The Kayo T6 dirt bike employs the same engine as the new, Zongshen RX3 (ZS250GY-3). Although the engine and transmission share the same oil, the NC250/ZS177MM engine has two oil drain plugs. The engine also has two coarse oil filters, and a fine oil filter. The following video shows how to change the oil, and service the oil filters for the NC250 engine.
