I did the math, thats 25:1 , gas: oil, right?
Correct.
A 25l fuel can with a litre of oil in it first is 4.16%, that’s what I run. Easy!
In 2 stroke does it matter if the fuel is ethanol based or non-ethanol?
Yes. High-ethanol fuel is superior. It gives a power increase by being an oxygen carrier, and it increases RON quickly. E15 93 octane pump gas from at least one major brand is 101 RON now, so you can be aggressive with jetting and timing.
You are only allowed 4% in Sweden, and only Aspen + fuel is allowed for practice and race.
Motul 2t Grand Prix is a good oil and cheap from mondo
You may not pass tech with ethanol content in your fuel, if that’s a factor.

i usually cheat and just use normal fuel 98ocktan with wladoil, Only in race i use aspen so the greta tunberg can be happy

I’d prefer to still use aspen on practice days since you have to run it slightly different. Builds way less carbon than regular fuel does.
I am so naive to anything 2 stroke. Thanks ya’ll.
What is your opinion on using 100LL for a ka100?
It’ll be safe, but slower than racing or pump gasoline with an adequate octane rating as it isn’t oxygenated.
