We have a Kasea 90 with a HC piston,(12:1) aluminum rod, CDI to 12,000 Bored 40 to become a true 90,then 10 over .Ported head,28mm flatside Carb, Carbone fiber reed cage full clutch mod, ok here is my question.....


The racing Co. that built it says we should run Opti fully synethic 80:1 with straight c-12 or min. 106 octane

I dont mean to second guess them, but holy cow.....80:1???!!!
Anyhow, were also looking for a differernt oil that would work well with the Kasea since this oil is hard to find around here ......Any suggestions????
