Rear disc and magnets.

[BRH]

Hi, can anyone help ?
Iv brought a new wavy rear disc for the M1100, but it does'nt have the 4 magnets that run the speedo ! It has 4 holes where they could go.
So IF I could find the magnets to fit in the holes, how could i fix them ?
Or could I use magnetic bolts to hold the disc on and hope they run close enough to the sensor for a reading ?
Any help or ideas !

Thanks.

They are not magnets, just iron. On the OEM disc they are riveted and are not on the same diameter as the bolts so they will not align with the sensor see pic below.
Your best bet is to get some machined up with an interference fit on the reduced end that fits in the disc then rivit over. A bit of red loctite would help.

Could you run some cap head bolts with a nyloc nut on the back of each one? I only suggest this as a ghetto fix in case you don't have access to any engineering kit.
