I've assembled a reference document for myself and thought maybe the community would find it useful as well. It's essentially an improved Buddy 125 parts diagram. After each assembly diagram is a list that describes what each part is. I've found this really useful for identifying pieces of my scooter. Here's a screenshot of a random page, so you can get an idea of what it looks like: http://i.imgur.com/NMzloGC.png
<facepalm> I must have looked at that Excel spreadsheet a dozen times over the past few years, but never made the connection that it was referencing the parts assembly diagram. D'oh!
I think I'll update my doc to reflect this, that way it will be around if anyone wants it. Will post a link to the updated document once it's ready.
