Thanks very much for the link. It's just what I need, especially the photos/glossary of exactly what is what. Excellent.
(Don't know why I didn't think to look in that forum originally). I really need beginners stuff, i.e applicable to a general motorbike, rather than one particular make or model.

Your welcome: I was not sure where to put a post with a link when I first came across that site and, going by the number of responses to that post, it has not been very visible; I have suggested to Grant in the web feedback section that it could be included as a more high profile link in his website - but that's up to him of course.
Glad you have found it useful!
