Random newer-bike-stuff I had not considered until I had one: OBD2. I did not expect an OBD-compliant ECU. The cable format is different but nothing that $13 at Amazon won't fix. A scan tool specific to the ECU,
Scan M5X, was on the Google play store. Setting it up with my Bluetooth OBD2 dongle took some fiddling but I got it eventually.
It had some pending codes (a cam sensor, O2 heaters) that I cleared. Hoping they were just artifacts of an earlier dead battery. I also reset the service reminder so it would stop bugging me every time I turn the bike on.
The "race mufflers" on the bike were just completely gutted stockers. You could see right through them. I got some 500 mile take-offs for $150 delivered! The catalytic converters keep my ass warm and actual mufflers keep everyone else happy.
I was supposed to look at a non-running '13 848 Corse SE yesterday (same bike w/an aluminum tank, quickshift, traction control, bigger front brakes, and Ohlin$ shock) yesterday but the seller flaked. Maybe today. He claims the engine is good, it's just an electrical problem. Uh huh. Wife: "so, this is going to be like the bicycles?" "Ummmm..."
