I am fitting an aftermarket silencer (though near identical to original).
Problem is the rubber stop to the centre stand needs inserting in the silencer bracket.
The stop - where it goes in the bracket - is conical shaped, but at its narrowest point is about the same diameter as the hole. It is simply too big & wide to go in.
I have tried heating it in boiling water to make it more pliable and also using washing up liquid as a lubricant but to no avail.

I know one or two people have fitted these silencers and wondered if there was an easy way to do this -
(apart from filing the rubber down to make it smaller!.)
Cheers
Kevin
