Anyone recognise this bit?

[Alan B]

I've had the back wheel out to grease bearings, check belt and pulleys, and the petrol tank off. Put it back together and spotted this rubber stop on the garage floor. I don't recognise it and I've re-checked what I've done. It all looks O/K. It's the usual thing I don't remember seeing it but could well be off something else all together. If I've posted the picture correctly it's about 1"" long with a slot in it. Could be a stopper.

Alan,

Can't say I recognise it, not from tank, and I don't think it comes from the rear wheel area.

How did you get the back wheel off the floor? Could it be part of your bike lift?

[Alan B]

No it's not off the lift. Its probably fallen off the shelve when I picked something up but it's the not knowing that does you.
