Ok so now that we got the fuel to oil ratio figured out. where do you mix it? Do I take my 6 gallon gas can and mix in 15.36 ounces of oil right in the can and shake well before filling bike? or do I keep the gas in the can clean and mix the oil in my 2 plus gallon tank on the bike.
I just take a sip of oil and a whole mouthful of gas, then swish and spit in the tank. I do this about 50 times and I'm good to go. It's probably bad for you though.
I've been doing 1 gal at a time like CSS, but that takes too long. I'm switching to a 2.5 gallon container. Supposedly you shouldn't mix more than you'll use in the short term. "Ratio Rite" cup is a must. I also got tired of all the spillage and bought one of these pump gizmos:
Oil in first, fill with gasoline will mix it good enough. Premix does separate over time...but it's nothing to get paranoid about. You don't have to give it a shake, fill 1/2 your tank, give it another shake, top the tank off.
The 'sip-n-spit' method I'm sure mixes things up pretty good. You would want a good flossing and brushing prior, though. Don't want any bits of left over meal getting into your carbonator.
