Joe Hunt Magneto for Atlas

When talking about Wassel are you referring to the housing, the electronic ignition, or both? I know that the Tri Spark kit with housing that RGM sells includes a housing by Wassell. How is the the housing that Joe at Eurotrash sells different?

The ignition setup procedure is what I was talking about. Essentially the Trispark is a tidier package and easier to setup than a Wassell ignition.

No clue about the housing differences. Could be the same.

My bad... I didn't check RGM for a complete kit. I knew they sold the AAU replacement gear. Only reason I knew that is gpzcat posted about it when he did the magneto ignition replacement. If I were doing it, I would get the TriSpark kit and the gear to replace the AAU from RGM now that you have shown me the way. One stop shopping more or less.

The ignition is Wassell but I don't know who makes the housing, it was unbranded, if memory serves.

There may be a couple of makers, or there's been an update to the design. The first pic is different than mine, it's from a bike that sold on BringAtrailer. The second is the one I got from Eurotrash. As for my type, it was noted on this forum that it's not very waterproof but could be modified to seal well. I don't ride in the rain and where I live it's not gonna sneak up on me. The one from Bringatrailer may be better in the waterproofing, I am not sure of its pedigree.

I looked at the Thorspark and it looked interesting. IIRC, my housing's bearing was shot, and replacing seemed to be no simple task. So that ruled it out for me.

Thorspark would have been perfect if it had been around in the 70's. ha

Yea I cane to the same conclusion on the Thor. For me its either going to be Joe Hunt or Tri Spark. Roger at RGM mentioned yesterday that for current electronic ignitions it’s best to have a current updated charging system. If so that drives the number up.

He might be referring to a solid state regulator rectifier, and yes a good one like the TriSpark MOSFET reg/rec is not real cheap.

As I may have mentioned, I use a TriSpark ignition in a Commando timing cover points housing on the P11, but my alternator is the same one I installed and has been in the bike since I got the basket case running in 1973-74. Hard to believe it still works, but it does with the TriSpark reg/rec and my battery choice. Point is you may not have to replace all the charging system components unless missing. Also helps a lot to minimize the wiring a much as possible and use LED lighting.

I know I'm not telling you anything you probably don't already know. Consider my babble encouragement.

Edit: Don't add up the receipts.

Spoke to Joe at Eurotrash and what he sells is Wassell probably made in then Orient. Thanks for the input

One last question for those of you that have fit an electronic ignition to an Atlas. Where did you mount the coils?

On my 650 they are between the battery box and oil tank. EI trigger is an a K2F mag body at the usual place

That's very interesting. What was it about the Hunt mag that made it the winner?

Big fu cking spark, easy to work on and first kick every time, no need for a battery or coils as all built in the JH, point, condenser and coil all under the front cover.

Ah huh. Well that’s the conclusion I came to as well. Actually looks good as well
