To enhance the reliability of a 1973 Triumph Bonneville 750, the following upgraded parts and services are recommended:
1. Electronic Ignition System: Replace the original points ignition with an electronic ignition system (e.g., Boyer or Pazon) for more reliable starting and consistent timing.
2. Upgraded Charging System: Install a modern alternator and solid-state voltage regulator/rectifier (e.g., Podtronics or Tympanium) to improve charging efficiency and reduce electrical issues.
3. Carburetor Upgrade or Rebuild: Rebuild or replace the original Amal carburetors with modern versions or Mikuni carbs for better fuel delivery and easier tuning.
4. Oil Filter Conversion Kit: Add an external oil filter system to improve oil filtration and engine longevity.
5. Improved Wiring Harness: Replace the original wiring harness with a new, high-quality one to prevent electrical failures.
6. Stainless Steel Fasteners: Use stainless steel nuts, bolts, and screws to reduce corrosion and maintenance.
7. Modern Tires and Tubes: Install modern tires for improved handling and safety.
8. Front Fork Rebuild: Rebuild the front forks with new seals and possibly progressive springs for better suspension performance.
9. Brake System Upgrade: Overhaul or upgrade the front disc brake and rear drum brake components for improved stopping power.
10. Upgraded Coil and Plug Wires: Use high-quality ignition coils and plug wires for stronger spark and reliability.
11. Primary Chain and Tensioner: Replace or inspect the primary chain and tensioner to prevent drivetrain issues.
12. Regular Valve Adjustment and Timing Checks: Perform routine maintenance for proper engine performance.
These upgrades help improve reliability while maintaining the bike’s classic character.
