Preparation Before Starting
Before starting your 1972 BMW motorcycle 75/5, ensure it’s ready for a smooth ignition. Follow these steps to prepare.
Check the Fuel System
Check the fuel system for proper function. Inspect the fuel tank for old or stale gasoline; replace it with fresh fuel if necessary. Examine the fuel lines and connectors for cracks or leaks. Make sure the petcock is in the “on” position to allow fuel flow to the carburetors.
Inspect the Battery and Electrical Components
Inspect the battery and electrical components carefully. Ensure the battery terminals are clean and tight. Test the battery voltage using a multimeter; it should read around 12.6 volts when fully charged. Check the fuses and wiring for any signs of wear or damage, addressing any issues before starting the motorcycle.
Examine the Oil Levels
Examine the oil levels to ensure proper lubrication. Locate the oil dipstick or sight glass; remove the dipstick and wipe it clean, then reinsert it to check the level. The oil should be between the minimum and maximum marks. If the oil level is low, add the recommended oil to avoid engine damage.

Starting your 1972 BMW 75/5 can be a rewarding experience with the right steps. Follow this guide to get your vintage motorcycle running smoothly.
Step-by-Step Starting Procedure
- Check Fuel Levels: Ensure the fuel tank contains fresh gasoline. Drain old fuel if it’s been sitting for an extended period.
- Set the Petcock: Position the petcock to the “on” setting. This allows fuel to flow to the carburetors.
- Inspect the Battery: Confirm the battery is charged and terminals are clean. If the voltage is low, consider charging or replacing the battery.
- Engage the Kill Switch: Make sure the kill switch is in the “run” position, allowing the engine to start.
- Kickstart the Engine: With the bike in neutral, hold the clutch lever in and use the kickstarter to crank the engine.
- Listen for Sounds: Pay attention to engine sounds. A healthy engine produces a smooth start without unusual noises.
- Warm-Up the Engine: Let the motorcycle idle for a few minutes to warm up. This helps oil circulate and prepares the engine for riding.
Troubleshooting Common Starting Issues
- No Electrical Response: If pressing the starter results in no response, check the battery connection and ensure the battery is charged.
- Fuel Issues: If the engine cranks but doesn’t start, ensure fuel is reaching the carburetors. Inspect for clogged fuel lines or a malfunctioning petcock.
- Starter Problems: If the engine cranks slowly, look at the starter motor and connections. A faulty starter can impede the starting process.
- Electrical Components: If the lights are dim or flickering, check the battery voltage and wiring connections. Poor connections can disrupt electrical flow.
- Engine Flooding: In cases where the engine cranks but won’t start, it might be flooded. Allow the bike to sit for several minutes before attempting to start again.
By following these steps and troubleshooting tips, you can enjoy the thrill of starting your classic BMW motorcycle with confidence.
