How to Change the CVT Gear oil on a GY6 150cc & 169cc Engine

This video will help you to change a gear oil on a 150cc & 169cc gy6 engine . Most GY6 Engines recommend changing the gear oil at least every 1500 miles. At the rear of the CVT on the left side of the Engine there are drain and fill plugs for the transmission. Place the oil drain container under the drain plug. Now remove the filler plug first, then the drain plug will drain out then screw the drain plug back into the transmission case. To refill the transmission, you squirt oil into the fill hole until it runs back out. That's your level check! Use the recommended oil, which in most cases is 80W-90 syntheyic gear oil . To get it into the small hole you need to buy the oil in a plastic bottle with a long plastic tip, which you can use to directly squirt oil to the transmission fill hole. When it starts to run back out, it's full and you can replace the fill plug . You will need a 12mm socket wrench and about 10 minutes of your time. thank you for watching
