To set the timing,using a dial gauge

Remove head & flywheel cowling, then screw dial gauge into cylinder head spark plug hole,

Rotate the flywheel until you find t.d.c. (top dead centre), when you have found t.d.c. set the dial gauge to zero.

On the outer lip of the flywheel fins there is an arrow, which faces the outer edge of the magneto flange.

Make a notch on the magneto flange opposite the arrow on the flywheel.

From the t.d.c. mark, rotate the flywheel anti-clockwise so the dial gauge rotates to 2.0mm for gp for li/sx electronics.

At this point make a notch against the arrow.

Rotate the flywheel until the dial shows 3.0mm corresponding to 23 degrees btdc

Mark the third mark on the magneto flange

Looking through the window on the flywheel the two lines inscribed on the outer edge of the flywheel should match up exactly with the two lines on the stator plate pick-up box when the flywheel is at b.t.d.c. (before top dead centre)

When the two lines meet up exactly your timing is set.

When the two lines on stator plate and flywheel do not match up you will need to remove the flywheel, slacken the stator plate bolts and move the stator plate in the direction needed to line up the stator and fly wheel..
