Before starting a motorcycle engine after storage, it's important to perform a few checks to ensure the bike is in good condition. Here are some key things to consider:
Visual Inspection: Look for any signs of damage or wear on the motorcycle, including the frame, bodywork, tires, and cables. Check for leaks, loose connections, or any parts that may have deteriorated during storage.
Battery: Check the battery's charge level. If it was disconnected during storage, make sure to reconnect it securely. If the battery is low or dead, charge it using an appropriate charger or consider replacing it if necessary.
Fuel System: If the motorcycle was stored with fuel in the tank, check for any signs of deterioration, such as a foul odor or varnish-like deposits. If the fuel appears contaminated, it's advisable to drain and replace it with fresh fuel. Additionally, inspect the fuel lines and filters for any blockages or damage.
Oil and Fluids: Check the engine oil level and quality. If the oil appears dirty or has been in use for an extended period, it's recommended to change it. Also, inspect the coolant, brake fluid, and any other fluids to ensure they are at the appropriate levels and free from contamination.
Tires and Brakes: Examine the tires for cracks, bulges, or flat spots caused by prolonged storage. Ensure the tire pressure is at the recommended level. Inspect the brake pads and discs for wear and check the brake fluid level.
Controls and Cables: Test the throttle, clutch, and brake controls to ensure they operate smoothly and without any binding or sticking. Lubricate the cables if necessary.
Air Filter: Inspect the air filter for dirt or debris accumulation. Clean or replace it if needed to ensure proper airflow.
Spark Plugs: Remove the spark plugs and check their condition. If they are worn out, corroded, or damaged, replace them with new ones.
Lubrication: Lubricate any moving parts that may require it, such as the chain, cables, and pivot points.
Test Run: Once you've completed the above checks, start the motorcycle and let it idle for a few minutes. Observe for any abnormal noises, vibrations, or smoke. Take a short test ride to ensure the engine, brakes, and other components are functioning properly.
It's worth noting that these recommendations may vary depending on the specific motorcycle model and the duration and conditions of storage. Referring to the manufacturer's guidelines in the owner's manual can provide additional guidance for your particular bike.
