INTERNAL ROTOR IGNITION MVT DIGITAL DIRECT AM6 AFTER 2003 (12-PIN, WITH BATTERY)

INTERNAL ROTOR IGNITION WITH LIGHT

MVT Digital Direct 21 Inner Rotor Ignition with light for Minarelli AM6 engines (Yamaha, Peugeot, Beta, Rieju, Sherco, Fantic, ...etc.).

MVT DIGITAL DIRECT - TOP PERFORMANCE PLUS LIGHT

The MVT Digital Direct (short "MVT DD") is a digital internal rotor ignition with variable ignition timing, i.e. the ignition timing changes via the CDI depending on the engine speed to offer maximum power at any given time. It is primarily intended for use with racing or high-end setups of 70cc and more.

The main advantage of the MVT DD ignition is that it comes with a 12-volt 55-watt output. Unlike with many other internal rotor ignitions, you can retain lighting and on-board electronics with this ignition. Performance is noticeably improved, especially in terms of power band and responsivity.

• Power: 60W
• Ignition voltage: 42kV
• Max. Speed: 22,000rpm

ADJUSTING AND CALIBRATING THE MVT DD IGNITION

• First remove the original ignition and properly install the MVT Digital Direct ignition. Do not tighten the stator and rotor until the ignition has been adjusted.
• Using a micrometer or a TDC dial indicator, set the following parameters: for original stroke 0.4 mm before TDC, for long stroke 0.35 mm.
• Then connect the ignition to the wiring harness so that the vehicle lighting works (see assembly instructions).

If you need even more power, you can combine the ignition with the MVT Eprom Box to select an appropriate ignition curve.

We recommend to use a racing spark plug and a carburetor with at least 19 mm diameter.

• • A micrometer for precise ignition adjustment
  • A charged 12 volt battery is essential for MVT ignition operation. We recommend the 12V - 5Ah SLA4L-BS SLA battery.

This version of the Digital Direct is used on models with 12-pin stator (with battery). The MVT Digital Direct ignition for 6-pin stators (without battery) for Minarelli AM6 can be found under part number MVT-DD12.

Intended for 50cc motorcycles with Minarelli AM6 engine after 2003.
On Yamaha TZR, MBK X-Power, Rieju RS3, ...etc. the electric starter cannot be used with this ignition.
