Hi all

I have been searching the forum and can't seem to find the answer.

I seem to have a whining noise from the new mag since fiting it to my M20.
Could some one please tell me how to correctly fit the mag and how i go about fitting shims underneath it to make the gear sit correctly.

Thanks

there should be a bit clearance between both gears when fitted the magdyno with the strap tightened.......when there is no clearance ad a shim and fit again until you feel a bit play between the both gears.

Hi Roy

Thank you for the reply, i will give it a try this weekend.
