icture this: An air cooled 1000cc motor screaming it’s heads off at 2000 RPM past its stock red line in the heat of a parched salt lake in the middle of a desert. And how about the head in the helmet? Need to avoid heat stroke in any of these three heads! I’m using a […]
ere’s a quick rundown of the process I went through in sorting the rear suspension geometry of the salt racer. First task was to calculate the shock specifications. I started manually calculating these with the help of a couple texts including Tony Foale’s tome on the subject: Motorcycling Handling and Chassis Design. Even though the […]
he frankenswingarm is finally looking like it should. Freshly powdercoated K100 17″ wheel; powdercoated R1100 RT swingarm; R1100S bevel drive; aftermarket carbon hugger for R1100S; Custom made adjustable torque arm. All grafted to the arse of an unsuspecting airhead.
ere’s a method that involves little math compared with the conventional method as described here The following method involves bolting the head and cylinder together as an assembly on the bench using all-thread. Then carefully placing the piston in the cylinder at exactly where it would be if it were at top dead center (TDC) […]
n adapter flange is needed between the output flange of the airhead gearbox and the drive shaft of the oilhead swing arm. The adapter has a round spigot that is press fit into the female spline of the uni-joint on the R1100 drive shaft. Then the adapter will be welded to the uni-joint. The adapter […]
I got a couple heads from a 1989 R100GS for the salt racer. These are the ones to have since they have the so-called ‘D ports’ and have larger intake spigots since they take 40mm Bings. Got them cheap because one of them was busted up: 4 broken fins, a cracked 6mm hole that takes […]
The dyno is almost complete. The Datamite 111 dyno system by Performance Trends is hooked up and loaded into the laptop and I have taken the first trial runs. All that remains is to calibrate the dyno and hook up the brake caliper. Oh, and the small matter of building a room around it!
