Motorcycle Safety & Driveability: Fuel requirements, honda trail 90, gasoline and water

Question
What type of fuel should I use for a 76 Honda Trail 90 bike?  85%, 87% or higher octane?

Answer
Loretta,

Back in 1976, gasoline and water were almost interchangeable, so anything that comes out of a gas station today will run your Honda 90. I'd use plain regular unleaded (the cheap stuff), 87 octane, since anything with a higher octane is going to generate more heat and not any more power.

Enjoy that old Honda!
