On Friday Nov. 26, 1982 my youngest son went to the post office. He filled out a form, signed it and gave it to the clerk. He was registered for the draft. I still have three sons and a daughter. Because the youngest is in school and hits me up for lunch and gas money, I still have a dependent.
Letters to the editor are welcomed and should be addressed to: Cycle World Fditor, 1499 Monrovia Ave., Newport Beach, Calif. 92663. All letters are subject to editing and cannot be returned. Up Front in the December issue of Cycle World captured the dilemma of Jay Springsteen better than anything I’ve ever read.
Wait, now. This may look like just another English book about another English motorcycle no longer with us, but don’t quit yet. First, this book is about the Vincent, the stuff of legends and (unlike some deceased brands) the legends had some basis in fact.

End of squeal, according to CRC Chemicals. Disc Brake Quiet is available from motorcycle and auto parts stores.
And calls, too, about a recent Sunday Ride piece we published. It’s rather surprising, in a way. Those Sunday Ride pieces, you’ve more than likely noticed, are short features about the favorite short, fun day-long jaunts of riders in different parts of the country.
Racing improves the breed, everyone knows, but most of the people building street bikes long ago quit racing the motorcycles they sell the public. After all, who needs a bike like Kenny Roberts or Freddie Spencer? There is, however, one racing motorcycle that could be—make that should be—a street bike.
More Speeds,Better Manners, and Improved Suspension
If we were to give an award for the most changed '83 motocrosser, Honda's CR480R would be the easy winner. Playing a guessing game of “what's different,” one quickly finds everything is different. From the chassis to the hubs to the engine.
Sporting Simplicity, For Those to Whom Too Much Is More Than Enough
There is a case to be made for simplicity. Consider, for example, the Suzuki GS450. It is a vertical Twin, dohc with two valves per cylinder and plain bearing crankshaft. Since the GS450 was introduced three model years ago, Suzuki has brought into production two other similiarly-sized machines, an eight-valve Twin and a 16-valve Four.
It's the Colorado 500, and It's What Car Racers Do In Their Spare Time.
Explaining the Colorado 500 without name dropping, would be like entering a motocross without a motorcycle. It would go something like this: For the seventh year in a row 103 motorcyclists of varying ability gathered in the mountains of central Colorado to ride approximately 500 mi.
How To Make A Used Yamaha 650 As Fast (And As Expensive) As A 750.
Motorcycle technology is a two-sided coin. Better and faster and quicker motorcycles are good; having a perfectly-good motorcycle made obsolete by a new, better, faster and quicker machine is not so good. The Seca 650 is a case in point.
When working on motorcycles, it seems, nothing is as easy as it should be. Modifying a motorcycle compounds the problems. In modifying the Seca 650, we had our share. In no particular order, highlights follow: —Information. The local Yamaha shop didn’t have a Seca service manual in stock, but ordered one for us.
Lots of Use, More Than Enough Abuse and a Record For Miles Per Year Left the Big Red Rocket Tired but Unbroken.
Remember before you went riding in the dirt? The old hands spoke only of get-offs and mechanical failure, of loops and highsides and running into trees and getting stuck in swamps and killer downhills and bruises and sprains. Because you hadn’t been there, the whole thing sounded like second prize in a firing squad raffle.
An Alternative to Telescoping Forks Could Be Lighter, Stronger and Better. But Does Anybody Want It?
Quick, think of a motorcycle. Any motorcycle: Size or type doesn’t matter. Have it pictured in your mind? Focus on the front end. We’ll bet the front wheel is held to the frame by a set of shiny telescopic forks. Telescopic forks are so universal these days it’d be surprising if your motorcycle image didn’t use a set.
It’s funny, in a way. Let’s say it’s, oh, 1973. A nice, clear Sunday afternoon, one of those magical days that falls somewhere ’twixt winter and spring. You’re out for the first real warm-weather outing of the year, parked beside a roadside cafe, sipping coffee from a styrofoam cup as you stare up the pavement that skitters away through the trees.
You do save old issues, don’t you? Good. Root around in the closet or the garage and see if you’ve still got Cycle World for February, 1982. Turn to page 33, the Harley-Davidson ad with the picture of the crate. On the next page there’s a photo of an FXRS. The headline says “Maybe this time nothing will get lost in the translation” and half the text is in Japanese.
Offset Crankpins Allow Honda's 45 V-Twin To Have Perfect Primary Balance, But Not Perfect Smoothness.
Engine smoothness is at the very heart of the Shadow’s engine design. To get an idea of the forces involved, imagine the piston from a normal 350cc Single. Fling it downwards in the bore at over 70mph and at the bottom of the bore yank it to an absolute stop.
Just in time, the Motorcycle Industry Council saved us from shame and disgrace. Late in 1981 we borrowed two Husqvarnas, a WR430 and a WR250, to test for a year. The 430 went to our demon offroader, a retired racer who rides every weekend, dawn to dark.
Would You Believe a 750 Single? How About a TWo-Liter Twin?
C. D. Bohon
Not long ago, I heard a rumor that a Japanese maker was experimenting with a 750cc Single, not with an eye for immediate production, but as a sort of project vehicle. Horsepower was supposed to be around 70, which is reasonably respectable for a 750cc Four.
Nearly everyone has read about Maico's legendary cornering expertise; even a klutz can corner fast riding a Maico, any Maico. Anyone who had ridden a Maico knows the legend, like most legends, is somewhat exag gerated. Still, it's hard to forget your first ride on a Maico.
Black and white photography doesn’t do this jacket justice. In real life it’s a brilliant, flaming, dayglow yellow-green, the color used for fire trucks and life rafts and for the same reason: it can be seen from miles away and thus, one theory goes, the color makes the rider safer.

Riding Ray Worth’s Yamaha Seca 750, Joe Yeager, 32, of Belton, Missouri entered six NMRA Super Modified races and won five, setting new E.T. and mph records at four events. The single race Yeager didn’t win was rained out. The Super Modified class is virtually identical to Pro Stock but has a 760cc displacement limit.
One carburetor per cylinder has become as normal on motorcycles as two shocks on the back of every bike used to be. Times, we are told, are changing. Enter Dale Walker and HP (Holeshot Performance) Products. Besides a successful career as a motorcycle drag racer, Walker has a motorcycle repair shop.

Any Harley rider is familiar with the tingly finger, numb hand sensation that comes with a long ride. No feeling, except pins-and-needles. Handlebar fatigue, you could call it. Stock grips, made of hard rubber, just don’t isolate the vibration enough.
