Welcome to the PAMCO CB350 Installation Guide for the New E-Advancer
Notes: 1.The E-Advancer should be mounted away from the engine and the ignition coils. Under the seat behind the gas tank is an ideal place.
2. Use either resistor spark plugs or 5K resistor spark plug caps
3. Coils must be stock 4.0 to 5.0 Ohms or equivalent.
Step1: Remove the gas tank.
Step2: Remove the points cover, points plate and advancer.
Step3: Disconnect the points wires that go to the coils.
Step4: Disconnect and remove the condenser(s).
Step5: Install the PAMCO plate as shown
Step6: Connect the wires from the PAMCO ignition plate as follows:
6a. Thread both cables through the slot where the points wires were.
6b. Connect both red wires from the sensors to the red wire from the E-Advancer sensor side four conductor cable.
6c. Connect the green wire from the lower sensor to the green wire from the E-Advancer sensor side four conductor cable.
6d. Connect the green wire from the upper sensor to the white wire from the sensor side cable of the E-Advancer.
6e. Connect both black wires from the sensors to the black wire in the four conductor cable on the sensor side of the E-Advancer.
Step7: Connect the wires from the coil side of the E-Advancer as follows:
7a. Connect the red wire from the cable on the coil side of the E-Advancer to the switched battery terminal of one of the coils.
7b. Connect the black wire from the cable on the coil side of the E-Advancer to frame or engine ground. This must be a good ground directly to the engine or frame, not from another ground wire.
7c. Connect the green wire from the four conductor cable on the coil side of the E-Advancer to the negative terminal of the left side coil. The negative terminal is the one that used to go to the points and is opposite to the switched battery terminal coil terminal.
7d. Connect the white wire on the coil side cable of the E-Advancer to the negative terminal of the right side coil.
Step8. Install the rotor. Rotate the rotor to engage the locating pin on the cam shaft .
Step9. Secure the rotor with the original washer and bolt.
Step10. Connect the timing light to the left side spark plug.
Step11. Remove the cover from the alternator below the points housing on the left side.
Step12. The engine should start now. If it does not start normally, check the installation and wiring.
Step13. Observe the timing mark on the alternator rotor even as you are starting the engine.
Note: The E-Advancer starts to advance at 1,300 RPM whereas the stock mechanical advancer does not start until 2,000 RPM. For this reason, set the idle to 1,000 RPM while setting the timing to ensure that you will obtain full advance.
Step14. If the timing mark is not at the firing point mark on the alternator rotor, loosen the hold down screws on the PAMCO plate and rotate the plate clockwise to advance the timing or counterclockwise to retard the timing.
Note: The individual PC boards for the left and right side sensors may be adjusted individually to obtain the ideal timing relationship between the two cylinders.
If necessary, loosen the two mounting screws on the RIGHT cylinder PC board first and move the board as necessary to obtain the desired timing for the right cylinder. If further adjustment is still necessary, loosen the two screws on the left cylinder PC board and move the board as necessary to obtain the desired timing. Then re-set the overall timing by rotating the plate as in step 14, and re-check the timing for both cylinders.
Step15. Increase the engine speed to 3,000 RPM and observe that the timing mark moves to the full advance position.
Step16. Tighten the hold down screws on the PAMCO plate, replace the covers on the points housing and alternator.
Under normal circumstances, you should not have to adjust or reset the timing. However, after the initial installation, you should check the timing after a few hundred miles.
tip: Both the left and right PC boards are adjustable. The instructions say to
move the plate for the left side, and that's fine if you can get the desired
results, but in some cases you have to move both of the PC boards and not worry
about where the plate ends up.
The other thing to consider is that you have to be at or below the idle speed in order to obtain full advance. If the idle speed is a little high, then some of the available advance will be used at idle leaving not enough for full advance. The tach on the bike may not be accurate enough to set the idle speed for timing, so do it in reverse. Set the timing for full advance and then set the idle speed to coincide with timing at the "F" marks.
