That seems a little rough to me. It's fine for the two strokes, but 206's...wow! Even for the greater majority for 2 cycles (Eg: Yamaha's, Tags, etc), 110 is NOT needed. Only the shifters and Superkarts realistically need that level of octane.
We road race, so our fuel supply is generally available on site in the paddock area. For all 2 cycle classes, we spec Sunoco 110 Leaded Race Fuel. For the 206's we spec. Sunoco Ultra 93 unleaded, the same stuff you can get at your local gas station. But again these fuels are available at the track in regular credit card gas pumps. For events where the fuel supply must be brought in, a local gas station is usually pick from the surrounding area, and a specific pump and octane level is picked, and that's where all the 206 folks MUST get their fuel. The Charlotte event is a good example.
I suspect you also pay a premium for VP 110. Like maybe $9-10 per gallon? Not really a big deal since you likely burn less then a gallon per event, but still!
Brian, you guys would know better the I, but in a 206, would the slower burning 110 end up spending most of it's energy in the pipe and not in the engine. I'd be curious to see the drop in HP using 110 octane vs. 93 (or 87). And also the increase in pipe temp vs. HP loss. Interesting, but pretty useless information :> Maybe sometime when you don't have anything better to do!!!!
And really, per the Briggs 206 rules, they "recommend" 94 octane max, available at standard service stations. VP110 doesn't really fit that.
SIRA should really consider changing their 206 fuel requirements to a local gas station and get away from the 110 leaded race fuel stuff.
Just my $0.02. Have a good day, stay safe.
