Hello,
My bike wont stop running even with the ignition OFF. I had to pull the battery in order to stop it.
After a bit I plugged the battery back in, with the ignition OFF and the starter motor started turning immediately. Bike did not start. Then, I switched the ignition to ON (without pressing the start button) the bike turned over. While it was running i noticed a loud humming noise sounded electrical.
So i think it might be that the starter relay is getting stuck?
