CAUTION: CAREFULLY READ INSTRUCTIONS BEFORE PROCEEDING. NOT LEGAL FOR SALE
OR USE IN CALIFORNIA OR ON ANY POLLUTION CONTROLLED VEHICLES.
OVERVIEW
The Model 1005 ignition module can be used on
single cylinder Buell® Blast models with minor
modifications as described in this tech note.
REQUIRED PARTS
You will require the following parts:
1. Twin Tec Model 1005 ignition module P/N 1005
2. Twin Tec 3 ohm mini coil P/N MINI-COIL
2. The timing cover has a boss that must be relieved
to provide clearance for the Model 1005 ignition
module as shown in Figure 2. Final orientation of
the ignition module is shown in Figure 3. Remove
the minimum amount of material so that the ignition
module may be rotated freely from end-to-end of
the slots once the mounting standoffs are installed.
Caution: if you remove too much material, oil
leakage may occur.
Figure 2 – Timing Cover Modification
3. H-D timing rotor P/N 32402-83 or an equivalent
aftermarket part such as Twin Tec P/N ROTOR32402
4. VOES switch (highly recommended for all
applications except drag racing) such as Twin Tec
P/N VOES-KIT-MC7.
INSTALLATION
1. The timing rotor requires a modification as shown
in Figure 1 below. Flatten or grind off the existing
index notch. Punch a new index notch oriented 45
degrees counterclockwise from the original notch.

The Buell® Blast engine has a straight line as
the TDC timing mark. You can follow the same static
timing procedure as explained in the Model 1005
instructions. For precise timing or checking custom
advance curves, use a dial-back timing light referenced
back to the TDC timing mark. All standard dial-back
