connecting rubber locates.

I have Honda Fireblade carbs on my Skoda Estelle trials car. I had the inlet pipes made up locally and welded to my own made manifold plate. The pipes used had to be sleeved to fit the bike rubbers and didnt have any grooves in them. I made up mounting grackets rather like the plates in the photos, using the cross shaft that secures all the carbs together in one line and fitting on to a manifold stud at each end. 7,500 rpm and bouncing up and down a variety of rough tracks did nothing to dislodge them. RESULT!!!
My manifold has groove cut in end of pipes.
I had same bother when using silicon - found it went mushy / slippy. Changed hose and no trouble since. Still have some hose left.
