Bonding aluminium
I have had my bike carbs on the Westy for a few weeks and have never really been happy with the way in which the hose connects the bike carbs to the
inlet manifold (issues with the silicone hose sliding of the small stub on the carbs).So what i wanted to do was bond slightly longer pieces of ali
tube on to the outlet of the carbs so there is a bit more length for the hose and clip to bite onto without twisting off.I was going to use Sikaflex
221 and wondered if any one had any experience of using this or something similar.
Thanks in advance Sean.

The silicon hose and petrol have a poor working relationship.
There is a few examples of bike carb sets falling off
perhaps a differant hose type my be the answer and maybe some stays with antivibration bobbins to support the carb set.

Best way to secure is to use alloy straps fitted from head to carbs. If you look in my photo archive you will see what i used.

As mango says, silicon is not suitable with petrol, unless it's lined with hydrocarbon elastomer, such as Samco Pro-fuel hose. I would change it
for a suitable hose before I used the car again

If it helps i super glued the rubber hose on the carbs before J / clipping use narrow clips

Have you tried the original rubber link pipes from bike, they have little cut outs which locate on those little pins on your on your carbs
