It's near 60 deg. here today so I took the Fat Bob out for a little spin. I was only a couple of miles into my ride, cruising about 55 mph when the bike cut out for just a split second. A quick glance down and the speedo was swinging back up to my road speed so it must have dropped to near zero. I continued my ride with no further issues. I rode about 35 miles hitting speeds up to 80 mph and the bike seemed to run fine. Upon reaching home I ran the diagnostics and found codes P0131 & P0151 (frt & rear O2 sensors low) and the codes b1006 & b1007 but I can't seem to find what those mean. Anybody know? Thanks.

 

years ago I had the same codes:
B1006 Accessory Line Overvoltage Instruments
B1007 Ignition Line Overvoltage Instruments

Checked and cleaned all my grounds at the battery and engine/frame. They were slightly loose and oxidized. Cleared the codes and they didn't come back (was told I was lucky that it didn't take out the stator and or the voltage regulator?)

 

Thanks for the info. I'll check them out.

 

I second the battery connection check.. what you describe is a classic sign on a loose connection

 

Yep. I found the + screw had vibrated loose. All other connections are clean and tight.
I'll take her for a spin tomorrow and see how it goes.
