A few thoughts:
1) The right mag is equipped with an external starting device, either a
buzzer or a SlickStart presumably. I would be inclined to carefully
inspect the shielding of the wiring related to that. The HT leads and
plugs also need careful inspection of course. A loose cap, a corroded
lead etc may cause a spark to occur where it shouldn't and so generate a
tick.
2) Can you tell if you hear one tick per revolution of one tick per four
revolutions? That would tell you whether you are looking for a primary
side, or an HT/plug related issue
3) Are your 'P' leads long enough to swap from side to side? Doing so
would again isolate the issue to the starter system and wiring, or the
magneto.
I suspect you are going to have to narrow things down by
swapping/replacing/inspecting.
