Hi I think that its the spacing of the magnets inside the flywheel. There is a gap, well slightly wider spacing at one point and i think the CDI can 'see' the gap.

At least thats my understanding anyway.

Check the resistance of the magneto stator coils

Pulser white/red to black = 12.4 Ohm +- 10%

Source coil, Brown to black = 420 Ohm +- 10%

I wondered how the pulse occurs at the right moment too, dont worry too much about it though, just check with a strobe light and you will see it is correct. there will be some lines on the rotor and a line on the casing.
