The highest grade available. Up here, it's sometimes hit and miss, especially with 1.9 gal capacity. So I have had to borrow fuel sometimes from the friendly locals and who Knows? Bike hasen't missed a beat though.

sunuco 93. If you read your owners manual it says to run 91 or higher.

The manual states 87 or higher, they list the two different methods of octane rating and 87 is the number and method used on the pumps around here. I've noticed no difference between the 87 91 or 93, besides its mainly the anti knock index its not any more powerful or cleaner.

Thanks for the sanity Bryan. I thought the octane myth was going to run again. In actuality, on an engine that will run 87, the 87 will make more power. Octane is the measure of a fuel's resistance to ignition, do the math.
You will also get better mileage with the lower octane fuel.

The REAL rule : Use the lowest octane your engine will run on without detonation.

Correct. Super unleaded is NOT better fuel. It's less volatile. Plus if you let your bike sit during the cold months, the high octane will deteriorate quicker too. The bike runs fine on 87 & it's designed to run on 87. You will not get any increased performance from 91 and basically all you're doing is giving more money to a corporation who already has a license to print money.

Also most gas station have only one hose for all three grades. If the guy before you pumped 87, even if you pay for 91, you are getting about 1.5 gallon of 87 that's left in the system from the last time. So considering we only have 1.9 gallons, well you co the math.

That's a good point, FMT. I am having one of those "why did I not think of that" moments.

If the gas pump hose is 1 1/2" and is about 8 feet from the nozzle to where it switches different fuel types... there is 1.88 gallons in the line.... it is true...
