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. 

Kick Start Capability 

The Model 1005 is primarily intended for electric start applications. However, Rev 7.0 units (manufactured after January, 2006) can be programmed for kick start mode by using our PC Link Evo software and optional USB interface. If you order on-line, you can add a note stating that you require kick start capability and we will program the unit for you at no extra cost.  When programmed for kick start mode, the unit has zero cranking delay and a 30 second timeout before coil current shutoff. 

Sportster^® 1200S with Dual Plug Heads 

The Sportster^®1200S model with dual plug heads comes with a special ignition module, similar to that used on Twin-Cam 88^® models. If you require a programmable aftermarket ignition for the 1200S, we have the solution. You can use our Model 1005 EX version (not the 1005S). The Model 1005 mounts in the nose cone. The original equipment coil has low resistance primary windings that are not compatible with the Model 1005. You must replace the original equipment coil with an aftermarket four tower coil, such as the Dyna DC6-4, that has 3 ohm primary resistance. Please refer to our Dual Spark Plug Tech Note for more details. You will have to remove the original equipment MAP sensor. You will also require our timing rotor (P/N ROTOR-32402) and VOES switch (P/N VOES-KIT-MC7).   

Buell^® Blast 

If you require a programmable aftermarket ignition for racing the Buell^® Blast, we have the solution. You can use our Model 1005 Race version that mounts in the nose cone in place of the Blast  module. You must replace the original equipment coil with our mini coil (P/N MINI-COIL) that has 3 ohm primary resistance. You will also require our timing rotor (P/N ROTOR-32402) and VOES switch (P/N VOES-KIT-MC7). Minor modifications are required to re-index the timing rotor and provide clearance in the Blast timing cover. Please refer to our Buell^® Blast Tech Note for more details. 

Model 1005T - Special Version with Stage RPM Limiter for Drag Racing 

The Model 1005T is a special version with a stage RPM limiter intended for drag racing applications.  The purple/white wire normally used for the VOES connection is used to select between the stage and maximum RPM limit. The stage RPM limit is set by means of the two rotary switches on the module. The maximum RPM limit is programmed by means of the optional USB interface (P/N USB-INTF) and PC Link Evo software. When the purple/white wire is grounded by means of a switch, the stage RPM limit is selected, otherwise the maximum RPM limit is selected. Please refer to the Model 1005 Two Stage Tech Note for details.

3005-IH - Special Kit for 1999-2003 American IronHorse^® Motorcycles 

American IronHorse^â motorcycles manufactured through 2003 used a non-adjustable camshaft sensor based ignition system manufactured in England by Gill. Twin Tec now offers the Model 1005-IH version of our proven internal ignition can be easily retrofit to 2003 and earlier American IronHorse^â models. The Model 1005-IH has a special tach output that will correctly drive the American IronHorse instrument cluster. Note: for 2004-2005 American IronHorse^â models with crankshaft position sensor, we recommend our TC88A-IH system. The P/N 3005-IH Kit includes the special Model 1005-IH ignition, timing rotor, VOES switch, two 3 ohm mini-coils that must be used to replace the existing low resistance Gill coils, and all required electrical terminals. Please refer to the Model 1005-IH Installation Instructions for details.

The Model 1005 is a race proven product adaptable to a variety of applications. Chris Sansevere of Holeshot Cycles (Stuart, Florida) uses the Model 1005T with two stage RPM limiter on his 1998 Buell^® S2 shown below running an 11.80 ET in the ET Class at the recent High Stakes Shootout in Las Vegas.
