How To: Install The XSCharge XS650 Standard Ignition


The XSCharge Standard Ignition System (200-2900) is a direct replacement for the points plate and points cam system on a Yamaha XS650. It can also be installed in later models of the XS650 that have a factory TCI system by installing the complete mechanical advance mechanism. The system requires the use of a dual output coil (similar to the MikesXS coils 17-6903 or 17-6822).


• Technology:  Hall effect sensor, IGBT coil driver
• Dwell:  Fixed, 60 degrees
• Coil Primary Resistance:  2 to 3 Ohms, dual output.
• Operating Voltage:  6 to 18 VDC
• Operating Current:  13 ma
• Operating Temperature:   -40 to +150C (-40 to 302F)
• Spark Advance:  Standard, centrifugal

Please Note:

  • The stock coil in the TCI-equipped models may be retained when installing this system.
  • It is recommended that the advance rod and centrifugal unit be serviced prior to installing this system.
  • Installation on a 1980 to 1984 Yamaha XS650 requires the installation of the
    centrifugal advance system and cam bushings. Those kits can be found here.


1. Do not apply power until the installation is complete.

2. Do not apply power unless both spark plugs are

3. Do not test for spark with one or both plugs

4. Do not disconnect the battery with the engine running.

5. Ensure that the battery cable connections are secure.

6. Do not leave the ignition on when the engine is not

**Failure to follow these cautions may damage the system and render it inoperative.**



1. Remove the gas tank.

2. Remove the two ignition coils and condensers on a ‘71 – ‘79 model.

3. Disconnect the plug from the TCI on an ’80 –  ’84 model.

4. Install MikesXS coil or use the stock coil on ’80 –  ’83 models.

5. Connect the Red/White wire from the wiring harness (switched battery) to either terminal on the coil.

6. Remove the points cam, points plate, points, condenser, and wiring.

7. Install the ignition replacement plate with the two mounting screws.

8. Route the wiring harness from the replacement plate to the coil.

9. Connect the wires from the harness as follows:

  • Red wire to battery connection on coil or to other Red / White wire
  • Green wire to the other coil terminal (no other wires should be connected to the green wire terminal)
  • Black wire to a good frame ground.

Note: You must ground the black wire to a good frame ground. The ground on the plate is not reliable while setting the timing.

10. Install the “rotor” on the advance rod shaft.

11. Install the large washer and nut with the lock washer.

12. Hold the rotor firmly to the right (clockwise) when tightening the nut on the shaft.

13. Hold the nut on the advance mechanism firmly when tightening the nut on the rotor.

14. Remove the access cover to the alternator.


Reinstall the gas tank and proceed as follows to set the timing. A strobe-type timing light is required.


Timing Instructions


1. Loosen the mounting screws on the plate.

2. Rotate the plate to position the mounting screws at the midpoint of the upper slot.

3. Tighten the upper mounting screw.

4. Connect the timing light. With a dual output coil, some timing lights may be erratic due to the fact that there are opposite “polarities” in the plug wires. If the timing light is erratic, then clip on to the opposite plug.

5. Start the engine and immediately shine the beam on the timing mark on the alternator rotor.

6. The strobe should illuminate the timing mark when it is between the two marks labeled “F”.

7. If necessary, loosen the mounting screws on the plate and rotate the plate clockwise to advance the timing and counter-clockwise to retard the timing.

8. Tighten both mounting screws, securing the plate.
