Avery's Diesel Motorcycle
Details
concerning Avery's Motorcycle
It's based on the Daihatsu D950 3 cylinder industrial
engine. A BMW 5-speed gearbox and shaft drive are being used. Notice
I have retained the engine driven fan (it increases the *gawk* factor!).
The radiator is from a Kawasaki 1500cc cruiser. When this picture was
taken, the downtubes had just been welded onto the steering head. The
right rear section of the frame aft of the bellhousing is a rough prototype
constructed from exhaust tubing. I use the Eyeball Design principle,
so there is a lot of trial assembly that you see here to determine what
*looks right*. Please note the picture has been touched up slightly
to remove the jackstands from beneath the rear of the frame and the
blocks holding up the rear fender! Early Harley Sportster fenders will
be used, not the BMW fenders shown here. Wheelbase is a reasonable 61.5
inches.
1) The exhaust system is a 1-into-2 system ending in
Harley Sportster mufflers. The flex tubing used for the exhaust headers
was for development
and display purposes only. Intake and exhaust manifolds have yet to
be fabricated.
2) The seat and tank shown are constructed of foam for
development and display purposes. The final versions of both will be
slightly different than shown
e.g. larger tank (est. 400 mile range).
3) The bike is being constructed as a mild cruiser;
it has a feet forward riding position a la Harley but retains the 27
degree rake of the BMW fork.
4) BMW drive train coupled to a 26.8 hp Daihatsu D950
industrial engine. The engine governor will be left undisturbed, permitting
a top speed of about 60
miles per hour at 3600 RPM. If the bike performs as expected, I hope
to obtain 1.35:1 gears for the gearbox from Wolfgang Kayser in Germany
which
will result in a maximum speed of 70 mph. Dave Hubbard and Sam Mayberry
in the USA (Daihatsu powered BMWs) suggest the engine can handle the
taller ratio.
5) Radiator is NOS for a Kawasaki Mean Streak. By using
the original belt drive cooling fan instead of an electric fan, I was
able to keep the wheel
base to 61.75 in.

details.
The
Fuel tank has been intentionally designed with no curved sections. It
will be fitted with a teardrop styled composite cover. This allows the
shape of the tank to be changed simply by fabricating a new cover. The
tank has three Colder quick disconnects to allow removal without any
air getting into the lines. The exhaust headers will be fitted with
heat shields. A 6 inch sample is fitted in front of the left muffler.
The round thingie under the nose of the seat is the signal generator
for the electronic speedo.Temporary seat is a repro for pre 1970 BMWs.
A custom solo bench seat is planned.
The Motorcycle is very narrow, the widest point below the handlebars
is 18 inches at the alternator. Radiator will be fitted with a fascia,
a shroud will cover the alternator.Harley Sportster air cleaner cover
isn't. It is a non-Harley part used to cover the fuel injection pump.
The air filter is located behind the engine. The only HD parts on the
notorcycle are the mufflers which are very rarely seen on a Harley.
These ones were used for less than one mile, I paid $60 for the pair.
British repro tail light. BMW. The headlight, signal lights, controls,
cables, mirrors, and wiring harness are BMW.
Sanders
Diesel Daihatsu Project
Finally,
after 8 years in the making, Sanders Daihatsu powered Chopper is completed
and running. It made a show at the 2006 Rally In Hamm and after some
old Diesel had been cleared from its pipes it was fired up and ridden
about the place. The Frame and gearbox were homemade. The gearbox is
some piece of work, it having been designed with CAD software.
Daihatsu
Guzzi
This
machine, formerly of the Carabineri made it's first showing at the Rally
in 2004. Not sure what gearbox is used.
