My bike was stuttering randomly and stuttering over bumps. It felt like the FI system shut off for a split second and restarted. When it did the FI light on the dash would come on, the bike seemed to run fine with the light flashing, pulling in the clutch, flicking the kill switch off and on would stop the FI light flashing.
I pulled up the code and it was for the fuel injectors. On a hunch I removed the Power Commander that has a custom map. Now the bike ran much worse, it would stutter, the motor would shut down and restart four or five times with in the space of a few seconds immediately after a roll on up shift from second to third. Although, after removal of the Power Commander the FI light no longer was flashing.
On another hunch I removed the Timing retard Eliminator, this improved things somewhat. The bike no longer stuttered repeatedly but still cuts out over large bumps although not as dramatically as before.
So I decided to trace the harness looking for any damage.
I had no success finding a crimped, bare, corroded, etc etc wire. Then, with a beer induced clumsiness I was rearranging the tool kit in the tail compartment and the tip on a sliding T handle socket wench handle was resting on one of the little black boxes that control the alarm system motion sensors. The wrench slipped from my fingers, dropped no more than a couple of centimeters, tapped the box and the motor shut off. After repeating this neat trick several times moving the wrench to the other side off the tail compartment and securing the box with a zip tie on it's admittedly loose velcro moorings cured the problem completely.
Smooth or rough roads, now it runs like a raped ape . I'm a happy man.
