Yes (if you don't put the ground clamp somewhere stupid)
The welding didn't damage the electronics that was affected.
Your bike electronics are almost surely better hardened than the sprinkler controllers or MP3 players because a normally working bike is not a good RF environment. There are spark plugs firing many times a second which are a significant EMI source and vehicle electronics in general are engineered better than sprinkler controllers.
