FOR SOME REASON I keep hearing of people in the state of New York who are trying to do in all motorcyclists. This time the antagonist is in the state of Iowa, but the New York Times took the trouble to print his statements. As a result, the voice of a recently formed New York motorcycle group provided the answer; a press release from the Metropolitan Cycle Association arrived, pretty well putting the culprit in his place.
I own a '65 Yamaha YDS3C which is driving me slightly nuts. In low gear with any load at all, the bike lurches as if a tooth (or several teeth) were missing somewhere in the gear train. However, 1 have checked out all teeth and they appear perfect.
I read every issue from cover to cover, as do most of my bike riding friends. My question concerns the road test of the Triumph T100R Daytona in the February issue. In the close-up picture of rider and mount, we can all see what the man is clutching with his left hand.
IT would be nice if this column could continue to deal with sport and competition, but once in awhile we must devote some time to the more serious side of motorcycling and the future of our sport. Although the publisher and I are constantly attending meetings and seminars all over the country, usually the reporting of these matters is left to him.
AS ANY SECOND SON will tell us, it's tough to compete with an older and bigger brother, and the game is even tougher when you've got the oldsters pulling for Number One. Such is the dilemma facing the X-5 Suzuki; everyone knows the X-6 is a heck of a guy and the family has formally relegated the smaller sibling to number-two position.
THERE ARE MANY famous quotations dealing with progress and improving the breed. Almost every single one has, at one time or another, been applied to motorcycles. One small Japanese manufacturer could, however, use all of them to describe his latest product and would not be exaggerating a point.
WE AT CYCLE WORLD ARE PLEASED TO PRESENT OUR SECOND GUIDE TO BETTER MOTORCYCLE CLOTHING. THE FIRST HAVING BEEN PUBLISHED A YEAR AGO. OUR REASON FOR REPEATING A SECTION DEVOTED TO FASHIONS IS SIMPLE ENOUGH. THE ENTHUSIASTIC RESPONSE FROM READERS WAS ENOUGH TO WARM THE HEARTS OF EVERYONE HERE AT CW.
Dale Herbrandson, BSME, works in the Advanced Design Division of the McCulloch Corporation and has the enviable task of performing development test programs on all manner of exotic engine designs. He's more than a theoretician, however; he has ridden and worked with motorcycles for some years and prefers to prove his work with operating hardware—to the extent of building his own engines from the ground up. Rarely, if ever, is he without a personal construction project.
GATHERING THE TOOLS
COMBINED EFFECTS OF PISTON AND ROD
SIMPLIFIED ENGINE MODEL
APPLYING THE TOOLS
THERE ARE MANY FORCES present in a simple, single-cylinder engine. The one that makes the engine run is produced by the pressure in the combustion chamber acting on the piston area. This force is divided many ways while being transferred through the workings of the engine.
IF YOU WANT your unit-construction twin to really handle, all you have to do is bolt it into a special frame. If you want your unit-construction twin to really perform, all you have to do is install a power kit and bolt on a splayed head. But if you are looking for both handling and performance, you are bound to discover that the special frame and the splayed head have a mighty poor.
CYCLE WORLD TALKS WITH THE INVENTOR OF THE SHOE WORTH FIVE SECONDS A LAP.
AMERICAN FLAT TRACK racing is such exciting sport that one tends to forget those lopsided gladiators are on the oval, not only to entertain, but to go fast. Behind the wire fence, underneath the floodlit layers of dust and almost visible emanations of popping and banging, there are the quiet bits and pieces of metal and rubber that make it all work.
THE LATEST INSTALLMENT of what is fast becoming the CYCLE WORLD serial on famous ISDT tiddlers finds us with the machine — or select pieces of it anyway — on which U. S. desert rat and Baja king Dave Ekins won a gold medal in last autumn's International Six Day Trial in Sweden.
A comprehensive guide to touring Europe by motorcycle might occupy a large volume or even more. This bulletin does not purport to offer more than general information and some useful facts. Notwithstanding, it should prove of much assistance to those considering a two-wheeled journey in Europe and to provide shortcuts to obtaining further and more detailed information.
THERE ARE MORE things coming out of Switzerland these days than cheese and watches. For the third straight year, Zürich has presented an international bicycle and motorcycle exhibit that earns for it a place on the world motorcycle map. Some 20 manufacturers from 10 countries filled three floors of Züspa Hall, with everything from bicycle pedals to a 700cc V-twin Moto Guzzi.
IF A PERSON can break away from the slot machines and roulette wheels long enough, Las Vegas is a great place to go racing. In fact, with so many distractions about the place, it is difficult to find time for sleep. Most of the riders, however, did manage to tear themselves away from the festivities early enough to be in top form to master the three-mile, superfast Stardust Raceway course, where motorcycles were competing for the first time.
THE SAGA OF THE ARMER ELECTRIC. TOM SWIFT RIDES AGAIN
THE AMUSED EXPRESSION On the clerk's face deepened to a perplexed scowl as he searched yet another page of the licensing regulations in an effort to come up with a ruling to cover electric motorcycles. Finally, he was forced to sell Rollin Armer, of Berkeley, California, a "Homemade Vehicle" registration tag, but had to arbitrarily tack on a ten-dollar Road Use Tax, usually contained in the price of gasoline in California.
One of the most interesting events on the snow-drifted Eastern winter calendar is the Crotona Midnight Run — which is to motorcycling road riders what an all-night TSD rally is to the sports car set. The run was started in the infant years of motorcycling as a way for the hardy few belt drive-acetylene types to celebrate the coming of the New Year, regardless of the weather.
MOTOR RACING in the U. S. has had more than its share of improbable machinery doing incredible things — go-karts that lap short road circuits faster than full-size sports cars, VWs that run 150 mph in a standing start quarter mile, and now disc-wheel motor scooters that "best" lightweight trail bikes over terrain that would inspire caution in a bighorn sheep.
AT LAST WE are able to offer the first (and only, for that matter) motorcycle service manual ever produced. A statement which should partially overrule most objections to the book, since it is the one and only, to date. It's 240 pages thick, printed on nice, glossy paper, and worth every penny of the five buck plus price.
VIBRATION MODES OF TWO & FOUR CYCLE SINGLE & DUAL CYLINDER ENGINES.
THE RESULTS OF WORK PERFORMED BY PETER E. WIKOFF, WILMINGTON COLLEGE, WILMINGTON, OHIO.
PETER EARL WIKOFF
Peter Wikoff of Geneva on the Lake, Ohio, spent considerable time in his application of vibration modes of engines to motorcycles. He is naturally an avid motorcyclist, having begun "when I was still considered a hood." This article is written through his research in astronomical photometry and laser development and construction.
Leseo Motorcycle Accessories, a mail order firm for the retail buyer, has issued a new catalog which looks just like the first one up front. But things therein are meatier than ever before. Leseo is now an authorized retail mail order dealer for the famous line of Webco accessories, as well as Hap Jones, Tabloc, Motorcycle Supply, ASC, and Sammy Tanner Distributing.
FOLLOWING TESTS at the Hamamatsu circuit in Japan on both the 125 and 50cc machines, Stuart Graham has been signed by Suzuki for the 1967 season, so the Japanese two-stroke concern now has a team of three for the classics. This includes Graham, world 50cc champion Hans Georg Anscheidt, and Yoshimo Katayama.
AS ALREADY PREVIEWED in this Space, Milanese engineer Daniele Fontana — well-known for his fabulous FD racing brakes — is building a three-cylinder 500cc racer for privateers which should soon debut in the hands of either Jack Findlay or Alberto Pagani.
JAPAN'S MOTORCYCLE manufacturers have decided that the 175 to 200cc class is going to he the next one to catch on and become a best seller, and all of the big five makers have announced entries in this size. Biggest selling point is that these bikes are large enough and have sufficient power and speed to give a "big bike feel."
