MOTOR-CYCLING

MOTOR CYCLE NOTES. When away from home and. touring the country carry a lOit or 12ft longtn of 'i.ojlit rope to use: as a tow line in case of emergencies. It is often a good itba to cany « medium-sized adjustable-spanner in i liecoat- of vour over-alls when touring. J.'his mav save undoing the tool bag several times. The first motor-cycle football match in Spain was played this year between Barcelona, clubs, and excited so muon interest that the Motorista Club Rarcelonia has decided to encourage the sport, and is forming, teams to compete during tine coming winterPLUGS. The modern motor-cycle engine, which is a high efficiency unit, is not iniretiuentlv fastidious in its taste as regarde the mtter of .sparking plugs. On older machines and on a good many motor cars it does not very much matter what plugs are fitted, but with most of the faster eye'e engine® it ~s essential to use a plug that really suits- it unless constant and somewhat expensive trouble is to be experienced. A difficulty that arises in connection with this matter is that garages keep, in manv cases, but restricted stocks of plugs. They may sell the make that one wants, but their supplies are often limited to one model only, and that, as a rule, not one thaii Is particular 1 y well suited to a really “hot-stuff” engima. Most of ns have at one time or another failed to obtain the plugs that we wanted on the road, and for the rider setling out on a lpngthy tour the obvious thino- to do is to carry with him at least one- spare plug or more if his engine is likely to need thorn. OVERHEAD CAM-SHAFT;?. At the present time so much interest centres round the question oi overhead cam-shaft® for motor engines that some consideration of the problem involved i® well merited. . A glance at the many forms of drivin# gear in -existence is? .sufficiont to show that, up to the present time, there is no unanimity a® -regards .the probable solution: yet all the designs reveal an effort to achieve the same J which is to lighten the reciprocating masses in the valve gear, with the eonseement reduction of -stresses m these vital parts. On,' 1 - of the first motor-cycles to reach the hands of th? Buying pub.ic in cam-shaft form was the Velooette. - and this machine has a vertical «liatt with a bevel drive at each end. At-the moment this is- the most popular type of drive, for, in addition to the Velo- < ette i t is adonted hv the designers of the Norton, Oalthorpe, Atlanta and Guzzi. although details vary in each m&Q. —— —mmmm
