I was making a right turn in 1st gear and applying small throttle for traction but the engine cut off during the turn. This is dangerous for a motorcycle as friction and throttle is needed for a safe turn even during slow speeds. I have raised the concern to a local dealer prior to this incident. I called the local dealer and they stated that the open recall had already been completed so there is nothing else to do. There are a few youtube videos and many comments about this being a common issue.
