Log Off

Friday marked the arrival of the long awaited datalogger for the bike.
Yesterday was spent fitting it and  making up a mounting bracket, plus fitting the countershaft collar & magnets. Unfortunately it's arrived incomplete, as the hall/driveshaft speed sensor is missing from the package. I've been in contact with the supplier who are going to get back to me.
The mounting bracket was an excuse to actually use the mill, which has been sat almost totally unused since getting it over 6 months ago. The logger is bigger than i imagined (but feels like a very empty box) but the place i had in mind for it which is under the seat, is still big enough - just!. The logger has to be mounted flat and facing the right direction for the internal g-force sensors  to work properly, so you are limited to mounting locations.
The basic unit and included sensors will record:

• Battery Voltage
• Engine RPM
• Countershaft/driveshaft RPM (which is also relative to rear wheel speed)
• 2 axis G-meter (acceleration)
• a 12v event (i'll connect it to the wide open throttle switch for now

Each channel (Maximum is 21) is capable of recording at 100 samples per second (Hz)

The clutch lever has been removed recently too, in it's place will be a rear brake lever (which is actually a hydraulic clutch lever), picked up off ebay. It'll need a very long brake line to connect it up but it will be worth the conversion as the back brake is awkward to use as it is.
