Sachse ignition for 100s and 75s ?

I seem to remember Sachse used to do an ignition kit for the 100/75 tiddlers.  With the tragic death of Volker, I presume that several kits have been dropped as I can't see the kits on it.

Can anyone tell me if the new owners are willing to do one-offs or old patterns?

not certain if Marco will do one offs, I have 2 of those systems in stock so could send him the details
the 2 systems we have are not for sale, I bought them ages ago for our own 75 and 100 bikes that I fully intend to restore one day once all the customer engines are done

I'll look at taking some photos and dimensions and send to him for you
 
I may well be wrong but an electronic ignition for the 100 or 75 would require an auxillary battery for the ignition which would run as a total loss system. These bikes have a flywheel magneto which doesn't generate sufficient power. The battery on the later 100's is there to provide additional power to the lights so that when you brake the brake light doesn't dim the main beam. Again I don't think the battery is actually charged by the circuit.

There isn't in my experience anything to be gained by ditching the conventional setup as you don't need a multitude of maps for such a simple engine. The only reason I thought about it was because finding replacement points is a nightmare - if anyone has a source let me know!

Cmon! These machines mopped up everything on the gruelling Milano Taranto, 1600 km, and that with points.
Be serious.

That's the point  ::)

:) Parts are pretty tough to find for the tiddlers  and consumables like points aren't going to keep going forever; that's part of the reason I asked (apart from wanting to treat it to shiny new kit  :D)

P.S. Paul is right though - utterly astounding feats performed by men and machines in those days

P.P.S. How about a separate Tiddlers section again to share knowledge and parts sources etc ??
 
The more squeamish amongst us may turn away now, but i've had good results on small Italian engines grafting on rotor and stator from Honda scooters...The 100/125 Lead scooter is electric start and crank triggered ignition. Alternator output is certainly more than adequate to keep a 12v battery charged. The ignition is in typical Honda fashion triggered by a lump on the rotor so you need to have room to mount an external trigger. A plus is that the system is common to both 2 and 4 strokes so by choosing the correct ignition box you can have the curve you want.
Rotors are about 115mm OD so not that big...

Two guys here wanted to do the Moto Giro again but both had suffered ignition problems on the bikes they'd leased. They were determined to go back with something bulletproof so I built them  Aermacchi and Benelli motors using the same ignitions and charging systems on each - and supplied a spare too.
 
Awesome stuff Greg - cost effective solutions to updating the bikes for modern conditions  :)

I would suggest that if you can't see it and it works better than why not?

We'll all have to find more creative answers in the future as parts become rarer and rarer...Honda XR100 pistons anyone?
 
The 100 Sport Lusso and GT models already use a battery so the Sachse system would be a sensible way to go if you can get your hands on one and your points are worn past the point of no return. The original points do seem to hold up quite well. My Tourismo which I loaned to Scott Potter for this years Milano-Taranto ran great all week with the exception of one expired condenser. I checked the points gap and timing a couple of times during the event and no adjustments were needed, even after 1800 kilometers. To make life easier I've remounted a couple of condensers to the frame rail behind the tank. It's all out of sight but their access is easy and you can swap the wires over without having to remove anything.

And I needed to set them every evening, after only approx. 400km/day!  Fitted new points before leaving, points cam shaft has no slop, but engine vibrated more and more towards the end of every day.  Sure enough, timing was out by several degrees.  Pointless ignition is top priority as far as I'm concerned.

How these engines survived the abuse back then beats me... in Taranto, they couldn't have had much more than 50% of the power they started off with in Milan.

Hi Nick and all tiddler fans,
I bought some replacement points for LAVERDA 75/100 recently - NOS - KING Made in Italy. I can offer 8 sets. One set is EUR 20,- + shipping costs. PM me or email me!
Ciao, Gert
