A long shot I know....but does anyone happen to have a spare top cap o-ring for a mikuni carb (FZR400rr). I had 4 when I took them apart but only 3 when I put them back together!!

Thanks
Andy

I've heard of a couple of extra nuts but never not enough caps .... They're back so you might have knocked it off your work surface and it's skulking in the shadows

It's the tiny O ring.
They are not hard to loose,
Next time thread them on a bit copper wire.

ahhh I see.

A Doh-ring

Try Lite Tek Blair

Just looked up litetek....amazing! will email them to see what they can do. Many thanks

Try your local garage, or anywhere you might think will have I-rings in an assortment, sure they will let you have one :-)

They're the really tiny ones about 4 mm outside dia

All sorted now, many thanks. Mr Lite Tek Blair was really helpful, it's a standard size o ring available from most o ring suppliers. Many thanks to all
