With that many DTCs on a bike that's still running, I'd guess a bad ground connection.

First check the battery negative wire. Then check the screws for items 1 and 3, and then the screw for items 8, 9, and 10 shown in this picture:

Then check the engine ground connector to the frame shown here (it runs from the oil sump to the frame cross member):


The B1005 DTC is usually an unplugged fuel sensor or a short to voltage on the Y/W (yellow with white stripe) wire that connects to IM (instrument module) terminal #11 but this shouldn't affect the engine's performance.

You should have mentioned that you were using a PC V in the previous post.

I would have mentioned to check that before the ground wires.

thanks for your help
