Latest version of the proven BGM PRO HP (High Power) ignition base plate for the conversion from contact ignition to electronic ignition.
Suitable for e.g. Vespa VNA,VNB, VBA, VBB, GL, Super, Sprint, GT, GTR, TS
BENEFITS ELECTRONIC IGNITION
Specially developed for the conversion of contact controlled engines to
Maintenance-free electronic ignition.
After conversion, the former weak 6Volt on-board power supply system has a powerful 12Volt light output. The previously self-regulating electrical system is converted to a reliable and bulb-friendly regulator control (e.g. with BGM6690). The high-quality wiring ensures a safe transmission of the high light and ignition power. With its high wattage, it already provides a very good light output when idling, which does not diminish even when using the indicators or additional power consumers. Maintenance work, as usual with contact ignitions, is omitted.
ADVANTAGES BGM PRO HP V2.5
BGM has revised the thousandfold proven BGM Pro ignition base plate and made it even better.
Special attention was paid to a very high quality of the coils and the pickup.
In addition, the wiring was changed to textile-sheathed silicone cables.
A special gimmick is the cord already attached to the cable branch for easy insertion of the cable harness through the cable channel in the engine housing.
Also the base plate now has a degree exact scaling for easier adjustment.
Compared to a conventional electronic ignition the BGM Pro HP V2.5 ignition base plate has specially combined coil windings. This improves the efficiency of the alternator and offers with 120W a high light output. In contrast to a Vespa PX ignition base plate the BGM Pro HP has a longer and differently laid cable load to be able to mount the ignition base plate also on older vehicles perfectly. In addition it has an adapted base plate contour to fit perfectly on engines before 1977 (with a larger shaft seal seat than PX).
- High light output (120W) due to maximum number of windings
- Proven exciter coil with copper plate for highest reliability
- Pickup with carbon barrier layer for a clean ignition pulse
- Cleanly processed light coils
- High quality solder joints
- Original cable lugs and -length for very easy wiring
- Combinable with additional modules (PiFi, Kytronic,Agusto)
NOTE The BGM pickup has a nominal resistance of 100 Ohm (+/- 10Ohm)
BENEFITS SILICONE CONDUCTS
- Extreme temperature resistant (-40°C to +250°C))
- Always remains flexible
- Very good mechanical protection by the textile fabric
- Resistant to grease, Oils, alcohols, oxygen, ozone
- Very high insulating properties
CONVERSION TO ELECTRONIC IGNITION
When converting from contact ignition to this base plate, the use of a different fan wheel, a voltage regulator and a CDI is necessary.
A standard old voltage regulator, like the standard ignition coil, is no longer needed.
With the BGM voltage regulator BGM6690 a battery (12Volt battery required) can be charged while driving. The old wiring harness can still be used, but the formerly individual circuits must be combined here, because the voltage regulator only offers one output for the complete power supply. It is easier to convert to one of our conversion wiring harnesses (e.g. 9077011).
Everything necessary for this is available individually or as a set.
FIT FOR
The BGM ignition base plate fits all Vespa engines of the large frame models with rotary vane intake control, e.g.e.g. Vespa VNA, VNB, VBA, VBB, VLA, GT, GTR, Sprint, Rally, PX, LML 2T, Bajaj Chetak.
OTHER NECESSARY COMPONENTS
- pole wheel BGM Pro Electronic (BGM6661RT)
- CDI (9110018)
- voltage regulator (BGM6690)
- if necessary Cable harness (9077011)
- 12V Illuminant
Also as a set for conversion (BGM6661PRO)
BITTE BEACHTEN
The alignment of the crankshaft in the engine housing, and thus also the position of the pole wheel, is significantly more variable in the old large-frame engines (recognizable by crankshaft bearings of the same size with 25x62x12mm) than z.The crankshaft bearings are not fixed in the engine housing by a circlip, but are only fitted in the housing with a slight press fit. Due to various tolerances (e.g. the width of the shaft sealing rings, worn bearing seats, orientation of the cone on the crankshaft) there may be significant deviations from the originally intended positioning of the shaft in the crankcase. Prerequisite for a correctly working ignition is a perfect alignment of the pole wheel with the ignition base plate. Otherwise the trigger surface in the pole wheel will not run parallel to the pickup, which can lead to misfiring. If the ignition does not produce a spark, the fault is usually to be found here. For easy repair we offer distance plates (BGM8000S05) for the pickup on the ignition base plate. With this the correct distance can be restored in a simple way.
