Lower fairing .
The one on mine was very flexable and wobbly. especially where the exhaust manifolds pass by. To over come this and make it less flexable was easy.
All you have to do once removed, is mix up some fiberglass resin wid the hardner and place the panel in a position so the mixture stays whee you want it. Then simply pour it into the area , you can brush it around if you want and leave to set.
If any bolt holes are around the area, cover with tape on the out side then re-drill once mixture has set.
Put back on and you will fel the notice the differance.
