BAS turn-offs were getting significantly worse (as much as every 10 secs for several minutes). Dealer didn't have the recall kit in stock and wouldn't for a week. Can't wait!
Removed and disassembled BAS. All you need is a small pocket screwdriver or o-ring pick to unlock the 3 latches holding the sensor together then pull it apart. Everything is self-indexing; you can't put it together wrong. Found the axles on the pendulum badly worn, allowing pendulum to bounce around uncontrollably from vibes. Wiped all the dust residue from the worn axles off the circuit board and inner housing. Oriented the pendulum on the board (see "UP" mark on housing and figure out where it has to hang- the dark insert at the bottom of the pendulum is a magnet- it has to hang over the small square device soldered to the board) and applied a few dabs of silicone rubber to keep everything in place.
Test started it then let it sit overnight to allow silicone to cure. Rode it 70 miles today- no failures.
This is a handy skill to have because 1) it could easily be done on the road, and 2) my understanding of the recall is that the sensor is the same design, just in a different location. I don't know if the tail section vibrates less than the ECM mount, but I wouldn't be surprised if some of the bikes with recalls done started having issues.
Keep in mind that this is a band-aid and the BAS won't work to protect the engine in case of a tip-over, but it'll get you home.
Sorry I didn't think to take any pix, but it really is an easy fix.

The recall just moves the BAS, heat and vibration were the cause to the failures. Some people have had failures after the recall, usually because it was damaged before the recall was performed. A few oddballs like Ft_bstrd have had a few new ones fail even after the recall.

As for the fix, 2 minutes and ECMspy, turn it off. It is fully reversible too.

Sure, if you carry your laptop to Siberia, or wherever you are when it fails.

This is 2008, I have it on me if I am going more than 100 miles from home. : )






Cant really see it, hidden behind the bags. That was on the Dragon last Sunday. The bike's AFV got messed up, so it was running poorly. Whipped out the laptop, did a few quick tweaks, reset the AFV to 100, and did another run, better than new : )
