Engine: 3000cc V-twin (yes that is a three with three zeros then the cc)
Valves: Rotary Valves ÔÇô Chain Driven
Ignition: Dual Pug Ignition
Fuel System: Fuel Injection
Frame: Backbone Frame
The frame also carries the fuel for the bike.
Suspension: Rigid Front and Rear Suspension
Bakes: Drop the ÔÇÿsÔÇÖ. There is one front ventilated drum brake.
Clutch: Multi-plate dry clutch
Transmission: Transmission? Transmission! We donÔÇÖt need no stinking transion.
Final Drive: Dual Chains
The connecting rods are like a body builderÔÇÖs arms with pistons the size of coffee cans at the ends.
They are then topped off with rotary valve heads.
The rotary valve system is a fascinating concept. I did not come across any information as to why he chose to use them. It may be a design experiment or simple way to avoid some of the complexities of the traditional valved head.
The heads feature rear facing exhaust and forward facing injector bodies.
Once the fuel air mixture is sucked into the motor by those coffee can pistons it is fired by a duel plug ignition system.
The power generated is delivered through a multi-plate clutch to a bevel gear that drives twin chains used to turn the rear wheel.
When Walker designed the brake system it is obvious he did not take NewtonÔÇÖs third law of motion into account. The Australian builder may be counting on having a continent to cost to a stop on because he only put a single ventilated drum brake on the front end of this monster to bring it to a halt.
Fortunately it was strong enough to bring Big Ned to a halt at JuanÔÇÖs Caf?® del Fuego so it could be displayed in the WorldÔÇÖs Smallest Motorcycle Museum.
