Author: Floyd Clymer
ISBN: 9781588502421
VP Book ID: 20129
Pages: 140
Dimensions: 8 1/4" x 10 3/4"

Description: 140 pages, and more than 140 illustrations and charts, size 8.25 x 10.75 inches. The original Norton factory “Twin Cylinder” workshop manual contained maintenance and repair data for both the lightweight and heavyweight Norton twins manufactured between 1960 and 1968, including the 750cc Atlas model, which was in production from 1962-1968. As many of the mechanical attributes from the Atlas series were carried over into the early Norton Commando models, we felt that the original “Twin Cylinder” manual was somewhat lacking as it did not include repair data for the early Commando that evolved from the Atlas.

Consequently, we have updated and expanded this Floyd Clymer edition of the original “Twin Cylinder” manual to include the OEM Norton manual (part no. 06-3062) for the 1968-1970 Commando 750cc models that were fitted with the Atlas style exhaust and external rev-counter drive to the timing cover (Beginning with engine no. 126125 – February 1968) and the early camshaft driven contact breaker models (from engine no. 131257 - March 1969). While there is some duplication between the Atlas and Commando repair information, we felt that the Commando manual should be included in its entirety in order to ‘complete’ the coverage of the original “Twin Cylinder” manual from 1960 through the 1970 model year.

It should also be noted that this manual includes significant maintenance and repair information for the AMC Norton/Matchless G15 hybrids that were manufactured from 1963-1967, engine numbers 107388 to 124371.

IMPORTANT NOTE: Many of the reprints found on internet websites are from ‘bedroom sellers’ at enticingly low prices by individuals that really have no idea what they are selling. Many are nothing more than poor quality comb bound photocopies that are scanned and published complete with greasy pages and thumbprints and, as such, are deceptively described as ‘pre-owned’. In addition, they are often advertised for the incorrect series and/or model years of motorcycles. However, has been publishing licensed reprints of motorcycle and automobile manuals since 2003 and our publications have earned excellent reviews worldwide so you can be assured you are purchasing a quality product.

We are pleased to offer this combined reprint of the Factory “Twin Cylinder” and “Commando” (06-3062) Workshop manuals.
