FOREWORD

This Service Manual is issued as a guide to the complete servicing and repair of the Viper. Venom, MSS, Clubman, and Scrambler models and is intended primarily for the use of Agents and Repairers.
Intentionally omitted are some of the various routine maintenance jobs and adjustments already covered by the Owners' Handbook for the same model as these are usually undertaken by the rider.
References are made in places to special Service Tools which are essential for certain operations. It is earnestly hoped that Agents and Repairers will equip their workshops with them. They avoid the risk of damaging components and save so much labour that their acquisition is well justified.

It is possible that some private owners who are in the habit of doing most of their own repairs will obtain copies of this book. To any of these we suggest that in their own interest they entrust any repairs, which are likely to prove beyond their capacity, to their local Agent and not " bite off more than they can chew."

If you are in any doubt as to the correct method to adopt in carrying out any of the instructions given in this Manual, ask our Technical Staff for help.
The Supplement deals exclusively with the THRUXTON and details the variations to and in substitution of, the instructions given for the Venom Clubman.

WHEN MAKING ANY ENQUIRY RELATING TO THE MACHINE AND WHEN ORDERING SPARES FOR IT 

ALWAYS BE SURE TO QUOTE

 THE ENGINE PREFIX LETTERS AS WELL AS THE SERIAL NUMBER (AND SUFFIX IF ANY). THE VARIOUS MODELS ARE NUMBERED FROM ZERO ONWARDS SO THAT THE NUMERALS ALONE DO NOT IDENTIFY THE TYPE AND THUS ARE IN¬SUFFICIENT ALONE FOR INDICATING THE MODEL
REFERRED TO.
