Understanding this starter’s design and maintenance needs is crucial for preserving the XJ700 Maxim’s reliability and performance.
 
Technical Specifications and Design
 
  1. Electrical System
    • Operates on a 12-volt DC power supply, drawing approximately 80–120 amps during engagement.
    • Compact design with a permanent magnet (PM) motor, weighing just 2–3 lbs (0.9–1.4 kg) for motorcycle-specific weight constraints.
  2. Mechanical Construction
    • Features a 9-tooth pinion gear that meshes with the engine’s flywheel ring gear.
    • Integral solenoid for direct engagement, eliminating the need for external relays.
    • Sealed housing to protect against moisture and road debris.
  3. Compatibility
    • Specifically designed for the 1986 XJ700 Maxim (model code XJ700S) with a 6-speed transmission.
    • Matches OEM part number 2E3-81800-00-00 or equivalent aftermarket specifications.
 
Starter Motor Operation and Placement
 
  • Positioning: Mounted on the left side of the engine, adjacent to the clutch housing.
  • Engagement Process:
    1. The rider activates the starter button, sending a low-current signal to the solenoid.
    2. The solenoid engages, connecting the battery to the starter motor and driving the pinion into the flywheel.
    3. The motor spins the crankshaft to the required RPM for ignition, then disengages automatically via an overrunning clutch.
 
Common Issues and Troubleshooting
 
Issue Possible Causes Solutions
No response when pressing the starter button Dead battery, blown fuse, faulty starter relay. Charge/replace battery, check fuses (15A main fuse), test relay.
Starter spins but engine doesn’t crank Worn pinion gear, damaged flywheel teeth, clutch slippage. Inspect starter drive and flywheel; replace worn components.
Grinding noise during startup Misalignment between pinion and flywheel, loose mounting bolts. Tighten bolts (torque: 8–10 ft-lbs), check for gear wear.
Starter overheats or smells burnt Prolonged cranking, internal winding short. Allow cooling; test windings with a multimeter; replace if faulty.
 
Replacement and Maintenance Guide
 
  1. Removal Steps
    • Disconnect the battery negative cable to prevent electrical shorts.
    • Remove the left side fairing and engine guard for access to the starter motor.
    • Unplug the solenoid wiring harness and detach the battery positive cable from the solenoid terminal.
    • Unscrew the two mounting bolts (10mm socket) and carefully remove the starter from the engine.
  2. Installation Tips
    • Clean the mounting surface and check for debris that may affect alignment.
    • Ensure the pinion gear aligns smoothly with the flywheel; no shims are typically needed for this model.
    • Torque mounting bolts to 8–10 ft-lbs and reconnect wires securely.
  3. Routine Maintenance
    • Clean battery terminals annually and check voltage (12.6V+ when rested).
    • Inspect starter wiring for fraying or corrosion, especially near the solenoid connections.
    • Lubricate the starter drive gear with lightweight grease every 10,000 miles to reduce wear.
 
Aftermarket vs. OEM Starters
 
  • OEM Starter: Offers precise fit and durability but may cost $150–$200.
  • Aftermarket Starters: Reputable brands (e.g., Denso, Hitachi) cost $80–$120, with similar performance if properly specified.
  • Remanufactured Units: Save 30–40% compared to new, but ensure they include a warranty (typically 1 year).
 
Tips for Cold Weather Starting
 
  • Battery Maintenance: Use a trickle charger in winter to maintain optimal voltage, as cold reduces battery efficiency.
  • Starter Protection: Limit cranking to 10-second intervals with 30-second breaks to prevent overheating.
  • Engine Preheating: Use an engine block heater (if installed) to reduce starter strain in freezing temperatures.
 
Conclusion
The starter motor for the 1986 Yamaha XJ700 Maxim is a critical component that requires attentive maintenance and timely replacement to ensure reliable starting. Its compact design and integrated solenoid make it well-suited for the motorcycle’s inline-four engine, but wear from regular use can lead to issues. By addressing common problems proactively and following proper installation practices, XJ700 Maxim owners can preserve their bike’s starting performance and enjoy consistent rides.
