I think that's the carb to engine side where they are numbered Roo.

The ones into the air box have the wider section at the top with the narrower part at the bottom so they sit horizontal to the carbs.

Defo no numbers and original rubbers have the pip for alignment. The repro rubbers have no pip BUT you can orientate the rubber keeping the flat sides vertical. New ones, which arrived today are nice and soft - unlike the original ones which are as hard as bullets. The originals were all at different angles, so PO / mechanics was unaware they were installed with a correct angle/orientation.

I see the inlet manifold rubbers are for 1&4 or 2&3 - I bet mine are wrong as well!!

Even if you have long fingers you will find it handy to make a small wooden tool so you can press from the inside of the air box to get all four rubbers in place. When I did my 400 rebuild I fitted it with the rear wheel, mudguard & battery box out it was easy that way.

Matt_Harrington:
Ted, I'll attempt the improvised tool method. I've taken a bike apart before to ensure it all fitted OK but I'm not in the mood to do it this afternoon!  ;D
