The Model 1005 internal ignition unit is triggered from the stock timing rotor at the end of the camshaft and mounted within the "nose cone" of the engine. This "nose cone" ignition is applicable to a wide range of H-D® engines. The Model 1005 ignition replaces all the H-D® OE ignition components including the bulky wiring harness and external module. The resulting clean appearance is especially desirable on custom motorcycles. The 50 states street legal Model 1005 EX version fits all 1970-1984 Shovelhead® Big-Twin® engines, 1986-93 883 XLH Sportster® engines, 1986-87 1100 XLH Sportster® engines, and 1984-1999 1340 Evolution® Big-Twin® engines and features advance curves suitable for all street applications including high compression engines. The Model 1005 Race version fits all 1970-1984 Shovelhead® Big-Twin® engines, 1971-1997 Sportster® engines, and 1984-1999 Evolution® Big-Twin® engines and includes race advance curves with a slightly wider adjustment range. The 50 states street legal Model 1005S EX fits 1998-2003 Sportster® engines (except dual plug 1200S) and directly plugs into the OE wiring harness (these late models came with an OE internal ignition). The Model 1005S EX has advance curves optimized for these Sportster® applications.
The Model 1005 is constructed with a low profile machined billet aluminum housing. Four rotary switches are used to set the operating modes (such as single or dual fire, advance curve family, and multi-spark), adjust the timing advance, and select the RPM limit. Two diagnostic LEDs indicate status and the state of the vacuum switch (VOES). The status LED is also used for static timing, as it will flash when the engine reaches top dead center (TDC).
You can adjust the slope of the advance curve. The user can optimize the timing advance for a wide range of applications - from stock to highly modified engines. For details, including advance curves, you can download the installation instructions from our website.
Switch selectable single or dual fire mode allows you to initially install the unit and run it in dual fire mode with your stock coil. You can then easily upgrade to single fire by adding an appropriate coil. If you have a tach, it will continue to operate properly (some competitive systems require that you purchase a tach adapter).
A special feature allows use of the tachometer wire for a link to a laptop PC when the engine is not running. While the customer does not require the PC link for any normal setup or operation, it can be used to access additional features for precise dyno tuning (such as programming a custom advance curve and setting rear cylinder timing offset). Our new USB interface (P/N USB-INTF) is used for this purpose. The USB interface is sold separately, but Windows compatible software is available for download. The software will operate in demo mode without an ignition attached.
