As though in answer to my insistence on what the motorcycle industry needed most, the American Motor Scooter Association in a San Francisco meeting and conference, changed their name to the American Motor Cycle and Scooter Association.
IN THIS COLUMN, two months ago, I promised additional details about the modifications made to the Honda engine in my Cotton Telstar road racing bike. As it happens, we (my good friend, associate and "tuner," Brian Crawford, and myself) have more development work to do than was envisioned at the end of the 1964 racing season.
I own a 1964 Matchless G80 CSR. I want to run an open exhaust system. Using a 440 main jet, with plug, points and rocker clearances correctly set, I get tremendous acceleration from standstill, but when cracking the throttle wide open from a 40 mph idle, the machine "dogs" and "coughs" giving no go whatsoever.
I want to thank you for the great job that you have been doing. A few years back I wrote to one of your competitors about bringing out a decent motorcycle magazine. I told him that to many, motorcycles were just pictures in books and that their road tests were like advertisements.
MOST MOTORCYCLES have an indefinable something we call "character," and because they have this quality, they also almost invariably acquire appropriate names. We do not know what the average Royal Enfield Interceptor owner is calling his machine these days; but we would offer "King Kong" as a suggestion.
WHEN Eric Dahlstrom won outright the November 8th 350cc road race at Southern California's Willow Springs Raceway and was beaten in the 500cc event only by a trio of well-prepared Norton Manxes, his triumph was one of double importance.
EXACTLY ONE YEAR AGO, we tested the James Cotswold 250, which was then powered with a Parkinson-conversion equipped Villiers 36A engine. It impressed us as being quite a good machine, but with a couple of disadvantages. One was the ear-drum shattering racket from its open stub-megaphone exhaust system; the other was the very puny brakes — which could hardly be considered adequate for even a scrambler, and scramblers do not work their brakes very hard.
AFTER SEEING the Ducati Portable and mentioning it briefly (Around The Industry, CW December, 1964), we were of course impressed with the newest and smallest member of the Ducati line of machines. Ducati now comprises a range of motorcycles from 50cc, the portable, to 1260cc, the new Ducati/Berliner four.
RIDERS OF motorcycles have one thing in common with the four-wheeled set — an occasional urge to go camping or cross-country touring. But although they have the advantage, especially with trail bikes, of getting into areas not accessible to the four-wheelers, they are at a disadvantage when it comes to carrying gear.
FOURTEEN MEN, gunsmiths by trade, sat around a long boardroom table in Birmingham, England and watched as Mr. E. Otto prepared to demonstrate his invention — a bicycle. In 1861, the gunsmiths had formed the Birmingham Small Arms Company and as the musket business had been poor in 1880, they were looking about for a new item to produce.
Norton frame, water-pump engine, and $200.00 produces an interesting drag experiment.

HOW DO YOU BUILD a successful drag machine for $200.00? Rick Vesco, an eighteen-year-old high school senior from San Diego, California could tell you how because he has done it. Desire to "go fast" combined with a limited budget were the two main factors that forced Rick to spawn the idea for this unusual machine.
FORCED AIR is one of the more modern technologies being applied to the heating of private residences these days, and it is also one of the latest methods of cooling motorcycle engines. We are not saying it is anything new, even the popularly-used chain saw avails itself of this method of cooling, but it is rarely found on a motorcycle or scooter.

HAVE YOU EVER ridden your own cycle tensely along a city street in heavy traffic and watched a fellow motorcyclist cruise serenely by with a happy look on his face? Chances are excellent that he was wearing an approved helmet, was neatly attired in jacket, gloves and other suitable riding gear and was aboard a sparkling and smooth-running machine.
YAMAHA'S TD-1 "production" road racing machine, which is a development of the 250cc Yamaha touring twin, has for a long time been one of the better bikes available at reasonable cost to the amateur racer. It has superb brakes, good handling, plenty of power and a 5-speed transmission.
ONLY ONE motorcycle firm in Germany today races factory road race machinery, but Kreidler of Stuttgart are in the big-time all the way. Their competition history is almost classic: start with hoppedup production machines, discover yod need full-house specials, knock off a brace or so of class records — then build a production racer for the customers?
THIS MAY SOUND like an ad for a finance company but being a working stiff and a squanderer of money, my means of getting cash for the journey was to run down to the bank for a three hundred dollar travel loan. It was Friday and the last day of January when I set out from my home in the little town of Sonora in Northern California's Mother Lode country.
To: Motorcycle International Committee of the U.S. (MICUS) From: Club Union Motociclista, Jose A. Cabrera 4027bis, Montevideo, Uruguay. After having tried in 1964 to enter our riders in the Grand Prix of USA, sending four (4) different letters to MICUS without receiving any reply, for this year 1965 we have:
Often finding themselves short of merchandise during 1964 because of the great increase in the U.S. sales of motorcycles, Cosmopolitan Motors searched the world market to obtain additional supplies for 1965. The Luigi Benelli firm in Pesaro, Italy was also looking for an experienced distributing firm to handle their products in the U.S.
BOTH SUZUKI and Yamaha are reported to be rushing work on sports models in the 65cc class. Honda got the jump on them, and already have a 65cc sports and a "nifty fifty" style step-through 65cc on the market. Again, as with the 55cc and 60cc bored out versions of 50cc machines, the licensing laws in Japan are the cause of this new class.
THE OFTEN RUMORED and highly speculative 500cc Honda production machine is now a reality, as indeed it always has been. Shown here for the first time in these secretly obtained telephoto photographs is the prototype of the new machine. Though reports are that it will be of 450cc displacement, or 27.3 cubic inches, it will more than likely be called a 500.
THE MOURNED PASSING of larger capacity four-stroke "bog wheelers" in last month's column seems to have been a little premature, for Jeff Smith has been out on a Victor-engined trials machine which was virtually a moto-cross model with a low compression piston.
TWO-STROKE disc rotary valve engines for go-karts have been built by various Italian factories for some years, but interest in this appealing, high performance type of engine in the motorcycle field only started about a year and a half ago.
MOST DAILY PAPERS carry round-ups of sporting achievements for 1964, and the Toronto ones listed about every kind of sport from bronco-busting to hockey, but didn't give their local boy, Mike Duff, even a mention. It seems to be a hard fact to face that there are "in" sports and the other kind.
