Installing the PAMCO Suzuki GS750 GS850 GS1000 Ignition Section A Removing the Existing Points Plate 1. Remove the points plate and advance mechanism. 2. Remove the points cam from the advance mechanism. On some models of the advance mechanism, it is necessary to remove the weights as the points cam has a flange on the bottom. 3. Reinstall the weights if removed in step 2. Section B Pin Removal (on some models) Sometimes, there is a small pin located on the shaft of the advancer. If you have this pin on your advancer, follow these instructions for removal: b1. Check for the pin. If present, grind it off with a small rotary grinding tool or a file. If necessary, clean with WD-40 to remove metal particles, then apply a light coat of oil to prevent rust. b2. Apply a light coating of multipurpose grease to the advancer shaft. b3. Bolt the rotor to the advancer, checking for free movement and complete spring return.
Section C - Rotor Installation The PAMCO rotor is now installed on the advance mechanism with the PAMCO plate in between. Each advance weight must be extended to allow the slots in the PAMCO rotor to engage the small tabs on the weights. 1. Place the rotor on a flat surface.
2. Place the PAMCO ignition plate on the rotor.
3. Hold the weights in the extended position and insert the tabs on the weights into the slots on the PAMCO rotor.
4. The rotor can engage the tabs on the weights in one of two ways. This is the preferred way.
5. 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. 6. 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 D 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. Replace the cover and take a short ride to check for proper timing and operation throughout the rev range at operating temperature. Contact us if you have any questions or problems.
