thanks to all for their replies to my query about synthetic oils.

the basic conclusion that i have come to from a talk to the person
in charge of the service department where i take my bike (which was
corroborated (sp?) by one or more replies) is that it is not a good
idea to switch over to a synthetic oil after having used a regular
oil previously for any period of time (including the break in period).
the reasoning is that regular oil creates a thicker film around things
and when you switch to the synthetic it creates a thinner film and so
things tend ``rattle around'' a bit more, also oil consumption can go
up because of this. the shop manager said that it is best to stick to
whatever oil the bike was broken in with; remember this if you want to
use some oil fancier than the dealer puts in the bike when they sell
it to you.

so, presumably if one started using a synthetic as soon as they bought
the bike (brand new) they might be able to. although one or more
person mentioned that because synthetic oils are more slippery that
they can cause problems with transmissions/clutches in motorcycles.

anyhow, i'll stick with good 'ol castrol.
