About CDIs

Let's take a quick look at the subject of CDI. Why replace a CDI?
There may be a number of reasons for this:

- Your scooter suddenly stops in the middle of a ride and doesn't start again. (electric starter does nothing.)
- Your scooter does not start anymore.
- You want to return or increase your scooter.

First of all, the difference between the CDIs of two-stroke scooters and those of four-stroke scooters:

In the case of a two-stroke, a CDI has no influence on the top speed of the scooter.
In the case of a four-stroke, a CDI does affect the top speed of the scooter.

In a four-stroke, a CDI does have an influence on the top speed, but this is not the only factor.
Top speed also has to do with things like your variator ring or petrol air tuning.
So, for example, when your scooter runs 60 km/h, it doesn't mean you can make it run 45 km/h again with just replacing the CDI. So always keep that in mind!

Assembly and return

It is also necessary to connect all the CDI cables, which are of course there for a reason. Otherwise, the CDI will most likely not receive a good power supply and will therefore not work.
In addition, all CDIs are new and are tested in the factory for functioning and are only shipped if they are fully functional. So it never happens that a faulty CDI is sent to you.

It is also the case that with some scooters, the ignition coil and CDI are combined in 1 part, so when these scooters stop working, it can be due to 2 parts. At the ignition coil or at the CDI, but because they are combined, both will no longer be able to do their job.

Attention!! CDIs cannot be returned because it is an electronic product. It is also the case when there is a short circuit in the scooter that this can immediately result in “inflating” the new CDI unit.
So always make sure you're sure which CDI you need! You can always call the assembly helpline for advice, so you can always be sure that you are ordering the right CDI.
