For me, with fuel pumps dispensing litres and oil coming in litres, I'd have to be a disfunctional derelict of some kind not to figure out how to come to ANY ratio.
BTW - 32:1 is the "it's not my fault" ratio and you can't go wrong. Whatever that 100:1 thing was earlier tells you that the poster needs a Ratio-Rite. S-T-U-P-I-D.

My bike was running like crap on my way home from work so I stopped at a gas station to get some NOS. I poured in 2 bottles and rode it home. Well I don't think it helped because it ran even worse on the way home and now it won't start. Any ideas?"
CLASSIC!!!!
HOWEVER, if you increase the amount of oil in the mix the fuel/air mixture actually becomes leaner. Let's say you run 40:1. Your premix is 97.5% gas and 2.5% fuel
(roughly). If you were to 'richen' to 20:1 then you would have 5% oil and 95% gas - ie less gas (per gallon of pre-mix). So, as the air is the same you effectively lean out the fuel/air mixture, meaning that you would have to go richer on the jetting to compensate.
So, putting more oil in the gas actually makes the bike run leaner.

Pit Row
128 * 5 / 32
Google will calculate that for you:
Google can easily calculate that for you: 128 * 5 / 32 = 20
That's 20 ounces of oil. For 40:1 (which is what I run) you need 16 ounces (1 pint, or 1/2 quart):
128 * 5 / 40 = 16
Google is good at converting units as well. For example, type "1 gallon in ounces" in the search box and it will come up with 128. Type in "16 ounces in quarts" and it tells you "0.5".
