Smart-Fire Vincent V-Twin 12 Volt

High-performance, ignition system for Vincent 50° V-Twin motorcycles with 12 volt electrics, positive or negative earth.  Optimised for high spark energy and low power consumption.

SMART-FIRE completely replaces the original Lucas/BTH magneto.
The result is improved performance, excellent starting, improved idling, smoother running and low maintenance.

System comprises:

• magneto replacement body incorporating precision engineered steel timing disc & digital trigger unit with static timing light
• digital Ignition module with mapped advance curve to suit the Vincent engine, user-programmable rev-limiter (set at the push of a button)
• miniature high-energy ignition coil
• ht leads with pre-fitted connectors & rubber ht covers
• plug caps
• fixing bolts/washers/nuts for ignition module & coil
• quality crimp connectors & insulators
• earthing wire (for positive earth electrics)
• full colour 16 page installation booklet

Magneto replacement housing consists of sand-cast alloy body with spun alloy cap, steel shaft, fully supported on two large ball-bearings & garter seal.  It uses the original drive gear or sprocket and requires no modifications to the engine.  Please note: this system is not self-energising. This system does not include battery or drive gear.

System developed in conjunction with technical engineer, Kirby Rowbotham.
The advance curve developed with technical assistance from the highly regarded Vincent authority, Bob Dunn

I just received and installed the Pazon ignition kit for my Vincent today and I am hugely impressed. Good stuff. I haven't yet had the bike out for a full on evaluation but so far it is a major improvement. I have to say that setting the timing was the easiest thing ever, but you already know that! I have attached a couple of photos of my 1950 Vincent Series C Rapide.   The bike is fully 12 volt converted and I was running a Lucas breakerless ignition which I have just replaced with the Pazon unit. The entire ignition system is fitted inside the magneto cover on the front of the engine. It has a V3 clutch, Shadow brakes, and high compression pistons.   I have also ordered a 1200cc top end conversion from Terry Prince as the bike is due for a cosmetic tidy up anyway.

Is your current ignition limiting your engine performance?

The Smart-Fire ignition incorporates a mapped advance curve that precisely controls the ignition timing throughout the rev range.
The active dwell control maintains the right energy in the ignition coil for optimum performance, whatever the engine rpm.
Whereas magnetos can give varying ignition between cylinders, the Smart-Fire ignition module's intelligent software maintains consistent spark energy to both cylinders.

Have you found setting the timing with other ignition systems a bit 'hit and miss'?

Timing made easy, with the on-board static timing light.
Simply set the rear piston to TDC, then position the trigger unit with the aid of the static timing light.  The process is explained with step-by-step colour photos in the supplied booklet.
Once set, the timing will automatically fire fully retarded at cranking speeds, then quickly reaches a full advance point suited to modern fuel.  Also, the timing won't ever go out of adjustment.

Concerned about damage to the electric start mechanism?

The Smart-Fire system will stay on time as low as 7 volts, so is ideal for electric starter models that can suffer from volt drops when cranking.

Poor dynamo charging system?  Concerned about ignition's drain on the battery?

The Smart-Fire system draws less than 7 watts at tick-over.
Pazon's design incorporates a miniature resin encapsulated ignition coil.
This low inductance coil is energised for a very short period of time, meaning low power consumption.

Worried about over-revving your engine?

The Smart-Fire has a built-in rev-limiter.
At the push of a button you can set the rev-limiter to limit the engine speed from 3000 rpm upwards.  Can be reset just as easily at any time.
