Ideally, check tire pressure before and after every journey. Commit to a weekly checking routine. Replace the tires if there is rapid pressure loss. Replace when there is about 1. 59mm (2/32” or 0. 063 inches) tread remaining all around the tire. Don’t wait till tires go bald. Always change tires in sets. Both tires go through the same stresses and rigors of road riding.
Check for any possible oil leakages. Carbon deposits thicken the oil, creating a drag in the movement of engine. Avoid running your bike on dirty oil. It will increase the consumption of fuel and drastically reduce the engine life.
Always change the air filter at recommended intervals; increase the cleaning frequency in particularly dusty conditions.
Don’t tighten your clutch too much – an over-tightened clutch may cause it to slip without your noticing. It also leads to increase in fuel consumption. Make sure you have the right clutch adjustments in place.
Clean the carburetor and maintain valve clearances. Clean out the carburetor, for every 1500 kilometers (900 miles) you travel. [5] X Research source Clean the spark plugs and check the gap every 750 kilometers (450 miles) for an old / antique two-stroke motorbike and every 1,500 kilometers (900 miles) for a four-stroke bike. Spark plugs should be changed as specified in the owner’s manual (or if a problem is suspected). It is critically important to use the correct spark plug grade and type. [6] X Research source Keep the choke clean and have it replaced immediately if it is damaged.
Provide regular lubrication, as well as cleaning and adjustment. Use paraffin to wash the chain. Use a piece of cloth and a soft brush to remove the dirt in the chain. Never use water to clean the chains, as that could rust the chain links. Wipe the chain with a clean dry cloth, once the dirt has been cleaned completely. Use your old engine oil to lubricate the chain links and the chain. Ensure that your bike’s chain has the proper tension and free play. Any variation will not power the rear wheel smoothly.
Cover the ignition switch unit, ignition coil and silencer using plastic sheets, before you start cleaning the motorcycle. Use a microfiber cloth to clean your bike. Avoid exposing your bike to direct sunlight; try to park your bike in the shade.
Top up the battery with distilled water, whenever required. Examine for any leakages from the battery. Keep the battery fully charged if the motorcycle is not used for long time.
Keep both the brakes holding the tire properly spaced. Brakes becoming too tight, or too loose, can be very dangerous. Tighten the brakes as per your personal style and requirement. Replace the bike’s brake pads in the front if screeching sound persists; this could also be because of a lack of oil. Replace all the front and rear brake oil with recommended (DOT 3 / 4 / 5) specification.
Change your bike’s fork oil, for once in every 12000 kilometers. Check forks and spring for rust or damage. Adjust your fork according to your preferences and comfort.
The usual wear-out limit for sprockets is 40,000 kilometers (25,000 miles). Change both the driving and driven sprockets, and the chain, at the same time. It’s not recommended to change only one part.
Check the fuel level every day to confirm you’re not leaking any fuel. Check all your fluid levels - oil, brake fluid and coolant, if applicable. Check the throttle cable play. Confirm smooth operation and that it returns properly to the closed position. Check steering lock and lever notches for any uneven feel or interference with the operation of any cables at full lock. Check brake pedal play, as specified in your motorcycle’s manual. Confirm the wear lining indicator is within usable range. Check drive chain slack, as specified in your manual. Check your lights and horn. Check the clutch lever play. Ensure smooth steering movement. Make sure there are no restrictions. Ensure both bike stands return to their fully upright position. Check the correct inflation pressure in both tires. Make sure you have adequate tire tread depth and no cracks or splits. Adjust the rear viewing span of mirror if needed. Ensure kill switch functionality. Check brake hoses for chafing or leakage.
Check oil level - does it require topping-up? Top up if so. Check your tire pressure with an accurate gauge. Check the battery. If it’s not maintenance-free, then check the electrolyte level and top up with distilled water if necessary. Check the control cables. Lubricate as necessary Check the brakes. Pads and disks should be checked for wear and replaced if necessary. Check and top-up your fluids. Adjust the drum brakes as necessary. Do a full visual inspection. Check for loose nuts and bolts and spokes. Check for fork seal leaks and any other oil leaks.
Check the spark plugs. Clean and adjust or replace;[12] X Research source anything other than a light/medium brown deposit may indicate problems. Check control cables. Adjust for free play. Check Idle speed. Adjust as necessary. Lubricate control lever pivots.
Change the oil and filter. Change the air filter. Check wheel and steering head bearings and grease them. Replace if necessary. Check the exhaust system for leakage.
Adjust carburetor synchronization - if applicable. Check overflow pipes. Replace any that are blocked or missing.
Do all the above half-yearly maintenance tasks. Replace spark plugs. [13] X Research source Check suspension linkages for play. Replace linkage, bearings, and bushes as necessary.
