I would be using a 25:1 fuel/oil ratio for breakin with a duration of two gallons worth of fuel for breakin using CONVENTIONAL 2 cycle oil during that time with the Zeda 80 which is a much better motor than those bargain specials you were used to...lol.
That would be 5.12 ounces of oil, I used Valvoline multi-purpose 2 cycle oil for this purpose that you can get at Autozone quite easily, and I then added that measured amount of oil using any ordinary kitchen use measuring cup to one gallon of gas in a gasoline jug, (Try and find Ethanol-Free gasoline as this gas will minimise future motor and carbuertor problems that ethanol causes in 2 cycle motors on these bikes), NEVER mix in the gas tank because you cannot shake the gas tank like you can the gas jug to have it mixed properly...Always shake the gas jug vigorously before pouring the mix into the gas tank.
After those 2 gallons are finished with, I then change to full synthetic oil like Amsoil Dominator 2 cycle racing oil which is what I use but any decent synthetic oil should do you OK, I'm just very picky...lol.
The mix you want to use after breakin will be 32:1 which is 4 ounces of full synthetic 2 cycle oil to 1 gallon of Ethanol-Free gasoline.
