I soldered the LEDs to a protoboard with 510Ohm resistors in series (as the LEDs are 3V max /20 mAh). The black ground wire is looped here for testing, but the final version has ground wires. One in common for turn signal/high beam, and one to ground the oil light. I bought quality LEDs, but they can brake so i made the oil pressure light (skull) reduntant and with separate resistors.

The switches are reconfigured:

Left is:

1. Lights. Short press - blink high beam, longer press - switch high/low, even longer - turn off.
2. Turn Left. Short press - blink 3x, longer press - blink continously. Stop with short press.
3. Turn Right. Press both 2 and 3 for hazard lights

Right is:

1. Start. Read below.
2. Horn (Can also be used to configure M-unit, but I use my phone for that)
3. Motogadget Mini operation (configuring and switching between infoscreens)

The keyless start is configured like this:

• Approach the bike with bluetooth turned on and mo.ride app (service) running on your phone. The phone will connect to the bike and a (turn)-light signal will tell you it's connected.
• Push start x1 to turn on bike. Motogadget Mini display shows startup animation.
• Use starter button to start your engine. Light turns on automatically. Light can be turned on an off by holding light button
• Press Start x2 to stop engine.
• Press Start 2x again to turn off ignition

In the video I'm testing the system without starter relay connected.

The display can be configured for both horizontal and vertical use.

When doing th R1 monoblock-swap, there is a choice between switching from 298 to 310mm rotors, switching to 320mm rotors and using 5mm spacers or milling 6mm from the calipers at the contact point (red markings on image).



I don't want bigger rotors, as I think they look out of place on these bikes, so I'm choosing the last option. I will post the result later this week

Thanks for hanging in there and updating the thread. Looks great.
