Ignition System HMB-Z01 for T3, LM-1,2,3, SP etc.

Is there a need for another ignition system in addition to those already available?

Yes! Because until now, the only choice was between systems that were either:

Completely proprietary, fully electronic systems that cannot be easily repaired on the side of the road in the event of a failure. While these systems offer advantages such as electronic ignition timing adjustment, etc., they eliminate the distributor or render centrifugal ignition timing adjustment obsolete.

Or:

Simple systems such as Piranha, Dyna, or Newtronic, etc., which are based on the distributor and retain centrifugal control. This has the advantage that, in the worst-case scenario, they can simply be swapped out for the spare contact plate carried in the vehicle. A major advantage!
But these simple systems also have serious drawbacks:

Workmanship.
Anyone familiar with the Piranha or Newtronic, for example, knows about flimsy plastic connectors, water ingress, etc. Other British systems are better in this regard, but are repeatedly plagued by failures.

Although we (like the simple ignition systems) are based on the distributor—which means they can be quickly replaced with the breaker plate even on the road—we offer the following advantages:

1. Workmanship and compatibility:

Our system is waterprotected, the housing and connector are made of metal.
Measuring 9 x 3.8 x 3.2 cm, the unit is very compact and can be mounted out of sight for applications such as café racer conversions or open frame triangles.
The wiring is designed so that a switchback to a mechanical distributor can be completed in as little as 10 minutes, even on the side of the road.
The systems are 100% manufactured in-house, and all individual parts are available in the event of a defect.

2. Ignition timing adjustment:

This can be done statically while the engine is at a standstill; two LEDs indicate the respective ignition timing. This can also be done on a cylinder-by-cylinder basis for maximum accuracy. Of course, this should be verified with a strobe light.

3. Sequential ignition:

As with the breakers, ignition occurs only during the usable top dead center (TDC). Many other ignition systems fire “empty” into the overlap TDC. While this does work, these systems fire twice as often as necessary. This also results in unnecessary heat generation, power consumption, and premature aging of the spark plugs and ignition coils.
In extreme cases, this is also a safety concern. Unnecessary firing during the overlap cycle has already caused fires. A Guzzi Guzzi  owned by one of our customers (LM-2 with funnels) was involved in a low-speed collision with wildlife. It ended up on its side with the engine still running. Gasoline leaked out and it caught fire. Why? Because the intake valve is slightly open during the overlap stroke, and the (unnecessary) spark then ignited the gasoline on the road.
Admittedly, a rare scenario, but that’s exactly how it happened.

What it can’t do, and why that’s still an advantage:

That’s the advance ignition timing. It’s achieved mechanically, just like with a distributor. A disadvantage? No, absolutely not. Because the centrifugal adjuster in the distributor hits its mechanical stop at 4000–5500 rpm. This means that when it really counts, the ignition timing for both cylinders is absolutely precise. Before that, the springs in the adjuster are decisive—sufficiently accurate and without delays, unlike fully electronic systems. These often have to calculate the ignition timing first, which is always associated with a time delay, especially during acceleration.
And yes, a distributor does have some play. But that doesn’t matter, because during acceleration or at a constant speed, the play is virtually zero. The play would only occur during coasting, which is absolutely irrelevant here.

Conclusion:

An affordable ignition system, superbly crafted, and field-replaceable. Detailed  instructions can be found HERE.
