Mr. Max Snow, who made his first appearance at Kilburn Speedway,
Melbourne, last month, riding his new special 8/80 J.A.P., has built up an interesting
machine which should place him well in the running in the sidecar events once he has
overcome the teething troub1es that are always present in every new motor that is used for
An 8/80 J.A.P. motor is the ambition of most sidecar riders but as there are only about
four of these motors in this country, and they nearly all grace speed cars, the position
is fairly hopeless.
Max started building up the motor some months ago, and as he could not secure a
complete motor, he decided to build up a hybrid, employing the 8/80 parts that he
The crankcase was from a Daytona Indian, complete with flywheels to which was fitted
dirt track J.A.P. barrels and heads with two twin float, racing Amal carburettors.
However, on a try out after all the work was completed, the timing gears gave way,
smashing the crankcase. As the crankcase was beyond repair, Max scouted round and managed
to secure a J.A.P. crankcase which was fairly complete. To this crankcase has now been
fitted, after a good deal of work, the original barrels and heads. The barrels employed
are the short type and to accommodate the longer stroke, large spacers had to be fitted
between the base of each barrel and the crankcase. The magneto drive on the crankcase will
accommodate two magnetos, one for each cylinder, which is the usual 8/80 practice, but as
the magnetos were missing a single magneto now supplies both cylinders.
The motor is mounted in a modified Brough Superior frame with Harley (castle forks),
the power is transmitted to the rear wheel by means of a Harley gearbox.
