My intention to build a low weight sprint racer called for a light weight ignition too.
For a while I considered building one by myself but I came to the conclusion that a professional ignition would likely be my best option and I chose a PVL that seems like a good ignition.

Not able to find any answers to how to put this ignition on the engine I have began to do the installation this way.
Note that it´s not complete yet and I may find problems later on but this far I´m pretty confident.

The Ciao engine is not really a high tech wonder as you may know.
I wanted to have a decent ground to start with and also having a known circle to build from:

To create that I put the right crankcase in the lathe, beginning with aligning it from the bearing.
I think that one tenth of a millimeter is close enough and that was no problem to reach.

Here you can see when the machining was almost done.
Note that I had to have the lathe spin the opposite direction to make a right angle in the center:

This is how it looked when I was done, the supports for the ignition bolts and also the left support
was in one line with the plane close to the crank.
I desired this to be able to get a reliable center aligning:

I ordered a plate made of two millimeter stainless steel, lazer cut with high accuracy.
The dimensions are 100 mm OD and 29 mm ID, making a perfect fit on the machined center steering.

The plate was drilled to fit the bolts for the stock ignition:

Next step was to make a spacer for the ignition center:

This is how it´s meant to be used while I figure out where to place it:

My recent step is to adapt the rotor to the crankshaft.
The easiest way i could think of was to use the center of a stock flywheel and adapt the PVL rotor.
To do that I wasted a useful crank like this:

On top you see the shaft.
Under that to the left you see the center of a stock flywheel, in the middle a spacer and to the right
you see a nut to keep the pieces in place when I will do the machining of the center to fit the rotor.

I will keep on updating as the work goes on but it may take a month or two till I get to the point of
starting the machine so please be patient.

Have you seen a PVL on a Ciao engine in the netherlands before?
I asked for opinions but no reply this far.
