Motorcycle left parked for a long time: what maintenance before restarting
Hello, it’s Patrick. To restart a motorcycle that has been sitting unused, first check the battery, fluids, fuel, tires, chain, and brakes; only turn the key after completing this safety check. A few simple checks can reduce the risk of breakdowns and unpleasant surprises on the road. Take your time and don’t force anything, especially if the engine won’t start.
What to do immediately:
- Inspect the motorcycle and look for leaks, damaged cables, and signs of corrosion.
- Check the motorcycle battery and recharge it with a suitable charger if necessary.
- Check the oil, coolant, and brake fluid levels.
- Inspect the motorcycle tires, then check their pressure according to the manufacturer’s recommendations.
- Test the controls, lights, and motorcycle brakes before your first ride.
To round out this motorcycle maintenance, also see this guide to motorcycles left in the garage and these tips on how to avoid a repair with the right checks.
Essential checks before restarting a motorcycle
After several months out of use, the battery may be discharged and the electrical contacts may be oxidized. Also check the terminals and fuses; if the battery won’t hold a charge, replace it rather than making repeated attempts to start the engine.
Inspect the engine oil and other fluids. An oil change is not always necessary after a period out of use, but it is required if the scheduled maintenance interval has passed, the oil looks contaminated, or the manufacturer’s manual recommends it.
| Component | Check | Action if there’s a problem |
|---|---|---|
| Battery | Charge and condition of the terminals | Recharge or replace |
| Fuel | Age and appearance | Replace if degraded |
| Tires | Pressure, cracks, deformation | Inflate or have them replaced |
| Brakes | Lever and pedal response | Do not ride before getting a diagnosis |
Fuel, tires, and chain: checks you shouldn’t put off
Old fuel can make starting difficult, especially if the motorcycle has been sitting unused for several months. If the gasoline smells bad or appears degraded, have it drained appropriately and fill the tank with fresh fuel; a motorcycle with a carburetor may need cleaning.
Check the tires when cold, following the values specified by the manufacturer. Cracks, deformation, or hardened rubber warrant a professional opinion. Also clean and lubricate the motorcycle chain, then check its tension according to the manual.
“A motorcycle that starts isn’t necessarily ready to ride.” It’s a useful reminder: the engine may be running while the tires or brakes are still unsafe.
Restarting a motorcycle: a simple three-step procedure
- Step 1: Place the motorcycle on a stable surface, check the fluid levels, and visually inspect the hoses, cables, and underside of the engine. Charge the battery if it is low.
- Step 2: Turn on the ignition and try to start the engine briefly, following the manufacturer’s procedure. Avoid repeated attempts or twisting the throttle unnecessarily.
- Step 3: Once the engine starts, let it run briefly and watch for warning lights, unusual noises, smoke, and leaks. Test the brakes and lights before setting off.
If the engine doesn’t start after a few attempts, stop: check the battery, fuel supply, and spark plugs rather than draining the battery. If the brake lever feels spongy or a leak appears, don’t ride; have the motorcycle inspected.
If the motorcycle has been sitting for a few weeks, a visual check and battery recharge may be enough, depending on its condition. If it has been out of use for several months, also check the fuel, chain, tires, and maintenance schedule specified by the manufacturer.
A rider found his motorcycle after it had spent the winter in the garage and wanted to ride straight to work. The rear tire was severely underinflated: a two-minute check saved him from a risky ride.
After starting the engine: safety checks before getting back on the road
Test the lights, turn signals, and horn, then check that the throttle and clutch return properly. Ride the first few yards slowly in a safe place to make sure the motorcycle brakes respond normally.
If unusual noises, persistent smoke, or a warning light appear, turn off the engine and find the cause before getting back on the road. A gradual restart helps you spot problems early that might go unnoticed while the motorcycle is stationary.
Practical questions before getting a motorcycle back on the road
Should you change the oil after several months without riding?
Not automatically. Check the scheduled service interval, the oil level, and its condition; change the oil if it is due, contaminated, or recommended by the manufacturer.
What should you do if the motorcycle won’t start after a long period out of use?
Avoid repeated attempts. Check the battery, fuses, fuel supply, and spark plugs; contact a professional if the problem persists.
Can you ride if the tires have lost pressure?
No, not before restoring the recommended pressure and inspecting the tires. Cracks, deformation, or significant wear require a professional inspection.
What should you check first on the brakes?
Test the firmness of the lever and pedal, look for leaks, and check that the wheels aren’t dragging. If the controls feel spongy or abnormal, don’t ride until the motorcycle has been repaired.
