that didn't go as planned.
took the bike out today for a commute.

never made it to work, started fine but an the highway it threw a S85 error (motor sensor) at me twice.
limped it home again.

ah well back to the lab again.

Hopefully final update.

Did some voltage and current messurements today, no current flow what so ever from the motor housing to ground or anywere. so that,s good.

after that I went on some agressive driving, fast acceleration, high speeds, hard regen, drifferent modes and gears.

no error codes!

it's now charging for a ride to a job interview tomorrow...

Hi Leander, can you tell us if your bike is running ? I am interested in which o-ring as been replaced and how you put back the motor without recalibrating the sensors ? And finally where did you repair your motor ? Was it in Europe ?

Thanks a lot!

Bike is running fine

the o-ring that sits behind de (in my case gold) aluminium motor cover where the sensor is mounted on.

no recalibration done. just left the encoder on de cover itself.

it's been reapeared at a Electic motor revision company  in the Netherlands that normaly does industrial motors and servo's
the empulse motor was handled like an servo motor because of the sensor.

If I get the chance I will would like to do a calibration check and a software update.

Thank you, I may try the fix. I am a little bit scared to move the encoder but I guess it's this or I live with the leak forever. I will also need to open the motor, measure and order the o-ring then few days without the bike. Also oil and coolant drain before opening the motor.

just leave the encoder on the plate and it will be fine.

just 1liter of oil (complete change)
and a bit of cooling fluid.

o-ring is a big one but standard

keep in mind you need an o-ring that can handle the heat and the cooling fluid chemicals.

leave the rotor in the stator.
