* Owner's Manual is Key: The most accurate information will be found in the owner's manual for your specific 1985 Yamaha TY250.

General Tips for Oil Changes:
* Use the Right Oil: Make sure you use the correct type of oil (typically a 10W-40 or 10W-30 for most motorcycles) and the correct amount.
* Follow the Manual: The owner's manual will have instructions on how to drain and refill the transmission oil.
* Don't Overfill: Overfilling the transmission can cause damage, so it's essential to stick to the recommended capacity.
