Fitting Speedometer rubber in "Divers Helmet" query ?

[iansoady]

I always use a drop of petrol for footrest and handlebar rubbers. Swill it around inside then the rubber slips on very easily. The petrol evaporates after a few seconds and all is secure.

There's at least two types of rubber mounts - a good soft pliable one, and a bad hard rubber one. The soft one has a more of a matt finish when compared to the shiny hard one. The soft one is 'fairly' easy to fit, it took me several attempts and some washing up liquid. The hard one I found impossible, and gave it away to a falcone owner who needed something about that size. I got the good one from Gagg and Sons.
