IT’S TIME to make it official; the 1967 Fifth Annual CYCLE WORLD Motorcycle Show date is June 2nd, 3rd and 4th. Almost 100,000 people paraded through the magnificent Los Angeles Memorial Sports Arena for the 1966 show, and we fully expect over that number for this year’s stellar event.
IT is the time of year when the keen types start thinking of Daytona, our largest, best supported “classic.” Largest, because it has become a traditional part of American racing; best supported, probably because of all the northerners looking for some warm sunshine after the months of ice and snow.
I own a 1965 Honda Dream 305 and it has 3,100 miles on it. I would like to know how to stop an oil leak at the front of the right cylinder where the points are located. Oil seeps out just enough to foul the points at about 500-mile intervals. Arthur Gallant Portland, Maine The oil leak is almost certainly caused by a defective contact breaker plate housing oil seal.
I used to be what you would term a “bum.” I had 20-inch risers on my Bonneville, I wore a large Maltese cross, and behaved in a manner typical of the Hell’s Angels. My group and I would get 75 percent drunk and ride en masse down the main street of the small southern town we frequented, with our open pipes making a terrible racket, and anyone we encountered was smothered in obscenities.
THE BIG RACE among Japanese motorcycle manufacturers as to who would have a quality 350cc machine in the U.S. has finally been won by Yamaha. Factory designation is YR1, but to Americans the name Grand Prix will undoubtedly become more meaningful and easy to remember.
THE MASK IS OFF. Now we know why Paul Friedrichs, Joel Robert, Dave Bickers and Victor Arbekov go so fast; they ride CZ 360s. If ever there was a bike to make child’s play of scrambles, this is the item. We waited for several months to get our hands on “superbike” and since we are accustomed to being entrusted with exotic iron, we conjured up all sorts of wondrous images of ourselves romping off into the hinterlands on a single-pipe CZ 360 Motocross.
TESTING A SCRAMBLER and an enduro bike in one fell swoop may first strike the reader as a good way to shortchange both. In the case of these two 360cc machines from the West German firm of Maico it works out fine, as the bikes are similar and the presence of one helps explain the other.
ALIGHT RAIN begins to fall into the dark night air. Just a few wet drops splattering on dry leaves, tinkling on trash can tops and plopping on a glossy motorcycle. It shouldn’t be enough to wake him up, and normally it wouldn’t be, but tonight Arthur and sleep can’t seem to unite.
THE TWO MASS record attempts held in Britain recently showed how far British sprint (drag racing) machinery has developed in the last couple of years. Much of the progress is due to American influence, for visits paid to Britain by members of the American drag festival teams in 1964 and 1965 taught English riders two things: the clutch is pretty much an ornament and nitro-based fuels can work miracles.
IN CROSS-COUNTRY RACING the 100cc “trail-bike” class has firmly taken root and despite the displacement limit, the class is very competitive. It was no surprise then, that soon after Yamaha introduced its Twin Jet 100 in a street version only, some of the riders competing in this class began considering modifying Twin Jet 100s to meet their needs.
FOR THE VISITING motorcycle enthusiast, England has a great deal to offer. The TT is, of course, the major attraction, and a Sunday afternoon spent at Brands Hatch is never wasted if you like short events with wheel-to-wheel racing all the way, fought out by riders who know every inch of the course (much like American flat track specialists on their favorite ovals).
I WAS 16 WHEN I obtained my first motorcycle. It was advertised as a genuine bargain in the small ads of the local newspaper, so I rose to the bait and went to see it, though not without some misgivings on the way. The fact was that although I knew a lot about motorcycles in theory, my practical experience was very limited.
THE SPRING FRAME on the modern motorcycle is taken for granted by the majority of today’s riders. Yet of all the current engineering specifications this feature has probably taken the longest period of time to become accepted practice.
WHAT DOES ONE DO for an encore? Just take a good look at what Yamaha has done after several years of making one of the most successful trail bikes ever. The new 100 Trailmaster is not a rehash of the old one, nor is it a street machine with knobby tires, high exhaust pipe and engine guard, although it does have these things.
An Interview With One of America’s Leading Exponents of Flow Theory, Who, Among His Other Talents, Makes Sammy Run.
IF THERE IS ONE CATEGORY of individuals that the sporting press is interested in, it is winners. Granted, there is frequently a great deal of the human drama surrounding the also-rans, but these attendant tales invariably lack the punch — the hammer — that accompanies the stories of those who are outstanding in their respective fields.
BEING WELL INFORMED is considered an asset, but how well informed are you when it comes to what’s going on down below in your motorcycle’s engine? Rite Autotronics Corporation now offers a clue in a handsome, though massive, custom package.
As a service to those of our readers who may go abroad or may have a special interest in international competition, we have edited a calendar of FIM events. Not all are contested by international stars, nor are all of international significance.
THIS IS THE LATEST in the excellent series of motorcycle service books recently added to the CYCLE WORLD Books larder, and the first ever published in a serious vein on servicing the most popular series Hondas. Machines covered are primarily Honda fifties, such as the C-100, C-102, C-110 and C-114, but it also deals with the 125cc models, plus the 250cc C-72 and CB-72 Dream and Hawks.
IT WAS NO SUDDEN THING — my husband’s decision to buy a motorcycle. He’d been wanting one for ten years. But until the day when he actually went out and bought one, I was indifferent to motorcycling. When my husband would mention he’d like to have a motor, I’d respond with what I thought was expected of me: “Yes, dear, that would be nice, but aren’t they dangerous?” I associated motorcycles with Marlon Brando, first and traffic cops, second.
This picture doesn’t do the item justice after you’ve seen the real thing, which is called a “Sportscarf.” The manufacturers call it a him-or-her item. Be that as it may, the scarf has some very motorcycling-type possibilities. In bulk order, it may be obtained with club emblems (silkscreen). The material, Arnel, is very comfortable and warm without being scratchy and would go well in a rain or trials suit neck. In the middle of the 54-inch-long scarf appears an opening into which such items as lighters, keys, master links and cigarettes may be stowed. If your girlie is getting her hair blown, her head, too, may be stowed in this opening and secured firmly with an easy half granny knot. Now they are available in white only, $3.95 individually, from Sportscarf, Dept. CW, 5421 Aura Ave., Tarzana, Calif.
Motorcyclists who own machines equipped with windscreens may now obtain a vinyl all-weather cover that fits. Special cutting and design permit full coverage of windscreen, headlamp and handlebars. Produced by Belstaff of England, the covers come in two sizes, for medium-sized machines and for large bikes (500cc or over). The covers are priced at $9.30 (medium) and $10.40 (large). They are available at BMW dealers or through Butler & Smith, Inc., Dept. CW, 160 W. 83rd St., New York, N.Y.
HOT HODAKA HEAD
Hodaka Ace 90 buffs can add “instant suds” to their engines with the new highperformance cylinder head from Webco. "^The performance increase is gained through a special “hemi” type combustion chamber and use of a 3/4-inch reach spark plug for maximum heat transfer. The heads are available with combustion chambers in two different sizes: The standard head is for all engines up to and including .040 overbore. The .080 head is for engines that have been bored .050 or larger. Compression ratio is 11.75:1.
Rite Autotronics Corporation is introducing a new 110-volt, AC-DC motorcycle timing light for both 6and 12-volt systems. It features a Xenon strobe tube and a collimating lens, which provides brilliant white light even in broad daylight. Retail price is $16, and the item is available for immediate delivery from the corporation at 5221 W. Jefferson Blvd., Dept. CW, Los Angeles, Calif. 90016.
COLD WEATHER GLOVES
A new type of glove, called the Pacer, has been designed for cold weather wear. Made of Novahide, the glove is insulated with polyurethane and is thermal-lined for extra warmth. The makers say it has been tested at 27 degrees below zero and showed no cracking or peeling. The wrist area is tensioned for snug fit. Other features include ring and clip attachment hooks to hold the gloves together when not in use, and a zipper pocket on the left-hand glove to hold keys or change. Price is $5.98. Contact Wishoff Speed & Custom Sales, Dept. CW, 131 S. Orange St., Glendale, Calif., 91204. Also in the Wishoff stable is a line of gag bumper stickers with such slogans as: “Happiness Is a Low ET,” or “Powered by Credit.” They’re 59 cents each or two for a buck.
The Wiseco Piston Company, which makes pistons for motorcycles, karts and snowmobiles, is now offering pistons for the Yamaha 305, and for the 100 and 250cc Kawasakis. These are made in various configurations to increase performance, and are equipped with thin .024 rings to minimize drag. They come in standard and oversize models at $10.95 each with rings. Direct queries to Wiseco Piston Co., Dept. CW, 30201 Lakeland, Wickliffe, Ohio, 44092.
This is what all-terrain ace Jack Krizman claims for a new foam developed by his Product Testing Company. Manufactured by Filtron Products, 10549 Monogram Ave., Granada Hills, Calif., the foam is used in heavy duty air cleaner elements for dry or wet country scrambles machines. It is available for all bikes using circular air cleaner elements. The 100 percent open pore foam is so effective, Krizman says, that a Filtron which has been in use for an extended period of time will show no evidence of dirt inside even if its outer half is saturated. No gaskets are necessary to provide a seal at the edge of the filter, as the filter material itself provides positive edge sealing. The material is washable. One of the new elements was used in the machine with which motocross champion Torsten Hallman won both international classes at the Dirtdiggers Grand Prix.
Bonanza Industries has introduced a new model to its line of mini-bikes — the BC1300. Its features: 4 bhp and 4-cycle engine, jack shaft with optional sprocket changes, sealed wheel bearings, swinging rear suspension, 5-inch brakes, 40-inch wheelbase, 98-pound weight, 14.5-inch knobby tires. All the Bonanza models come with a year’s warranty. The deep foam saddles used on these machines are long enough for two people. Ride is made more comfortable by double action shock absorbers. The Model BC1300 sells for about $200 and other models range from $110. For further information, write Bonanza Industries, 24-26 Barnard Ave., San Jose, Calif., 95112. Bona fide dealers may call the company collect.
A line of bumper carriers has been introduced by the Sammy Tanner Distributing Co., 615 N. Avalon Blvd., Wilmington, Calif. Finished in dull black, they may be attached to the rear bumpers of most American cars quickly and without the use of special tools. The angle of the carrier is adjustable and the parts coming into high-pressure contact with the bumper are rubber-lined.
SAFETY BAR FOR BMW
The Montesa line for 1967 is essentially the same as last year’s, with detail improvements. It consists of three different machines in the popular 250cc size: the La Cross scrambler, the Scorpion street scrambler, and the Impala Sport road bike.
IF OSCARS WERE PRESENTED for motorcycle movies, surely “Three Wheels at Mallory” would have been the winner for 1965. Unfortunately, it takes a year for new Castrol films to reach these shores, but it has been worth the wait. The curtain raiser features an animated pop art title of sidecar racers backgrounded by harmonica music.
BLAZING FROM THE HEADLINES comes the story to end all stories — a fairy tale that would do justice to Hans Christian Andersen. The most improbable challenge of all, car vs. bike round the Isle of Man TT course as a highlight of the 1967 Jubilee races.
A SMALL GROUP of Italian enthusiasts, headed by a German technician, has created a new road racer for the privat wishing to contest the one-two-five GP class. Called the DRS, it was successfully tested both at Monza and Modena by rider Angelo Bergamonti and will be produced in a small batch for sale at about $1,600.
MOTORCYCLE FIRE TRUCKS. That’s the latest exotic use to which motorcycles have been put in Japan. First tried over a year ago in an outlying area, now the fire department in Japan's second largest city has gone in for motorcycles to replace fire trucks in a big way.
