Well,that's hard to say,Josh. Drops= teaspoons which =Tablespoons which 2 of those equal one OZ.,correct? Drops are all different sizes also,so you can't say so many drops.
Here's what I did.................(1)Fill your gas tank and your OIL INJECTION tank to the brim.
(2) Run the bike for a coupla gallons of gas and see EXACTLY how many ounces of oil it takes to fill the oil injection tank back up to the brim.If it takes,say 7 oz.,that means it's injecting 3.5 oz. of oil per gallon,roughly a ratio of 35:1,which is great!
But when I checked my Streetmate's it was only injecting at 62:1.I keep mine hooked up,but premix 1.5 to 2 oz. of oil per gallon also. don-ohio (:^)
