tacho speedo and neutral light not working

This could be caused by a wire shorting from the ignition barrel, running down the side of the headstock. Had this problem with my speed triple, on left hand lock the wiring is tight and can cause a break causing the problems you describe. The fix is to take wiring out of clamp alongside headstock, locate break/short,re-connect and re-tape. Leave the re-connected wire outside of clamp to allow extra play so problem does not occur. Good luck
