I have bought two different manufacturer top end gasket sets for my two 550s and both are missing the 6off "lozenge" rubber sealing washers that cover the access to the head nuts. Is this normal as they include the large wavy O ring for the cover itself? It is annoying as the they seem to be over £3 each, unless somebody knows otherwise.
Should they always be replaced?
I have some from a set from a 500 that I did a dozen years ago and I'm sure they were included. At least I'm OK for one bike.
Thanks
