How do you check the oil on my 1978 suzuki rm80?

To check the oil on your 1978 Suzuki RM80, start by placing the bike on a level surface and ensuring it is upright. Locate the oil fill cap, which is typically found on the right side of the engine. Remove the cap and use a dipstick, if available, to check the oil level, or visually inspect the oil inside. If the oil is low, add the appropriate type of oil until it reaches the desired level, then securely replace the cap.
