Using low octane gas in Harley-Davidson motorcycle?
Harley-Davidson recommends using high octane (92+) gasoline in their motorcycles. Does anyone have experience using lower octane gasoline and does it make a difference on how the bike runs?
Alot of folks say it doesn't make a difference,..... the higher octane rating allows the cylinder to run a little cooler, and waits for the spark to light it off....... Detonation robs the air cooled motor of power. The higher octane doesn't necessarily make it run better, it just keeps it from running worse. I use about 25-40% avgas in the hottest part of summer to completely eliminate detonation problems.
