how to change oil in a 1986 honda gold wing motorcycle
honda does
Since you didn't mention the exact model, I've researched all four Honda Motorcycle models in 1983, with 1100cc engines. These include the 1983 Honda CB1100F Super Sport 1100 (valued at $3,515 retail), the 1983 Honda GL1100A Gold Wing Aspencade(valued at $3,030 retail), the 1983 Honda GL1100I Gold Wing Interstate (valued at $2,550 retail), and the 1983 Honda GL1100 Gold Wing (valued at $2,420 retail).

Most motorcycles (with the notable exception of Honda Gold Wings) don't have reverse gear.
The Goldwing is a motorcycle built by Honda. One of the best places to get information on any Honda motorcycle is through a Honda dealership. Another is directly from the Honda USA website. The Gold Wing Road Riders Association or GWRRA may be able to assist with valuable information from experienced users as well.
Go to auto shop.
Should be 3.2 to 3.5 liters, that's with the oil filter changed.
pump it up to around 2.5- 3 Bar If it is a large bike like a gold wing, then 32 front and 40 lbs rear.
I would guess the motorcycle itself is worth about 3000-4000 dollars. The side car about 1000. I sold a 88 1500 for 6500 in 2003
Opinions differ but many owners prefer 15-40 W oil. The standard engine oil sold by Honda is recommended by them but there are also more expensive motorcycle oils available. Which one is best is an individual opinion.
