Digi Speedo Magnets

[Johnnybizzle]

Hi Guys,

Finished mounting my digi dash and speedo pick up ive now got the task of sticking magnets in place to the sprocket adaptor flange, got six magnets in the kit tried all six but way out on calibration, guna keep trying with fewer magnets till its right, does any 1 know how many to use and what spacings (equally i assume) to save me some time????

Regards jono
