How do you change the oil on a Yamaha QT50?
It is a 2 stroke engine so there is no oil to change. Note: It is true that many (but not all) two stroke engines (think weed-eater) just used mixed oil and gas. The Yamaha qt50 and many dirt bikes actually have an oil feed system that delivers oil to the carburetor. This helps because at low RPMs, there is too much oil in the mixture normally. This system allows the oil to go in less at low speeds, and more at high speeds. Many people still use mixed fuel either because they don't realize it, or have a broken oil pump.
