Preparing to Start
Getting ready to start an old Harley Davidson involves a few essential steps. Ensuring that you have everything in place can make the process smoother and increase your chances of success.
Gathering Necessary Tools
- Wrench Set: A metric and standard wrench set helps with various bolts and nuts.
- Socket Set: Provides additional leverage and ease for tight spaces.
- Screwdriver Set: Both flathead and Phillips screwdrivers are crucial for different tasks.
- Multimeter: A multimeter checks the electrical system and helps identify battery issues.
- Oil Can: Essential for lubricating parts that may have dried out.
- Fuel Stabilizer: Aids in treating stale fuel if found in the tank.
- Shop Manual: Referring to a specific manual for your model ensures accurate information.
- Inspect Fuel: Remove the fuel cap and visually check for clarity. Stale fuel often appears dark and has a sour smell. If the fuel looks bad, drain it completely and replace it with fresh fuel.
- Check Oil Level: Locate the oil dipstick or sight glass, and verify the oil is at the appropriate mark. Old oil may require a complete change, especially if it appears dark or thick.
- Add Essential Fluids: If levels are low, fill the fuel tank with fresh gasoline and top off the oil with the correct type specified in your manual.
Completing these preparations ensures you’re ready to start your vintage ride efficiently.
Starting the Engine
Starting an old Harley Davidson requires attention and care to ensure a successful ignition. Following a methodical approach can help you get your vintage bike running smoothly.
Initial Steps for Starting
- Check Fuel: Inspect the fuel tank for clarity. Stale or contaminated fuel can prevent ignition. If necessary, drain the old fuel and replace it with fresh gasoline.
- Inspect the Battery: Verify the battery’s charge. Connect a battery charger if it’s low. Clean any corrosion from the terminals to ensure a good connection.
- Adjust the Choke: Set the choke to the closed position. This action enriches the fuel mixture, making it easier for the engine to start.
- Turn on the Ignition: Flip the ignition switch to the “on” position. Listen for a click indicating that the electrical system is active.
- Kickstart or Press Start: Depending on your model, either kickstart the motorcycle or press the start button. Apply gradual pressure, allowing the engine to turn over.
- Monitor Engine Sounds: Once the engine starts, pay attention to any unusual sounds. A smooth purr indicates a healthy engine, while sputters could signal issues needing troubleshooting.
- Engine Won’t Start:
- Dead Battery: Charge or replace the battery. If connections are loose, tighten them.
- Fuel Issues: Ensure fresh fuel is in the tank. If the bike is equipped with a petcock, make sure it’s set to the “on” position.
- Backfiring:
- Lean Fuel Mixture: Adjust the carburetor to enrich the fuel mixture. This provides the right balance for ignition.
- Timing Issues: Check the ignition timing. Misalignment can cause backfiring.
- Engine Turns Over Slowly:
- Weak Battery: Charge or replace the battery if it struggles to crank the engine.
- Dirty Starter: Clean the starter motor, as accumulated grime can impede performance.
- Fuel Leak:
- Inspect Hoses: Check all fuel lines for cracks or disconnections. Replace damaged hoses promptly to avoid hazardous situations.
- Carburetor Seals: Ensure that the carburetor is tight and the seals are intact, preventing fuel from leaking.
By following these steps and tips, starting your old Harley Davidson becomes an easier and more enjoyable task.
Maintenance Tips for Longevity
Maintaining an old Harley Davidson ensures it stays in optimal condition. Focus on regular upkeep to enhance its lifespan and performance.
