I am working on upgrading the fuel injection system on my BMW K75.
For some details, see here: http://en.wikipedia.org/wiki/BMW_K75
TLDR: 3 cylinder, 750 cc, 2 valve per cylinder, motorcycle engine.
Currently, the bike uses an analog LE-Jetronic fuel injection system, with an antiquated flapper MAF sensor, and nothing else. This results in mediocre fuel mileage at high rpm, as the computer enriches the fuel mixture for safety, as the computer can't correct with an oxygen sensor.
I plan to add a more modern, digital system, with a wideband O2 sensor. VEMS fits this job perfectly.
