** These instructions are solely for the PAMCO Suzuki GS Ignition **
Applicable with: All Suzuki GS750 GS850 GS1000
Years: 1977 to 1981
Engine: 4-cylinder, 8-valve
Section A – Removing The Existing Points Plate
1. Remove the points plate and advance mechanism.
Section B – Rotor Installation
- Place the rotor on a flat surface.
- Place the PAMCO plate on the rotor.
- Hold the weights in the extended position and insert the tabs on the weights into the slots of the PAMCO rotor.
- The rotor can engage the tabs on the weights in one of two ways. This is the preferred way.
- With the trigger magnet positioned as shown above, one green wire goes to the coil for cylinders 1 and 4 (blue wire), and the other green wire goes to the coil for cylinders 2 and 3 (white wire). If you assemble the rotor with 2-3 in place of 1-4 as shown, then you can either do it again, or just reverse the colors for each cylinder.
- Install the PAMCO plate and rotor in place of the points plate with the upper mounting screw in the center of its slot, as shown.
Section C – Wiring Instructions
1. Connect the red wires from the PAMCO to the orange/white wire that comes from the kill switch. The orange/white wire is still connected to the coils as well. Suggestion: typically there is an orange/white going to each coil; make a pig tail with bullet connectors and use one of the orange/white wires to power both coils while using the other orange/white to connect to the red wires from the PAMCO.
2. The black wire from the PAMCO is connected to the frame.
3. One of the green wires is connected to the 1 – 4 coil (white wire).
4. The other green wire is connected to the 2 – 3 coil (black wire)
5. The engine should start at this point. If it does not, turn off the ignition switch and verify which set of cylinders is associated with which color wire per step 4, above.
6. You can rotate the crank with a wrench on the nut that secures the PAMCO rotor to position the timing marks for either 1-4 or 2-3 cylinders. Note the position of the trigger magnet (step 4, above).
7. After you have started the engine, use a timing light connected to cylinder #4 and look in the hole on the top of the plate to see where the timing is. If timing is not dead-on for both the base and advance marks (2500 RPM and above), use the advance mark for setting timing.
8. You can rotate the crank with a wrench on the nut that secures the PAMCO rotor to position the timing marks for either 1-4 or 2-3 cylinders. Note the position of the trigger magnet (step 4, above).
9. After you have started the engine, use a timing light connected to cylinder #4 and look in the hole on the top of the plate to see where the timing is.
10. Loosen the mounting screws for the plate and rotate it clockwise to retard the timing or counterclockwise to advance the timing.
11. Secure the mounting screws.
Your PAMCO Ignition is now installed.
