“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?

CB350 Fuel System Plumbing

I’m using a Pingel Power-Flo On-Off “Race” fuel valve with a 5/16″ outlet. My Mikuni VM30 carbs are designed for a 5.5mm ID fuel supply hose. Given the size mismatch I needed to find a way to step down the hose size from fuel tank outlet to carb inlet.

From quick disconnect to Pingel 1-in 2-out fuel filter. Conveniently, the fuel filter is 1″ in diameter so I use a stainless steel […]

Dashboard Pipe Holder

I stumbled across this charming 1925 Morris Oxford Long Wheelbase “Bullnose” Tourer auctioned by H and H at the Chateau Impney sale in Droitwich Spa, Worcestershire, England back in 2014. In the auction catalog I spotted this picture showing the most charming dashboard pipe holder and ash tray.

Tuning Tasks

Check original base tune setting for CLT thermistor setting. I messed around with this when my CLT sensor was stuck at the failsafe value of 180F. Turns out I had a broken wire in a butt splice underneath some heat shrink that I repaired. So which is it, Mazda or RX-7 S4&S5? Figure out why MS3 is not reading NB cam sensor. Could be bad sensor or bad wiring between sensor and CAS harness. According to Reverant, the MS Labs MS3 needs no adjustment to fix this. Maybe it has a circuit that automatically adjusts sensor input sensitivity or gain? Regardless, I’m unsure whether there is a […]
