“To add speed, add lightness.”
This saying is often attributed to Colin Chapman, founder of Lotus Cars and racing Team Lotus. In essence, it is the passionate pursuit of speed and performance through economy of materials, creative design and ingenuity. Adding lightness is a captivating paradox, the seemingly contradictory ability to add something by taking away. What drives you?
In the beginning… When I first got the Aprilia, starting the bike with a cold engine would go something like this: Kickstand up. Ignition key on. Shift gearbox to neutral. Kill switch set to Run.

Gently rev engine for a minute or so while stationary. Put on helmet and gloves. Set off down the road gently, upshifting before 7,000 rpm, keeping an eye on […]
One of the main benefits to ITBs is their very small throttled volume (that is the volume between the throttle plate and the back of the intake valves), which bestows them with excellent throttle response. Another benefit is that that they have a very large throttle area, which means they can flow a lot more air, without the negative consequences of a single throttle of similar area. You see, throttles must be sized appropriately for the engine. Like the fairy tale of Goldilocks and The Three Bears, you don’t want a throttle that is too big nor too small. Throttles […]
Well that was quick! My new MS Labs CAN Wideband Module with optional OBD-II port has arrived. UPS 3 Day Select all the way across the country arrived in just 2 days! Big thanks to Trackspeed Engineering for the quick order processing. Some observations: The new hardware enclosure is anodized black instead of silver/clear. The case screws are now T10 Torx instead of Phillips head. There is a second serial connector for the OBD-II harness. The PCB is v2.1. Obviously a completely different design to accommodate the OBD-II. No more jumper wires on the back side of the PCB. Sorry […]
