Silicone for mounting bike carbs?
FASTdan - 12/2/10 at 12:59 PM

What are peoples experience of this? I've read varying reports from the silicone pipe being fine after 2+ years, whilst others claiming after 1000 miles the silicone degrades and the carbs start to drop.....

I'd be interested in people's responces, too.

I've used blue silicon hose on my inlet manifold for my carbs, but it's the reinforced stuff designed to carry oil.

I understand that there may be issues surrounding it's use for IVA purposes as well - mainly in proving that it is suitable for the task. Anyone been through IVA yet with this setup?

I would also be worried if you plan to find a lambda sensor, as they do not like silicone products....!

I used the original bike's rubber tubes...

i have the blue silicone , but not sure of the type as purchased via chester sports cars with manifold /carbs/megajolt

It wasn't mentioned at IVA.
Although I have failed on other items.

I don't think it would fail on that. My worry would be are they petrol proof, I doubt they are and as others have said silicone and lamba sensor is not a good idea (maybe in the fresh air side it's o.k as the silicone will not get washed though as there is no fuel to do that)..

Interesting - didnt know that about lambda sensors - what does it do to them?

silicon kills them. Remember the tesco fuel chaos a year or two ago, silicone in the petrol did it.
I would avoid anything unless specifically labelled petrol proof.
A friends RS500 lunched its fuel pump 3 days after he fitted a bit of silicone hose that he was told "probably OK" for fuel. The pump was full of bits of blue hose
Of course, you may wish to save a few bob and risk it, you may be OK. However, for a few quid? not worth the risk

most hose places will sell silicone hose that works for fuel

I'm one of the ones that it keeps falling to bits on...

Even fluoro lined silicone hose is not resistant to continuous contact with fuel.
