Hey bro, greetings from Georgia!
Haha, anyways, to fix the turn indicator noise open up the left ferring (looking from the front of the bike) and tape up the black little box thingy that makes the noise. Use electrical tape. After about 3 wraps my bike just makes a satisfactory beeping noise instead of the sound a semi makes when backing up.
Also, for the flashing problem, someone told me in another topic that there is a certain wire you need to cut/unplug. I am yet to look for the wire but here is the link for the diagram of a LF200:
