About CDI's

Let's walk briefly through the topic of CDI. Why should you replace a CDI?
There may be a number of reasons for this:

- Your scooter suddenly stops in the middle of a ride and won't start afterwards. (electric starter does nothing.)
- Your scooter won't start anymore.
- You want to return your scooter or, on the contrary, step up.

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

A CDI does not affect the top speed of the scooter with a two-stroke.
A CDI does affect the top speed of the scooter with a four-stroke.

In a four-stroke case, a CDI does affect the top speed, but this is not the only factor.
The top speed also has to do with things like your variator ring or petrol air adjustment.
So, for example, when your scooter is running 60 km/h, it doesn't mean you can run it 45 km/h again with just replacing the CDI. So always take that into account!

Sending assembly and return

It is also necessary to connect all the cables of the CDI, of course these are not for nothing. Otherwise, the CDI will most likely not receive proper nutrition and therefore will not work.
All CDIs are also new and are tested at the factory for functioning and will only be 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 into 1 part, when these scooters stop, this may be up to 2 parts. On the ignition coil or CDI, but because they are combined, both of them will no longer be able to do their job.

Please note!! CDIs cannot be returned because it is an electronic product. It is also true when there is a short circuit in the scooter, that this can immediately result in the 'blowing up' of the new CDI unit.
So always make sure which CDI you need! You can always call the assembly guide for advice, so you can always be sure that you order the right CDI.
