DO NOT mix oil in the gas on your four stroke engine. You will foul the spark plug(s), build up deposits on the valves and head, and make a smokey, smelly mess. A two stroke engine uses the fuel/oil mix to lubricate the engine before being used as fuel. A four stroke engine has a separate lubrication system and does not normally burn any oil. As the name implies, a two stroke engine works in two strokes. The first stroke is downward, where the fuel/oil mix and air are drawn into the cylinder. The momentum from the crankshaft counterbalance or force from the other cylinder(s) drive the piston back up compressing the mix, and the spark plug sparks at or slightly before the top of the stroke. The rapid combustion of the fuel/oil/air mix drives the piston down, which is the power stroke, and then the cycle starts all over again. A four stroke engine has an intake stroke down taking in the fuel/air mix, a compression stroke up, a power stroke down as the fuel/air mix is ignited at or before the top of the stroke, and a exhaust stroke up before starting all over again. A four stroke is much cleaner and more reliable than a two stroke, but it is heavier and has less torque. A two stroke engine is much lighter and has more torque, but takes more maintenance.

the correct ratio is 32:1. thats 4 ounces of oil for every gallon of gasoline. if your riding it hard or in very hot wweather, you can even go 28:1, or 5 ounces to a gallon. dont go any less, or you risk damaging your engine. and dont use more then 5 ounces per gallon, or you willl have poor performance. the manufacturers back then reccomended using very high amounts of oil, like a 20:1 ratio, but with our better technology and more advanced oils, that is not neccessary. just remember, either 4 or 5 ounces to a gallon, and both you and your bike will be happy.
