I have removed my Horn bracket and fitted my horn to the Front left of my SV curvy,
This allows me to move my Radiator forward easily without having to remove the Rad hose or drain coolant,
The piece of card on the Rad has some double sided tape on it and I use it as temporary protection for the fins and my knuckles when working on my Front plug.
I use NGK Racing straight Plug caps,
