As I mentioned in my introduction post I have some questions about the 1985 Honda Big Red three wheeler I just purchased. I honestly dont know too much about this machine and it has no owners manual so I could really use some help. What I do know about the machine is it is a 250cc engine with electric start, reverse and shaft drive.

1, How much oil does the crank case hold when I change the oil?

2, What viscosity should the oil be (example 10w-30) and do I seasonally adjust the viscosity for winter and summer?

3, What is the NGK spark plug number and what is the spark plug gap?

4, Is regular leaded gasoline ok to use or should I run premium gasoline?

5, What kind of oil is recommended for use in the shaft drive differential?

That seems to be all the questions I can think of right now, I am sure there will be more coming though. Thank you to any and all who help me out. Northshore.
