[AJD] Researching options

[Kevin Smolkowski]

I decided to build a companion page to my www.twocylinderdiesel.com page
for MC's (since a have a few of those as well).   There isn't as much
litature out there as I was able to find on the diesels.

I have all the manuals and some brochures, is there any more info out
there on the MC?   How does one do research on what changes were made
when, is it just looking through the parts book and noting what changes
were made at what serial number and trying to group them into some sort
of meaningful history?
