Probably not.

http://en.wikipedia.org/wiki/Octane_rating

In the US we use: (R+M)/2

 

Laughing. The thousands folk blow on these bikes, and your going to knot your knickers over a little bit of gas?

 

Yep, I remember them.
When I was a kid, the next door neighbor had one like that.
Was in the mid 60's then, so the bike was probably early 60's model perhaps?

Nothing in recent memory, but they did work that way.

 

There are several methods to come up with an octane number:

Research Octane Number (RON)
The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.

Motor Octane Number (MON)
Another type of octane rating, called Motor Octane Number (MON), is determined at 900 rpm engine speed instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern pump gasoline will be about 8 to 12 octane lower than the RON, but there is no direct link between RON and MON. Pump gasoline specifications typically require both a minimum RON and a minimum MON

Anti-Knock Index (AKI) or (R+M)/2
In most countries, including Australia, New Zealand and all of those in Europe,[citation needed] the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI), and often written on pumps as (R+M)/2). It may also sometimes be called the Posted Octane Number (PON).

Difference between RON, MON, and AKIEdit
Because of the 8 to 12 octane number difference between RON and MON noted above, the AKI shown in Canada and the United States is 4 to 6 octane numbers lower than elsewhere in the world for the same fuel. This difference between RON and MON is known as the fuel's Sensitivity,[4] and is not typically published for those countries that use the Anti-Knock Index labelling system.

 

well you should have been at the motorcycle shop, not the corral.

early Vtwins...

here's a pic of my '53 FLF.
This is an electronic ignition sensor conversion- normally points and condensor would be used- but it works the same.

the cable with solid wire core is connected to the left grip, and will rotate the housing around the rotor- this allows the spark timing to be adjusted

the position shown is fully retarded- so that when you start the bike it won;t shoot your knee into the bar end and give you a scar that looks like a little smile...and a limp

100% CORRECT & RIGHT ON TARGET!

53 was my birth year. Do you have just one little smile scar?

 

Not exactly - 95 octane in Europe is only 90-91 here - their 101 octane is like our 93-94 octane.


BOSUXFan, do you have an export bike or did you bring yours with you? they may have tuned the HDI bikes differently. I hate to say it, but what does your owners manual say?
