Suzuki RM85 2019 Owner's Manual

To break in a new engine, start by riding at low speeds and avoid full throttle for the first hour. Gradually increase speed and load, allowing the engine to cool between sessions. After approximately 10 hours, change the engine oil and check for any loose bolts or parts.
Regular maintenance includes checking and cleaning the air filter every ride, changing the oil every 6-10 hours of use, inspecting the chain and sprockets, and checking tire pressures. A thorough inspection and servicing should be done every 20 hours.
If the bike won't start, check the fuel supply, ensure the spark plug is clean and functional, and verify that the kill switch is in the correct position. Additionally, inspect the carburetor for any blockages or issues.
Use a high-quality 2-stroke motorcycle oil with the recommended viscosity as per the owner's manual. It's important to mix the oil with gasoline at the correct ratio, usually around 32:1 or 40:1, depending on riding conditions and performance needs.
Adjust the suspension by tuning the preload, compression, and rebound settings. Refer to the owner's manual for default settings and adjust based on your weight and riding style. Test changes incrementally to find the best setup.
Common causes include a clogged radiator, low coolant levels, or a faulty water pump. Ensure the radiator is clean and free of debris, check coolant levels regularly, and inspect the water pump for proper function.
The air filter should be checked and cleaned after every ride, especially in dusty conditions. Replace the air filter if it shows signs of damage or cannot be cleaned effectively to maintain optimal engine performance.
The recommended tire pressure for the RM85 varies based on terrain. Generally, 12-14 psi for the front tire and 12-14 psi for the rear tire is suggested for standard off-road conditions. Adjust pressure according to specific track conditions and rider preference.
Regularly clean the chain with a suitable chain cleaner, and lubricate it with a high-quality chain lube. Check for proper tension, usually with 30-40mm of slack, and inspect for any signs of wear or damage. Replace if necessary.
The recommended spark plug for the RM85 is typically NGK BR10EG or equivalent. Ensure the spark plug gap is set correctly as per the manufacturer's specifications, usually around 0.6-0.7mm.
