Phase sensor gap is 0.2mm to 0.3mm.
The wire is correctly on when the top wire from the sensor goes to the nearest pin on the through connector in the dizzy body, you MAY have to gently bend the base of the phase sensor so that is is PERFECTLY parralell to the LOBE.
The cranks sensor is easy and gap is 0.6mm to 1.0mm, though they wil still work way outside this range.
CAUTION when setting crank sensor gap, check on ALL lugs, as if you set on a low lug(may be chipped/worn) then when a high lug(unworn) comes round it could clout it!!
