Fluoro lined silicone hose
do i really need to use fluoro lined silicone hose to go from my bike carbs to inlet manifold?
i think i probably should but its so expensive!!!
i need 42mm I/D does anyone have 160mm spare i can buy?
or would anyone be interested in buying some off me if i bought a full 1000mm length?
id only charge you cost price plus a couple of £s for postage
its just im not going to need a meter i only need 16cm or 4x40mm and it costs about £40 for a meter

No you dont have to use fluoro lined hose, plain silicon degrades rapidly. I used black rubber water hose which is about £8 metre and have not
replaced it in 5 years so far.

I will measure my throttle bodies & let you know, if its the same size then i would buy 4 short stubbs off you.
I have standard silicone to go on them at the moment but the the lined stuff would be better.

Silicone hose is also a lot more likely to slip off than rubber,

My 40mm kits listed on ebay will easily stretch to 42mm - and with a bit of stretch and the narrow hose clips they give a very firm grip.

If you can find some of a suitable diamater, fuel proof rubber hoses are a much better solution than silicone. It grips better onto metal and is
tougher and is less easily damaged. If going for silicone then fluoro lined is the one to go for as normal stuff isn't fuel resistant (and even
fluoro lined hose is not usually rated for continuous contact with petrol).

Correctly sized fluoro lined silicone coupled with correctly sized hose clips does not slip off......instances of which are a result of poorly made
misaligned manifolds and/or badly sized silicone/clip combinations.
A few points - sorry if this is stating the obvious but unfortunately silicone mountings often get a bad rep - most of which is down to skewed
manifolds and long buldging baggy hoses used to overcome alignment.....
The manifold tubes need to be parallel and spaced to match the carbs - tubes that are not parallel with the carbs just try to pull the hoses off the
carb body.
9mm wide bands should be used on the carb side. 12mm wide bands are too big for the carb end and simply try to squeeze the hose off the chamfered carb
body.
Hose size should be snug or stretched ideally. Compressing down by 1-2mm can work but avoid if possible.
'Free length' of the hose (ie the bit between manifold and carb) should be kept to a minimum. Our kits are 50mm hose lengths which offer a
small amount of flexibility for trimming etc should it be desired.
