BSA Illustrated Workshop Manual
500cc OHV 650cc OHV Twin Cylinder
Rigid and Plunger Rear Ends
All Years

This manual was reconstructed from a photocopy BSA workshop manual using scanning and OCR (Optical Character Recognition) software to transfer the text and images into a word processing program. The layout and chapter structure was then modified to suit modern documentation style before final proof reading was carried out.

The photocopy manual appears to be made up of a compilation of BSA service sheets and other contemporary resources.

A PDF version of this manual is freely available to subscribers to this WIKI.

UPDATE -  21 March 2023

Site now upgraded to Joomla 4
This site is built on the Open Source Joomla Content Management System.
Joomla 3 is no longer receiving security updates, forcing me to migrate to Joomla 4.
Joomla 4 has  flexibility "out of the box" so the wiki is now compatible with mobile devices .
A lot of the older content  still contains styling and media more suited to the original fixed web design but I will hopefully be trawling through it and cleaning it up. 



UPDATE -  11 April 2015

After  more than 6 years and 152,000 page views
the original mediawiki software version that powered this site has become obsolete.

So I am pleased to announce that
bsawiki.co.uk has been successfully migrated to
Joomla 3.4.1 Content Management System

Look out for further improvements coming soon!!
