As for running LEDs in the indicators you will need a different flasher unit, the OEM flasher operated on lamp current. The current would heat up a bi-metal strip which would bend so the contact sprung open then cool down to close and repeat the process. The only way to make this flasher work with LEDs is by adding huge resistors to take the place of the incandescent lamp load, this is too crude.
With LEDs you need a flasher unit that will open and close at zero current, these flashers normally have a third wire connected to chassis.
Then you need to re-wire the idiot light, it came from the factory connected between Left and Right indicators the current drawn was insignificant compared to the incandescent lamps in the indicators, about 100 mA but with LEDs that tiny current is many times what the LEDs draw.
All you need to do is wire a small diode from each side pointing at the idiot lamp with the other side of the lamp to chassis. The diodes prevent the lamp signal getting from Left to Right indicators, even if you change the idiot light for an LED you will need the diodes. This change takes place inside the dash, no additional wires except the new ground for the lamp.
If you decide to change out the incandescents in the dash for LEDs don't even think about using the original lamp holders.
BTW, if any of you also have a CARC Guzzi you do need to add a shunt resistor (just a tiny 1K 1/4 Watt) to some LEDs to keep the lamp alarm happy and stop the lamps glowing with the key off.
