I don't know about this problem but in an attempt to put you out of your misery...
If both indicators don't work then it might be the flasher unit (don't ask me where it is - under the seat perhaps?) - The Indicator switch - the wires that join them together - a fuse - again very probably under the seat - they are on My MSX 125.
People here can not see your machine or apply any diagnosis - you need to do that yourself - begin by looking at things - then use a test meter to check for voltages and continuity.
If all this is too much for your confidence and knowledge then take the machine to a repair shop - use hand signals as you ride there.
Good luck...
