A while ago I posted about the points replacement for Vespa’s.
The other day I decided to learn more about them so I sent an email to the guy who has them over in the Netherlands (Tonni from vespa-ciao.nl) asking about how they worked and if he would ship to America.
He replied the following:
The chip works by picking up the change of polarity of the flywheel.
Then it reacts on the strongest peek of electricity, which is in the
case of the chips about 20 degrees before TDC. This decreases slightly
when the RPM goes up.
I have not noticed a rev. limit on it, and till yet never heard someone
that the have.
The only ‘problem’ with the chips is that they are very sensitive. The
circuit needs to be in very good shape. Also the spark plug has to be
set at an 0,40 opening max. The spark is smaller as what you’re used to.
In most cases it runs nice and gives good results. In some cases though
it doesn’t work perfect, we can’t really figure out yet what the problem
is in those cases. My guess would be an inferior quality ignition coil.
We currently have two types of the chips. Both types work the same, one
has only one (+) connection and the other is also suitable for reverse
(-) ignition types. This one also has an aluminium housing and is a
little more expensive.
Currently we’ve been testing to fit the chip right at the ignition coil,
this makes it easier to replace if broken and it stays cooler if it’s
not bolted straight on the engine.
Hope this info is usefull for you.
If you’re interested, we could arrange a delivery to the US, no problem.
Sounds pretty rad. When I get paid next I’ll probably order a set anyone else want to get in on a set?
This is how to wire in the Hobbit CDI
The Ground prong needs to be grounded.
The kill switch goes to your kill button which then should go to a ground.
AC Ignition power is from the stator and is the wire from the coil that is mated to the pickup IE the extra wrapped/insulated coil.
The timing trigger is the wire from the stator coming from the pickup.
The ignition coil prong goes from the box to your universal coil.
a hobbit headlight. I also need a ht coil for the gadabout. I have monies. Help a brotha ride again.
