Bought a combined rotor/engine speed sensor from Dough Schochard specifically tailered to the Helicycle. It also came with a new pick-up and magnet ring. I have to make a bracket to mount the sensor undr he hood bracket. I used some 6061 aluminum angle material to make the bracket. Started with a paper template. I used to 2 top bolds for the slider backet to also hold the sensor bracket. I machined slightly elongated holes into the top of he bracket. This will allow me to mode the sensor slightly to adjust for the proper air gap between sensor and magnet ring.
