500 air box intake rubbers

[Giles C]

Hi all,
My rubbers have seen better days, I can fix them with self amalgamating rubber tape but I would loose the crank breather link.
What is that for and is it important?
Also, does anyone have a link to a supplier for these parts?
Thanks a lot
Giles

The connecting rubbers haven't been available for decades... just fitted my very last new set to wifeys' 500.

The breather connection was made for emissions reasons, no nasty oil fumes in the atmosphere, they have to take the detour through the combustion chambers!
