I came up through that same period. We were told wrong. I attended a training session about fuel for Harleys a while back. Was taught that if the motorcycle was stock and did not ping it was ok, even better for fuel economy and power, to run lower octane fuel. Octane simply raised the ignition point of fuel, preventing preignition . The lower the octane the easier the gas releases energy providing more power and fuel mileage . In my case my mileage with reg gas is about 40mpg and with premium about 38. In the heat of the summer I do run mid or premium more if it is available.

I think heat has a lot to do with it. My EVO will run on regular all the time. The 88 likes mid or premium when it gets hot. Both of them are carberated. The 96, injected with PC, pretty much likes premium all the time, and gets the worst mileage of all.
GNee's 88, carbed and built to 95, uses nothing but premium, gets the best mileage of any.

High test dosen't have ethanol. Ethanol boosts the octane level and can't be in high test. Be sure to frequent stations that sell a lot of premium as the octane degrades over time.

As for playing with curves, based on his first post, I doubt he's ready for that or for setting the timing off of the flywheel.
Depending on the vacuum the voes is set to open it may not retard in time. Baggers use higher vacuum level to retard than lighter bikes like fxr and sporty.

Wither the Dyna 2k you have 4 curves without touching mechanical position. Just change dip switches.

I don't understand your comment. I can get corn free 93 octane locally but most 93 I see around has up to 10% ethanol.

I live in NC but not all states are the same regarding gas laws.

It is not so much selling a lot of premium as it is how much business they have. The percentage of the public buying premium vs the 87 people will naturally rise in a prosperous station. More premium sold means faster tanker refills keeping the octane high.

Back when the feds made all the stations pump unleaded it was never shown that Phillips 66 always had unleaded fuel. My father called it white gas and used it to fuel his Coleman lanterns and stove.

Bullshit.

You roll the throttle on a vtwin and the vacuum drops under 5 before the accelerator pump spray hits the intake

This.

And Harley owners seem especially susceptible.
