To change the gear oil on a 1994 Kawasaki Ninja EX500, start by warming up the engine slightly to thin the oil, then turn it off. Locate the gear oil drain bolt at the bottom of the transmission and remove it to drain the old oil into a pan. Once drained, replace the drain bolt and remove the fill plug on the side of the transmission, then use a funnel to add the recommended gear oil until it reaches the fill level. Finally, replace the fill plug securely, and check for any leaks.
