As I am retrofitting a 84bore cylinder I need a new second spark plug hole in my cylinder head for my decompressor
Its not something I have done before but I have a mill and an angle plate so...
I have worked out is a 14mm X 1.25 tap and a 12.8 mm tapping drill but does anyone know the angle from the cylinder base of the hole? by eye it looks like 45 degrees.
