AT1 1969 magneto / starter was created by Jogar

Hello everyone, I’m on the search for the entire magneto / starter assembly for my AT125. 

the bike came with no magneto attached. Didn’t see any on fleabay, so I’m shooting my shot. 

anybody got a spare one could buy?

thanks, 

 Johnny

Do you mean generator/starter aka dynamo/starter for the 12v electric start model?

(In some countries they had a magneto AT1... USA only got the 12v generator/starter model but some have been modified or brought here from other countries)

One easy way to tell is if the crank stub has internal threads for a bolt to thread into, it's a generator/starter model. If the end of the crank has a threaded stub that takes a nut, then it's a magneto model.

Here’s a pic, I’d guess generator starter then? Kind of a bad quality photo..

Yep she's a starter generator one [short internal thread crank]. Might be best to go for an aftermarked flywheel mag these days of which MarkT above might be able to advise you which type is best.
We had the electric start when we got the first models but got magneto models too, of which i have one.
If you wanted to retain a start/gene type there's a lot to consider with wiring & charging/starter activating components. Magneto [cdi modern mag] new system would have the cdi box with it & maybe come with a regulator for battery charging for lighting. But no battery required to run it where the Gene model requires a big Bat for the starter side.

Yes, what RT325 said. Generator.

Next question is your plans for the bike? Is it in good shape overall? If you can't find a good used generator/starter, already have the stock wiring and lights, and want it street legal, a VAPE CDI might be best.

If you are building an off road trail bike... or street legal and don't already have the lights, etc... and especially if you need to split cases... I'd swap in a CT1 crank and magneto ignition... but then I have all the parts to do that laying around.

The bike is in great shape, original everything by the looks of it. Looks like The prior owner has bored the jug to house a .50 piston, and that’s brand new. 

where does one purchase a VAPE magneto, and are there any other diddies I should be aware of before I commit?

do they make it simple for a simple fellow like me?

And…. I believe I’ve got a ct1 ‘73 crank in my garage …. Less wiring / CDI headaches if I do the swap?

Again, depends on what you are doing. Trail bike or back to stock with all the lights.

CT crank just lets you use a CT points magneto which is probably cheaper than VAPE. But 6v instead of 12v.

Big benefit of magneto in my book is doesn't need a battery for spark.

Okay, so I ordered the VAPE kit , I believe it was listed under DT125, (saw that on another post of yours).

*not sure what the plan is for the bike yet. It’s in pretty good shape, so I almost feel it would be a shame to mess with it and restore. (Someone once said restoring a bike is like dying your whiskers). I’ll see where it takes me? 

I’m planning on filming myself figuring it out, hopefully that can help future people on here not make the same mistakes I did! 

They also don’t waste any time, it was shipped this morning! 

so with the VAPE I will still need a battery, correct? 

I’ll keep you guys posted, thanks for the help so far! Appreciate you all.
