No you do not.
For Thorspark all you need is good bearings and accurate alignment of your drive pinion with the intermediate pinion, good tight straps to hold the mag and dyno down
Strobe your timing and good to go!

I have put it all back together but it sounds like something is rubbing and it does not spin freely. Thanks for the info neil1964 and Rog1.

The magneto cover at the points end may need to be shimmed out a little. Undo the screws and nuts a few turns and see if it frees off. If so, I think you can make a thin card gasket for under the cover that will give you enough clearance. After all, the bearings are secured in cardboard so it should be alright.

Thanks Rog1 will give that a go.

As above (for some reason my previous reply did not post!)
You only need decent bearings and fit of your drive pinion with the intermediate pinion and good straps to hold it to the platform.
You will need the advance retard to work and a strobe.

Thanks neil1964

This switch is on the battery side of the ammeter, and disconnects the battery, the new ignition circuit and the lights; I can't forget to turn the lights off then come back to a flat battery.

Sorry folks! I made an error here; I should have written:

"This switch is on the battery side of the ammeter, and disconnects the new ignition circuit and the lights; I can't forget to turn the lights off then come back to a flat battery."

This means that the switch does not disconnect the battery from the ammeter, and does not disconnect it (at least on my bike) from the horn or rear brake light.

I have put new bearings  in and the  inner race bearings . I have made a mess of the slip ring  do i need to replace it or can i leave it out as i am using the thorspark.

[JulianS]

The slip ring spaces the bearings so you need to leave it in to do that.

[nige63]

Ok Thanks JulianS. I will put the broken one back in as it is still whole just a few bits missing on the outer edge.

Any one know if you can still get the oil flinger
