EnDuraSpark Ignition System for Bosch 3-Phase Alternators !

New Electronic Crank-mounted Design ! 

If you have the EnDuraLast Charging System installed, see EDL-IGN

BMW R Airhead with Bosch 3-Phase Charging System

Completely replaces BMW Ignition / Canister 

Crank-mounted trigger eliminates

• Electronic ignition module with digital technology mounts remotely
• Ignition Module electronics resin encapsulated & protected in sealed box

·         Two spark advance curves

o    BMW  - single spark plug

• Low profile light sensor fits under alternator cover with no cover modifications (usually - some mod may be required on some models to allow alternator cover to clear the crank trigger)
  
• Crank mounted trigger by-passes worn ignition canisters and timing chains
• More accurate for efficient timing, performance and fuel mileage
• Eliminates points and mechanical advance (1970-1980)
• Compatible with original Bosch oil-filled ignition coils ( x 2 coil setup) or aftermarket (Dyna, etc)  
  • Optimal ignition coil resistance 2.0-3.0 ohms  
  • Bosch Super Coil, 6v x 2 (Part #BO-Coil6Vx2)
    
  • Dyna  coils compatible - check resistance value 
    • Bosch x 1 dual tower coil set up will not work - 1.25 ohms
• Bolts right on and wires up easily – illustrated Instruction Guidelines included
• Designed & manufactured to premium quality specifications for reliability and durability

Electronic Ignition Kit  for BMW R Airhead with original Bosch Alternator, includes -

   - Electronic module, light optical sensor

Kit also comes with -

• Crank mounted aluminum disc trigger
• Wiring and mounting hardware
• Installation guidelines

Ignition coils not included
Recommendations for Coils

This EnDuraSpark Electronic Ignition kit is designed for 1970-1980 BMW points–based ignition motorcycles with Bosch 3-Phase Charging Systems.

This kit is designed for both stock single-plugged engines and engines which have been modified to add a second spark plug to each cylinder, “dual-plugged” engines. 

The kit can be used on BMW Airheads with exposed points under the front engine cover:

·         All /5s (1969-1973 R50/5, R60/5 and R75/5) 

·         All /6s (1973-1976 R60/6, R75/6, R90/6 and R90S)

·         Some /7s (all R60/7, all R75/7, R80/7 and R100/7 up to 1978)

·         R100S, R100T, R100RS, R100RT up to 1978

and  BMW 1979-1980 Airheads with points in the "bean can":

·         1979 R100S,

·         1979-1980 R80/7, R100S, R100T, R100RS, R100RT

·          All R45, R65  up to 1980

·          1980 R80G/S, R100, R100CS

   Component Compatibility

   Spark Plug Compatibility

The EnDuraSpark Electronic ignition should be used with stock spark plugs, stock ignition wires, and stock ignition caps.  For spark plugs, this means non-resistor plugs.  Bosch has phased out their original non-resistor W5DC, W6DC and W7DC spark plugs and replaced them with WR5DC, WR6DC and WR7DC plugs, respectively.  These are resistor plugs not compatible for this application.  Currently, Bosch non-resistor spark plugs can only be purchased at BMW motorcycle dealers. 

   Spark Plug Cap Compatibility

The EnDuraSpark Electronic ignition is compatible with the OEM stock 1K Bosch, 1.2K Beru, and 5K Bosch spark plug caps that originally came on the motorcycle.  It is also compatible with any 1K or 5K aftermarket spark plug caps such as the NGK LB01FP, LB05FP or LB05EP.

   Ignition Wire Compatibility

The EnDuraSpark Electronic ignition is compatible with the OEM stock ignition wires that were originally outfitted on BMW Airheads.  These are Hypalon covered, stranded copper core, non-resistor ignition wires with a resistance of about 2 ohms per foot.  The ignition is also compatible with Hypalon or silicon insulated stranded copper aftermarket wires, such as that manufactured by Accel, Belden, and Packard. 

It is important that copper core wires are used, not the carbon powder center ones normally sold at auto parts stores. 

   Coil Compatibility

The EnDuraSpark Electronic ignition is compatible with all stock BMW ignition coils used on models using points and condensers.  Specifically, the EnDuraSpark can be used with ignition coils that have a primary resistance seen by the electronics between 2 -3 ohms.  Since both stock Airheads and dual-plugged Airheads use two coils wired in series, each of these coils needs a primary resistance of 1 to 1.5 ohms.

The EME ignition is NOT compatible with conventional electronic ignition coils, which typically have a primary resistance of around .7 ohms.  These coils will fry the EnDuraSpark ignition.  The older black Bosch coils and the newer electronic black Bosch coils look almost the same – except the electronic ignition coils (which can’t be used) have a small yellow lightning icon on them.

The optimal  replacement coils available for use with the  EnDuraSpark Electronic Ignition are the Bosch 6V 1.5 ohm “Super” coils, part # BO-Coil/6Vx2 available from Euro MotoElectrics.
