Head Lamp Stay Rubber Grommet CB750F - Alternative replacements?

That’s a good idea ! Nice one, just need to get a new batch of Stanley knife blades, less chance of accidents. Doing the inner hole might be tricky, but I could do that first, might be able to drill it. Then paring it down to fit.

Oddjob:
Drill it, should already be a screw hole central in it. Or screw a long screw in it, put the screw in a drill and spin the rubber, you should be able to sand it down with rough then smooth sandpaper or even a sharp chisel, then drill the hole last.

McCabe-Thiele (Ted):
I burn holes in rubber using a slightly narrower bit shaft - often it's not straight rubber but a plasticy type material. I put drill bit in vice warm with my blow torch until it well hot. I use a plumbers heat mat to hold rubber as I burn the hole.

Pedro26:
I got these from Homebase. They’re not solid rubber, but that is an advantage. 2nd attempt was successful I cut off the lower part just to where the main hole ‘bottoms’, without cutting into the rubber for the larger hole’s base,  then pared away around the sides until the top disc was sufficiently thin, which is just a tad below the actual original shoulder. Also if you leave too much of the door stop’s strengthening walls, it works against you, even though the rods fit the hole as if it was made for this, (no drilling required) and they fit into the fork bracket hole.  Too much rubber round the lower periphery on the newly fashioned grommet, and you struggle to line up the top holes of the stays, where the speedo/tachometers bracket mounts with those threaded pins.

Anyway, result. First result is in the photo, successful one is on the bike, shorter in overall length/depth than the one shown.
