Reply To: GT650 EFI leaning out
The only means I have to check the electrics is with a multimeter.
Just to digress a little, the manual only shows a two bolt TPS and not a 1 bolt. The pins appear to be upside down on the actual bike compared to the manual.
The fuel pump was replaced with a new unit.

The temperature has 3 bars on the dash. Before replacing the coil the rear cylinder felt noticeably cooler than the front.
