What jumper method? The side stand switch? The clutch switch? Both?...Tried the jumper method on my gen2 and still no joy...
Both switches must be activated to provide a path to ground for the starter circuit relay's coil. You should bypass them both.
If you have bypassed them both, then there is a bad ground path, either in the BL/R wire going from the relay and diode matrix to the clutch switch, the Gr/W wire going from the clutch switch to the kickstand switch, The LG wire going from the diode matrix to the neutral switch, or the Gr/Y wire going from the side stand switch to ground. Check them for continuity.
