We have been claiming for some time to be publishing America's largest selling motorcycle magazine; the gentleman seated on the sparkling BMW recently visited our offices for a week of proving that statement. He is Larry Kemmer, and he is a field auditor for the best known circulation auditing firm in the United States, ABC, or Audit Bureau of Circulations.
I have a 1953 Harley-Davidson 74 on which I would like to install dual carburetors. However, I am not sure just how to go about it. Would it be better to have a separate manifold for each cylinder, or to install both carburetors on a single manifold?
THE MOST ENJOYABLE bit of work that a benevolent fate has ever brought us was the double-barreled test of Yamaha's sports/touring YDS-2 and road racing TD-1. These machines are quite similar in general layout, and specification, and yet their characters vary considerably, the only strong point of similarity being that both of them do that for which they are intended in a truly magnificent manner.
The effects of cylinder dimensions on power and torque.

OLD WIVES' TALES abound in any field of interest, and motorcycling is no exception. Much of the information that the average enthusiast hears, and accepts without question is likely to prove, on close examination, to be only half true, or to have no basis in fact what-soever.
THERE IS A CERTAIN FASCINATION in owning a machine that is unique in America, and when Terry Buffum of Palo Alto, California, saw a 250cc factory racing Adler advertised for sale in a German magazine, he cast caution aside and bought it forthwith.
THE MORNING SUN smiled brightly on the 25th Anniversary running of the Sandy Lane 125-Mile National Championship Enduro near Camden, New Jersey. Many outstanding riders were among the 117 contestants at the starting point — such top names as Jack Wright, last year's Sandy Lane winner and high point man at the recent Jack Pine Endurance Run; Bill Baird, a well-known enduro rider from the midwest, and John Penton, who won in 1960 when the Sandy Lane was a 200-mile event.
A LOT OF TIME HAS ELAPSED since the 1914 Excelsior was built, but it was a very interesting machine indeed. The bike shown here, part of the William Harrah museum collection in Reno, Nevada, is a 1914 chain drive, 61 cubic inch, V-twin.
THE THIRD ANNUAL East-West scrambles meet, held in California this time, ended in decisive victory for the West Coast riders, with BSA-mounted Don Spargur the top overall point scorer. Other talented members of the high-point team were Eddie Mulder, Bruce Jackson and Skip Van Leeuwen.
WINDING up completely clutchless and practically brakeless, Dick Dorresteyn rode a brilliantly-paced race to win his second national Tourist Trophy championship, the Ascot 50-lapper promoted by J. C. Agajanian and televised nationally by ABC's “Wide World of Sports."
SATURDAY WAS THE DAY of practicing. Rain had made the circuit surface slippery, but the riders pressed on in spite of it. Not all were too pleased with the course — some felt that it was too narrow. One of the riders who had troubles was 1962 World Champion of the 500cc class, Mike Hailwood, who fell off a 125cc MZ and felt so badly that he decided not to start on Sunday.
JACK WHITE, of White Motors, Maico Distributors in Costa Mesa, California, has come up with what we think is one of the most interesting approaches to the trail bike scene we have found. The Maico Trailster is the result of a recipe White created in answer to the growing trailing enthusiasm that is composed of several fascinating elements.
THE 50 CUBIC CENTIMETFR displacement cycle world grows more interesting by the day, thanks to such additions as this month's candidate for supremacy, the Japanese built Tohatsu. We have been hearing of various successes of this recent entry for quite some time, most of it very good news for the Hap Jones Distributing Co. in San Francisco, distributors for the line.
A UNIQUE FOUR-HOUR team race for 250cc production machines was presented recently at the 1.3 mile Vineland, New Jersey road race course, with sixty riders competing on thiry standard lightweight road models, fully equipped with generators and lights.
A FEW STUTTERING CRACKLES and then the full-throated song of the Gilera four broke the still quiet air of Oulton Park the day before the Bob McIntyre memorial meeting, for Geoff Duke was there to do a few practice laps on the machine he had not ridden since 1957.
Now THAT the establishment of the JB Matchless Corp. in Hasbrouck Heights, N.J. is complete, Matchless dealers all over the USA can anticipate that parts for new, current and older models will become available. The parts department is already in operation and 1963 Matchless models will be available to franchised dealers in the USA late in December, according to Walt Von Schonfeld, Advertising Mgr. and Director of Public Relations for the newly-formed JB Matchless Corp.
You MAY REMEMBER that last month I mentioned the trend in the sport which seemed to be the end of the 500cc class because of two factors. The first of these was the possible end of production of the big Matchless and Manx Norton machines and the second the very high speeds that this class was now producing.
THE CANADIAN National Championship Hill climb was a U.S.A. benefit, as riders from south of the border took all the titles. Willard Bryan, Groveport, Ohio won the Class A on a BSA, while in the Class B Bobby Johnson of Columbus, Ohio made the fastest time of the day at 4.54 secs. on his Harley 45.
It has come to my attention that in the road test of our XLCH in the October CYCLE WORLD a small gremlin has been at work. It seems as though someone gave your Editors some misinformation as to the type of clutch used in this machine. You will note under the specifications page under "Power Transmission", it calls for a multi-disc wetplate clutch.
GREATEST ALL-AROUND RIDER of the last decade, Joe Leonard has been plagued by ill fortune in every national championship race he's entered this year. This will be the first season in the last nine that he has not finished third or better in point standings, and he carried the Grand National Champion's Number One plate for three of those years — 1954, 1956 and 1957 — winding up in second in 1958, 1960 and 1961.
A LITTLE OVER A YEAR AGO, Ernst Degner was an East German national figure as the leader of the M.Z. road racing team. In 1960 he had won Grands Prix in Belgium and East Germany and his success in 1961 was such that he started the season with a second place in the Spanish G.P., won the West German at Hockenheim, was second in the French but struck disaster in the Dutch for a practice crash broke his elbow.
