INTERNAL ROTOR IGNITION MVT DIGITAL DIRECT WITH LIGHTING COIL PIAGGIO NRG / GILERA STALKER BEFORE 2003

WHAT IS MVT DIGITAL DIRECT?

The MVT Digital Direct ignition (“MVT DD”) is an internal rotor and digital ignition, that is to say that the ignition advance is modified according to the engine speed to offer the maximum performance (thanks to the CDI box). It is mainly intended in combination with a Racing or Hyper Racing engine of 70 cc and more.

The strong point of this MVT DD ignition is that it is equipped with a 12 Volts – 55 Watts output. So you will be able to keep your lighting while benefiting from increased performance, especially in terms of range of use and engine responsiveness.

HOW TO SET AND ADJUST THE MVT DD IGNITION?

• First of all, you will have to dismantle your original ignition and then carefully install your MVT Digital Direct ignition. Do not tighten the ignition stator and the ignition rotor until you have adjusted the timing.
• For the timing, take a timing pin or an ignition comparator and perform the timing as indicated in the manual: mostly 0.4 mm before TDC for a stock stroke and 0.35 mm for long strokes.
• You will then have to connect the ignition to your wiring harness in order to benefit from the lighting (see assembly instructions).

If you want even more performance, you can couple it with the MVT Eprom box to choose your ignition curve.

We recommend you to use a racing spark plug and a minimum carburetor of 19 mm.

PREREQUISITES

• • A timing pin to perform the ignition timing.
  • The presence of a charged 12 Volt battery is essential for the operation of the MVT ignition.
