Reply To: Gt125r headlamp too low
You could start by making sure the engine side panels are off the frame (put a carpet or something under the bike)
Unscrew the side panels (just the sides) then it will come down on the floor with the middle grill still attached to them (easier)
After that you are left with the top side panels still attached to the headlight brace, so use this diagram below to help you with disassembly/refitting.
The mirrors can come off during this process too.
Hope that helps.
