Joe
Smith and Son racing team pose proudly with the world's quickest
drag bike. Joe does the riding, Gene helps his dad with much of
the work between rounds. Maintaining a fuel bike while racing
on tour becomes a full time familyproject, but end result is new
world E.T. record! |

| THE
NINE SECOND barrier is history! Joe Smith of West Covina, Califomia,
opened a new era of motorcycle drag racing at Bakers- field this
year with a stunning 8.97-167.28 to be- come the first man in history
to ride a motorcycle through the quarter-mile in less than nine
seconds. The heart of Joe's machine is a late model Har- ley shovelhead
displacing 108 cubic inches with S&S flywheels and Burkhardt
barrels. Joe did the head and valve modifications of his motor and
chose a Leinweber cam to complete the valve train. |

The
heart of Joe's machine is a late model Har- ley shovelhead displacing
108 cubic inches with S&S flywheels and Burkhardt barrels. Joe
did the head and valve modifications of his motor and chose a Leinweber
cam to complete the valve train. An S&S carb meters the nitro
to Venolia forged pistons, spark is by a Joe Hunt magneto and Gary
Hooker fabricated the chromed headers. The lower end is built and
maintained by Bill Cobb, the shop foreman at Laidlaws Harley-Davidson,
where Joe works as parts manager. |
| Joe
says that Bob Laidlaws' enthusiastic sponsorship is responsible
for much of the bike's good fortune at the races. The separate transmission
has been reduced to a high gear only unit. Diamond chain transfers
the horsepower to the rear wheel. Paul Burkhardt built the right
side cover. Smith designed and built the fueler frame of chrome-moly
tubing, making 70-inch wheelbase including the Ceriani forks. The
front wheel is a light alloy rim laced to a Harley Rapido brake
and mounts a shaved and trued 2.75 x 19 Avon tire. A wheel shroud
is installed to give Joe every last bit of advantage at the starting
line without red-lighting. Lead weighs bolted to the forks reduce
the possibility of wheelstands. |

Short
drag bars carry the controls and kill button, while fork brace and
a steering damper help to eliminate any undesirable handling problems
at speed. Fuel is carried in twin tanks strapped to the upper frame
rail with large Neoprene lines to route the mixture to the S&S
carb. The rocker covers have been opened up to provide access for
hand oiling; there are no oil lines to the heads from the cases.
The rear wheel assembly is a Triumph unit mounting an M&H slick,
size 4.00 x 18. The rear brake is actuated by a simple foot lever
attached to the hub. Engine and rear wheel sprockets are changed
as needed to match strip conditions. |
