I RECENTLY MENTIONED the Revell Motorcycle Model contest, which the Revell people tell me is now ready to roll. As a reminder, the contest is for motorcycle models submitted before January 31, 1972. It is open to anyone in the U.S. building any l/8th scale model from an existing kit.
Re:Change to New York General Obligation Law No. 9-103, Article 9, allowing recreational use of motorized vehicles on private lands, without the land-owner being libel for personal injury. New York’s “Forever Wild” conservation laws bar motorcycles from state park and forest lands.
Recently I purchased a 1971 Honda CB450 K4 from my local dealer. After approximately 500 miles, the front brake (hydraulic disc) began to squeak, at which time I asked the dealer about the problem. He said, “Wait until 1000 miles when your first service is due and we will take care of it then."
Having ingested a considerable quantity of cycle road test data during the past few years, a group of my friends and I decided to conduct a test of our own over the 1970 season, wherein each of us would use a different motorcycle, do the majority of our riding together under loosely controlled conditions, and freely exchange information and opinions as the year progressed.
How To Build And Interpret Readings From A Carburetor Balancing Device (Using The Honda Four As An Example).
BUILDING YOUR MULTI-BALANCER
HOW TO USE YOUR MULTI-BALANCER
WITH THE INTRODUCTION of the mighty multi-cylindered engines on today's motorcycles, the problem of carburetor synchronization and manifold balancing becomes acute. It is especially noticeable on Honda's big Four, where a slight maladjustment can cause a great deal of lost horsepower.
Meet The Desmo-Rooter: A Set-It-Up-The-Way-You-Like-It Charger.
IS THERE ANYBODY out there who appreciates the virtues of a 500 class four-stroke Single any more? (Echo.) Hmmm, not many left, maybe. Too bad people have to be so damn serious about specialized dirt machinery, light weight and all that stuff.
THE THIEF WHO BROKE into a motorcycle salesroom in Manhattan, Kansas, and cut out on one of the bikes, was soon caught by the police. His excuse has become a classic: "I guess I'm a cyclepath," he said. The unintended pun caused smiles, but the business of motorcycle theft stopped being funny a long time ago.
YOU'LL FIND IT hard to beat the professional thief, but you can stop the amateur dead in his tracks. Luckily, most heists are pulled off by joy-riders, or someone who wants a new set of tires. Here's how you can beat them. If you stop and think about the act of stealing, you quickly realize that there are three circumstances a thief tries to avoid.
THE MACH III is a heavy act to follow, having established its reputation as a giant-killer. So readers will undoubtedly be disappointed that the Kawasaki’s new three-cylinder marvel, the 350 S2, is only one of the fastest 350s we’ve tested rather than the fastest.
FOR ROAD RIDER AND DIRT RIDER. A SPECIAL SUPPLEMENT.
The motorcycle trek down the Baja California peninsula is to the motorcyclist what Everest is to a mountain climber. But few stories have captured the flavor of this fabulous dirt ride from the California border to La Paz. So we assigned freelancer Bob Sanford the task of assembling an exploration party to bring back the “real” Baja.
IS BAJA FOR HERO/RUGGED INDIVIDUALIST TYPES ONLY? SHOULD YOU RIDE SOUTH EXPECTING BLOOD AND GUTS ADVENTURE? IF NOT, WILL YOU SETTLE FOR PARADISE?

One Lousy Flat tire. Can you believe that? Eight motorcycles tackle 1000 miles of what everyone describes “bike and body breaker” and all we’ve got to show for our efforts is one lousy flat tire. Incredible, isn’t it? Everyone knows that you’re supposed to bust hubs, seize pistons, break cables and run out of tire patching equipment when you ride the Baja.
A well prepared machine and a carefully considered assortment of parts, tools and supplies are vital ingredients in determining the success of long distance, off-road trips, such as the Baja. Without these, chances are you’ll spend the rest of your born days sipping cerveza in a little Mexican farm town (which is not such a bad idea).
There was a wide variety of machinery on our excursion to Baja. From two-stroke street scramblers, to whining, full-bore racers, to four-stroke street bikes. We were curious to see how various types of machines would fare. Most of the bikes were new or almost new, but a few, particularly the competition machines, would never again see adolescence.
La Paz? Sure...Why not?” Bob and I have always gotten along tolerably well, and two weeks in Mexico sounds bound to chase away the blues. I’m an “ace” bike rider with nearly seven years in and on L.A. streets and freeways, so, I figured no sweat there.
If you’re going to Mexico, get a tourist card. These are available, gratis, upon proof of citizenship (birth certificate, draft card, etc.) through the Mexican Government Department of Tourism, located in several major U.S. cities, including the Los Angeles offices at 3106 Wilshire Blvd.
There is a surprising amount of reference material on Baja California, if you know where to look. It has proliferated along with the dune buggy/4WD invasion of the peninsula, so it is not surprising that some of it is oriented towards four-wheeled vehicles.

THE SUBLIMINAL BLEEPING of the alarm dissipated the last, lingering wisps of a dream as Jon stirred to consciousness. Mechanically, more by force of habit than by direct effort, he threw back the slider to his sleeping chamber and then grimaced as he planted his feet on the cold floor of the room.

FIM, ISDT, Olympics...if you’ve listened to Russ March lately, you’ve heard all of these mentioned in connection with the “new” AMA. One of Russ' stated objectives this year is a United States team at the International Six Days Trial, to be held this fall on the Isle of Man.
PRELIMINARY FINDINGS ON MOTORCYCLE CRASH RESEARCH—AND SOME SHOCKING HELMET FAILURES
FAIL AND BAIL
GRAVE HELMET FAULTS

IVAN J. WAGAR
WILL your next motorcycle be a chopper? It could be, if the legislator pays much attention to the conclusions of a series of motorcycle crashes conducted by a UCLA research team. The group slammed seven Hondas, ranging from a CL90 to a CB750, at speeds of 20, 30 and 40 mph, into the sides of late model cars in their efforts to determine what happens in motorcycle/car conflicts.
RATHER THAN DESIGN an all new frame and running gear for their prototype micro trialer, the Rickman brothers opted to use as many components from their Micro Metisse motocrosser as possible. The end result of this parts merger is not a competition ready trials mount, but it does show enormous potential nevertheless.
IT WAS MALCOLM SMITH who first climbed aboard the pair of Husqvarnas that importer Edison Dye initially brought here from Sweden in 1966. Looking at the seemingly frail equipment, Smith declared that they were obviously “pieces of junk.” And then he rode one and reckoned that they were so fast they would “never hold together” during the rigors of tortuous desert racing.
A Trail Bike For Those Who Have Everything & Would Like To Do It The Hard Way For A Change.
AS A DIRT BIKE, the Broncco Apache l00 may be considered a downright indestructible street bike. It falls short of its intended use as a dual purpose trail bike, which is unfortunate, as it has some nice features. The Apache is an Italian import, and that explains its eccentric, cobby styling.
BRITISH MOTORCYCLE manufacturers have been noted for their traditional conservatism—producing a basic design for many years with only minor annual improvements. The Italians, on the other hand, have a reputation for being creative, with all sorts of new and unusual roadsters and racers flowing off their production lines.
After the two unlucky opening rounds of the 500cc world championship, which did not net reigning champion Bengt Aberg any points at all, Husqvarna had some hopes for a better outcome on their home ground. Aberg was second fastest in practice, after Friedrichs (CZ), but also fell and injured his wrist.

CUSHIONED REAR SPROCKET
A cushioned rear drive sprocket has been designed for the Hodaka 100 and Super Rat to counteract the effects of high stress applications, where both the engine and rear hub are subjected to severe shocks. Based upon extensive testing in actual desert riding and motocross situations, the cushioned hub assembly is claimed to reduce stresses on the gearbox and drive train. The hub assembly mounts in place of the standard rear sprocket, and utilizes six rubber inserts to absorb shock. The hub is available with sprocket sizes ranging from 48 to 60 teeth. The part number is 1248. Retail price is $29.95. For further information, write to Webco Inc., Dept. CW-9, 2l8 Main St., Venice, CA 90293.

In the interests of Less Sound, More Ground, J&R Mfg. has combined their silencer and the Krizman spark arrester into one compact unit. For power without noise, the small, light unit can easily be adapted to any motorcycle. It measures 11⅛ in. long, 2 in. in diameter, and weighs 20 oz. The silencer is made to fit any size exhaust outlet to close tolerance, and two hose clamps are all that is needed to attach the unit. The straight-through design of the silencer results in no power loss; in fact, certain dyno tests have shown a marked increase in mid-range power. The spark arrester is fully approved for forest use. For further information, write J&R Mfg., Dept. CW-9, 6001 N. Maywood Ave., Huntington Park, CA 90255.

MINIATURE SWEPT BACK BARS
Miniature swept back bars for Yamaha Mini Enduros are designed for all riders to give better feel and control in off-road riding. Big riders will find the design of these swept backs an advantage-the higher rise will clear larger riders’ knees in tight turns. The bars measure 28⅛ in., end to end, and come in black oxide. Retail price is $9.95. Order directly from K&N Engineering, Dept. CW-9, P.O. Box 1329, Riverside, CA 92502.
It has been generally believed and lamented that Honda is merciless when it comes to preserving its historic models and racing wares. Five years ago I wrote a story on the first Honda Four, circa 1959. It was built to race and win just once in a local meeting, and then quietly disappeared into oblivion.
Because of a postal strike at the time that entries should have been flooding in to Edinburgh for the 1971 Scottish Six Days Trial, entries were increased from 200 to 240. The decision immediately brought criticism that the larger number of entrants would make the trial unmanageable.
Giacomo Agostini’s home town, Lovere, was again chosen as headquarters for the famous “Valli Bergamasche,” a tough European ISDT-type trial. This year, the 23rd edition counted as the fourth round of the FIM championship. Because of traffic congestion and noise, it is no longer possible to begin this event from its classical center of Bergamo, but organizers have found an excellent substitute at Lovere.
