Answer:Given the make and year, I would go with a 10W40 viscosity. I own a Chilton's Motorcycle Repair Manual (1959-1981) and in the Yamaha XS360-400 section is states "When the average air temperature is above 5 degrees Celsius (41 degrees Fahrenheit), use Yamalube 4-stroke oil, or SAE 20W-40, service rating SE or SF. When air temperature is consistently below 15 degrees Celsius (59 degrees Fahrenheit), use SAE 10W-30, service rating SE or SF."
Which one?
81hp
600cc
6 volts
The oil capacity for a 1981 Yamaha Maxim 650 is approximately 3.5 quarts (or about 3.3 liters) when including the oil filter. It is important to check the owner's manual for specific guidelines and recommendations regarding oil type and maintenance procedures. Always ensure the bike is on level ground and check the oil level after filling to avoid overfilling.

The seat height of a 1981 Yamaha Maxim 550 is 29.3 inches. That height not really adjustable, but frame modifications would probably lower it.
