Just got a Leoncino 500 6 days ago and waiting on my parts to arrive. i havent used it yet because im waiting on my crashbar. I am also looking for help in tuning and reflashing my ecu and changing the normal digital display to a tft one that i ordered from speedpark.
I have had this issue for a couple months now. It is driving me insane and noone is able to figure out where this sound is coming from. It sounds metallic and only happens when you go above 4500 RPM. I can only describe it as a zinging/buzzing noise.
