Replaced the Crankshaft Position Sensor in my '15 Bonnie.
Had just ridden 120 miles through forest and mountains up to the snow line, came back as it was getting dark with the temp dropping fast. Luckily, the bike ran great all the way home.
First thing the next morning...no-start!
Tried many things to determine the problem, finally paid the dealer to diagnose.
They said their code reader was propriatary, but have since seen a guy on the internet using an OBD-2!
One month later my part arrived. Pretty easy install, just gap the sensor 0.8 mm and route the harness. No problem!
The story I was told is that the old CPS's had a tendancy to go out like that without warning. Mine was at 13,000 miles. The service writer said his popped at 5,000! Supposedly the replacements are improved and are much more reliable, I hope so!
Thai Bonnie now fires right up and runs great again!
