its when you have either mixed your oil too rich or you need to ride more on the pipe.
it smokes out the exhaust...
the main difference is a two stroke has oil mixed into the gas weather it is oil injected or pre mixed(adding oil to gas yourself). a two stroke has no intake or exhaust valves,no pushrods,or rockerarms. intake and exhaust into the combustion chamber in done through the sides of the cyllinder walls.
4 stroke oil
Oil in the exhaust is part of the two stroke design but if you have too much, you should check the fuel/oil mixture or the oil injector settings.
4 stroke
Because of that ti have no valves the in let nad outlet are ports. S-13. (thanfu@gmail.com)
Your bike is a 2 stroke. since you are mixing gas and oil together oil naturally blows out your tail pipe. if this is happening, then there is nothing wrong with your bike, unless it is a 4 stroke.

That is the burnt two stroke oil. it is pretty normal
Two stroke Oil. Penzoil makes a good one
