Hi, i had no damage visible but did go through 2 brand new sensor boards in the motor before sending both the motor (speed passion v3) and speedo (nosram pearl istc) back to schumacher.
They checked them both out and confirmed that a F.E.T. (field effect transistor) in the speedo had gone bad and this was in turn blowing the sensor board in the motor.
Cut a long story short, they replaced the speedo with a brand new one and put a new sensor board in the motor and everything has ran perfectly since, even some big wipeouts racing wont make it skip a beat.
Good luck sorting yours and have the speedo looked at properly as it was impossible to find the problem myself. it blew sensorboards in 2 different speed passion motors.
