Fuel requirements for my SFC

Hi folks,
I've been looking through fuel specs for my bike and see it is listed as 101 octane, with 98 octane being acceptable for lower compression engines. šŸ˜Æ
We used to use 100 low lead in the Cessna at the airport many years ago, but the highest I can get at the pumps is 91 octane.
Wolfgang said he uses a lead additive with his fuel, but that won't boost octane and I believe that he can get a a higher octane fuel in BC.
Are there any decent octane boosters available in Canada that will make my engine happy (when I finally get to run it, that is!). Any other suggestions for available products to improve on fuel quality?

Thanks,
Frank
 
Update from Wiki via a friend:

In Europe, the octane rating on the pump is simply the RON figure. America, by contrast, uses the average of the RON and the MON figures, called the AKI (anti-knock index). Thus, 97 octane ā€œsuper unleadedā€ in Britain is roughly equivalent to 91 octane premium in the United States.Sep. 17, 2012

Yes, I was recommended to do the same by Gijs van Dijk for my 750SFC too. He specified 98RON. If you still have the original GRP (fibreglass) petrol tank stay away from ethanol fuels - or line your tank to prevent delamination first. I've had two tanks go that way.

I now use leaded race fuel with no ethanol which is available in a couple of grades here in the UK. Sunoco list one agent in Canada so not sure how viable this option is for you. Maybe VP Racing Fuels can help?

If you're referring to SFC1000, then ignore the above!

Thanks, Rob! I'm not even going to attempt to put fuel in the original tank. I'm just going to clean it up and put it on a shelf!

Wolfgang mentioned the same thing about using modern fuel in the original tank. He said it's not a good idea if I plan to use the bike at all. Hence the planned alloy replacement!

You can blend 100LL with 91 octane pump gas that has no ethanol and get very good results. That's what I use in my MGS-01.

If you want to find out where to get ethanol free gasoline just try this site .... Pure Gas

Thanks Jim!
I'm not sure if they would sell me the 100LL at the airport, but I'm planning to ask!
I run Shell premium in my Ducati (actually, in everything I own) and also have plenty of access to Irving gas here in New Brunswick!
Did you blend it as 50/50 or did you have a different ratio that you use?

I've also been looking into VP Racing fuels, but haven't found a source out here yet.
 
I have blended it 50/50 as the fellows at the racetrack suggested. Most airports here have no issues with selling fuel as long as they are not busy at the moment and you have an approved container. I have a 42 liter marine fuel tank that makes it worthwhile as I can buy 20 liters of AvGas and top up with either Shell 91 or Chevron 94 here in BC. The other nice part about AvGas is it never goes bad ......... as I like to say, think of the liability issues for the fuel manufacturers if one of those airplanes that sits for months and months at an airport then goes flying and crashes because the fuel went bad. They reckon the fuel is safe for 5 years but the official life is 2 years.

I have used VP fuels in my MGS-01 when I first bought it but I don't think it is worth the extra dollars unless you are above 11:1 compression and going hard on a racetrack.
