Ignition System
Dyna Coils $80 each with mounting bracket, $140 pair (no mounts)
Dyna coils are available for any Airhead Boxer, providing 35000 volts of reliable ignition power. They can be used as a very cost-effectivereplacement for original coils which have a problem with cracking. By matching the correct coil, no control unit changes are necessary.
GREEN coils have 3 ohms primary resistance, for points ignition systems and older dual-plug applications.
BROWN coils have 1.5 ohms primary resistance,for '81 through '95 Airheads with factory electronic ignition.
$90 Each bracket and hardware included for use on all single-coil models from 1981 to 1995.
New Bosch Coils For 1970 Through 1980 Models : /5 , /6 , and /7, R90S $70 pair, 6 volt $85 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

Remanufactured Hall Sender Unit $175.00
1981 -95 models with factory electronic ignition. The factory does not provide individual repair parts for the ignition trigger, only complete assemblies - and they are not cheap. Done on an exchange basis , each unit is completely disassembled for thorough cleaning and lubrication of the spark advancer. Electrical components are replaced with new and the finished assembly is tested. Your part sent in will be repaired and the same one will be returned to you.

/2 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.
Plug Wires Red, Blue or Yellow $35.00 Basic Black $25.00
All wires come with 5k ohm NGK caps (as shown). Fit Airheads only.

Bosch Starter Renewal $75 plus shipping and handling
Starters are robust, but over time, the shaft bushings usually develop enough wear to cause internal drag or interference when it tries to turn . This requires too much current from the battery , and frequently there won't be enough left for the ignition system to work . Hard starting can frequently be directly attributed to excessive starter current draw . Starter service includes armature shaft and drive gear bushing replacement, commutator cleaning and truing, brush inspection, and overall cleaning and lubrication. If more serious problems are found, an exact quote will be provided before proceeding.
New 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.)
