Hello,
I am not so very familiar with my Laverda, so I would like kindly to ask somne advice. I have Laverda 1000, year 1974 with HKZ ignition. For this next summer driving I have planned to assembe electronic ignition and at the same time to lift the altenator output as the electronic ignition providers offer the solution. Can anybody tell;
- Which one is better - Sasche Electronic system or DMC (Moto-Witt)?
- Do I need a voltage regulator and must that be one phase or three base model?
and one question also concerning the external oil filter
-If I assembe external oil filter, do I need more efficient oil pump? ( from Laverda Paradise) or can I use the normal original oil pump?
- How important it is to keep the oil level under the stick mark?. Last summet I faced an oil leak, when I have too much engine oil in the engine.

Best regards
Restomoto

Erkki,
I'll give you the answer on the alternator/ignition as I manufacture the conversions.

To change out the ignition and to upgrade the alternator you have no real choice but to purchase a Redax/Sachse system.
The DMC unit does not change the ignition pick ups and most you can do to the alternator is upgrade from 130 watts to 150 watts by changing the twin coil pack to a larger single pack.

On the system we make, we have been using 250 watt alternators and stators from Kawasaki 250 Ninja's which now gives you 3 phase charging system at 250 watts.
New 3 phase regulator is supplied with the system.
We change the ignition to a custom made Sachse hall effect ignition system that comes with 9 pre-programmed ignition curves and an ignition test circuit.
Have a few of these systems left in stock and are available at the moment.

However, we are about to release a 320 watt charging system using all new components which will use the same Sachse ignition but is most likely still 6 weeks away from release, am hopeful of doing final load testing of this system today.
Here are some shots of the new system, is not much different to the 250 watt system we have been selling for years.

Hi Redax5,

Thanks for your info. This seems to intrest me as I didn't know about this system. It is a little bid different than Sazche electronics
(www.elektronik-sachse.de)
Does this your kit also include ignition coils or do I have to use the old ones. Are you so kind and inform the content of the Redax kit and the value. I think that 250W is efficient enough.
Do you have any www-pages to look of this more and have you also all the instructions how to connect wires etc.

Best regards

Hi Erkki,
For your system we supply a new coil mount that bolts onto your existing bracket at the headstock and also supply two replacement coils.
These are TEK coils, 1 x single and 1 x dual.

we supply a 6 page document with the installation instructions with the system.
is quite straightforward to install.

We supply the Alternator, Stator, 3 Phase Regulator, new Alternator puller to suit the new Rotor, majority of the required wiring, Hall Effect Ignition of course and all the required adaptor plates and bolts.

You can purchase these systems direct through us (Australia), Keith Nairn (Scotland), Scott Potter (USA) or through Volker Sachse (Germany)
Send us an e-mail to redax(at)squirrel.com.au and we will send you the mounting instructions for the 250 watt system and pricing structure.
I have not made an instruction sheet for the 320 watt system yet, is on the list of things to do.

Hi Erkki,
I've been using one of the first (if not the first Sachse/Redax-System at all) in Europe. That time it came with opto sensors, the new kit has hall sensors which are more robust (although I didn't have any problems with the optos).
The ignition box is the same as on Volker's web page but the charging system is totally different.
The 250W provided are absolutely sufficient even if you do not revv up too much and have your H4 head light always on. In addition you will swap your truck size battery to a more modern one (smaller and less weight). I am running a Hawker Genesis 16Ah for several years now without any problems (using a Shindengen 5xxx something R/R from a Kwaki.)
If you want to a modern ignition (smoother curves and less power consumption) AND more alternator output the Redax/Sachse-Kit is the perfect (and only) solution. The new 320W will also feed heated grips  ;)

Best regards

Redax..will the Sachse "inducer" that fits on the crankshaft work on an early 3c that doesn't have a locating point drilled into the crankshaft? The early 3c bikes had the OEM Bosch inducer held in place with a spring locked into a grove with the flywheel. Restomoto's bike is a 1974.
 
Rusty,

The Sachse inducer is held to the crank by a couple of tiny grub screws, don't need the factory indent or the flywheel keeper.

the Hall Effect rotor that carries the two magnets is held in place by three grub screws
fits on any crankshaft

we finished testing our new system yesterday, was able to load the unit to 300 watts+
tested using Drikko's RGS as a base line
everything worked out pretty well, am well pleased

Romeo, last time I checked Silent's website he is not showing a system to suit a Laverda Series 1 triple.

I already have the DMC ignition installed, is the 250 or the 320w alternator compatible with the DMC box ??
Click to expand...

no, our system is not compatiable with a DMC
on a Series 1 engine the DMC relies on the standard Bosch reluctor style ignition triggers, the Sachse ignition uses Hall Effect triggers
totally different style and form of signal

there is no room available when using a full style of alternator/stator to retain the original Bosch triggers, I have a space of around 12mm to fit the ignition triggers into
hence the Hall Effect system
 
Thankyou a lot to all.
I am well informed now and I have detailed info also.
Have a nice time in your carage, We are also waiting spring here up in the North (Finland)
Best regards

Hi to all ignition lovers and converters:

The last post is almost 6 years old wherefore I think the topic needs an update because of lost alternatives (Redax-Sachse / IIS) to change the original ignition.

Which choice do Laverda 1000 owners with the original HKZ ignition (alternator and pick-up plate on the right side) have today once they like to replace the old BOSCH system inclusive the alternator and rectifier against a precise ignition and generator which produces up to 320 Watts?

Would be happy to get a recommendation with your critical reflection

As far as I know Redax  is still supplying ignition/alternator upgrade kits for Bosch alternator / HKZ equipped bikes.  I'm sure Red will chime in - or contact him directly via Personal Message (redax5 on this forum)
