The best electronic ignition
available for Airhead BMW models from 1970 to1995. The Wedgetail
ignition is the next evolution of the system, with all of the
sensitivities and limitations addressed. This is the ignition
system that finally suits the specific needs of our Airhead BMWs.

official North American importer, has to say about them; even

"The WEDGETAIL AUSTRALIA
IGNITION is available to fit all BMW Airhead models from 1969
to 1996. There are two versions, one replaces the points plate
and centrifugal advance unit for the 1969-1978 US models. The
second version replaces the bean-can ignition trigger, which includes
the Ignition Control Unit (Module) and module mount, as well as
the bean-can with o-ring and harness plugs. We replace the points-in-the-bean-can
version used on 1979 and 1980 models, (only requiring an additional
wiring harness extension for $39 extra) It just plugs in place
of the existing module and bean-can, a fifteen-minute install,
including ignition timing.
We offer the ICU Module in several versions: The most basic is
a single circuit for single plug ignition as a stock system replacement.
Then we offer an ICU Module with two identical, switchable ignition
circuits, one being a backup for the other, in case of on-road
failure. Both versions are also available with a different advance
curve map more suitable for Dual Plugged Airheads. So we have
Single Plug/Single Circuit, Single Plug/Dual Circuit, Dual Plug/Single
Circuit and Dual Plug Dual circuit. In addition, we offer the
beancan in two versions, with one or two HES triggers inside,
and switchable between them. We do not offer a dual-HES Points
replacement version at this time, because there is not adequate
space on the sensor mounting plate for the robust Hall Effect
Sensor that we use (it is NOT the failure-prone Honeywell sensor
that BMW uses in their cars and motorcycles.) We are working with
a supplier for a more compact sensor for that application, but
that is a ways off. All versions of the WEDGETAIL AUSTRALIA IGNITION
are compatible with all coils from 0.7 to 3.0 Ohms, including
the various aftermarket dual-output coils. The ICU senses coil
current and limits reverse current spikes, such as can occur when
the secondary spark wire is disconnected or fails.
These dual-circuit versions of the WEDGETAIL AUSTRALIA IGNITION
are intended for Round-The-World travelers and off-road riders
who venture far into the outback where repair parts might be difficult
or impossible to get in time to avoid larger issues. Remember
that these systems were developed by guys who ride into Australia's
Outback, where a failed ignition system could mean dying on the
side of the road between oases. Since we Americans carry cell
phones and are often on well-traveled highways, we also offer
the single-circuit/single HES trigger models for economy.
The real "Magic"
in the Wedgetail Australian Ignition is two-fold: First, we use
nothing but the very best-quality components throughout, in stark
contrast to every other electronic ignition systems offered for
Airheads, which have been offered with the lowest-quality/lowest
cost components resulting in an unacceptable failure rate and
unstable ignition behavior. Second, we use a multiple-step digital
advance curve that is programmed to follow the needs of the Airhead
engine including the characteristic flow variables of the chain-driven
camshaft and pushrod-operated valve system.
The WEDGETAIL AUSTRALIA IGNITION
software contained in the ICU Module also has other features,
like that it delivers longer coil driver current at below 800
RPM, to create a fat, robust spark for fast starting and very
stable idle in all fuel and temperature conditions. This is the
first feature that people notice when they start their Wedgetail-equipped
Airhead for the first time. is that it starts and idles well immediately,
with half or no choke required. Then they notice that the familiar
lagor RPM drop as the throttle is cracked open is gone, replaced
with smooth, healthy and stable off-idle and return-to-idle behavior.
Once underway, they notice that the characteristic 3100-3200-RPM
power dip and vibration has vanished. Power flow feels turbine-like,
all the way to a robust redline.
Those are the words of the
testers and early adopters, not advertising slogans. I tell
every person the same thing: Try it for yourself.
Then we back it with a two-year No Hassle Warranty. Report a problem,
and we will replace the affected parts or whole system. This is
why we only have one source of sales in North America currently.
This gives us the most responsive and informed team to launch

New Bosch Coils For 1970 Through 1980
Models : /5 , /6 , and /7, R90S 6 volt $159 pair
These are the high-energy Bosch coils
known for years as " Blue Coils" because of their distinctive
color. Now, they're just natural aluminum but still the great
replacement coil for tired, aging original coils that don't develop
the full spark energy they might have had 30 or more years ago.
Very often, installing a new set of these coils will restore easy
starting, smooth running, and greater economy than was normal
with the original coils . These coils are 6 volt, wired in series,
just like the original design specification, and they will fit
directly into the original coil clamps. These are the newest production
from Bosch's new factory in Brazil. Beware of "Blue Coils"
that show up on the 'net at a remarkably low price! There are
several knock-offs out there, clever copies visually but invariably
of poor quality

Brand - New, Genuine BMW Part. Fits
all R1100, 1150, and 850 four - valve models .
Replica Plug Wires for R90S,
all /5 and /6, $50.00 per Pair
These plug wires are no longer available
from BMW, but these are exact duplicates of the original wires
that came on the early Airheads,constructed with parts from the
original suppliers to BMW.They have the correct 1K ohm resistance
and the braided-cloth-covered length of fuel line for abraision
prevention.Ready to plug in at both ends and renew the performance
and looks of your classic!
Plug Wires $40 Pair (55' - '69 Boxers only)
Spark Plug Wires are frequently overlooked
as a cause of hard starting or poor performance. Bad spark plug
wires can damage magneto coils on vintage BMWs as well. These
wires are correct in appearance and in function and have 0 ohms
resistance to keep the mag coil cool.
Red, Blue or Yellow $35.00
Basic Black $25.00
All wires come with 5k ohm NGK caps
(as shown). Fit Airheads only.
K75 Plug Wire Set, all years/models $84.95
Same quality materials and correct coil
connector as on the 4 cylinder wire sets.Keep that K75 running
like an atomic clock.
for 4-Valve K100, K1100 $89.95/4
Fits 90-93 K1,K100RS and all years
These spark plug wires are made from
very good quality jacketed copper cable, with the correct 5K ohm
resistor in the NGK caps. The caps are correctly sized for a snug
fit on the 12mm sized K plugs made with the screw-on terminal
nut on the end. The coil ends are the correct brass barrel - end
type for the K100, and clip-on types for the center stud terminal
found in the K75 and K1100 coil sockets. Thick rubber boots at
the coil end keep moisture away from the connectors inside. The
air-gap coil connectors aren't cheap, or easy to find other than
expensive original BMW parts. By using the exact correct part,
easy fit and long service are assured. Why pay the exorbitant
factory price, when these wire sets can restore smooth running
and efficiency to an engine suffering with 23 year old plug wires?
Do you run your car plug wires for 20 - plus years? Didn't think
so but if you do, the car needs help too!

Fits all years of R850, R1100, and
R1150 4-Valve Twins
These top-quality replacement wires
are constructed from highest-quality components that are the same
as used by the original equipment manufacturer. The plug caps
are the CORRECT 90 degree bend, with grab areas for the removal
tool found in the tool kit. This pair of wires costs the same
as ONE wire does from BMW.

Bosch plugs are no more. Happily NGK
fills the gap with the proper plugs to keep your Airhead, F650
and K-Bike motoring along. NGK spark plugs are made to the same
level of quality, and incorporate all the same important design
features of the original Bosch part.
Ignition Module for ALL 1981through 1995 Airheads, $95.00 with
This is the same control unit now being sold by BMW as the
replacement for all previous versions. It incorporates a massive
heat sink to better deal with issues caused by over-heating. The
module is permanently riveted to the heat sink to insure clean
surfaces for proper heat transfer, so there is no recommended
maintenance as on the earlier designs.
The ignition control module now controls the dwell time independently
of the Hall sender,to improve the sometimes uneven startup and
cold idle,especially. This also helps maintain accuracy as the
old original parts in the Hall sender may wear.
The heavy-duty ignition control unit comes with a genuine BMW
mounting bracket for easy, bolt-on replacement. The original harness
connector plugs right in, just like stock.
Ignition Control Unit for Boxer $60.00
Ignition Control Unit-Used on all boxers
with factory electronic ignition, up to 1993. These are not from
the original equipment supplier, but they are very reliable and
work the same in every way. Oh, and more thing: they cost over
a hundred dollars LESS than the originals! Take the money you
save and ride a few more miles :)
Magneto Coil '55-'69 Airheads R51/3 through /2 Twins $160.00
Great replacement for the ever-aging
and failure - prone original magneto coils. Almost all of the
original coils are now failing routinely. A sure indication of
this progressive failure is hard starting when hot. As it gets
worse, there may soon be misfiring at high speeds as well. These
coils are of modern, improved design and manufacture for a perfect
fit and restored reliability. Made with an external ground wire
connection for increased reliability , and the high-tech resins
and plastics used in their construction means they should help
keep your bike around for the next 50 years. Make it right with
a new condensor, $8.
(It is strongly recommended that the
condensor should be replaced whenever a new coil is fitted . Old,
failing condensors can cause serious coil problems on even a new
part . These new ones come with the wire made on, so there's no
tedious soldering like the originals.)
Original BMW parts for long life.
