i have a 2004 suzuki eigar that will start but it soon starts smoking real bad then chokes its self out then the air box is full of oil an when you check the oil it runs out of the dipstick hole i know its a mad promblem but where do i need to start

 

how much oil do you have in it?

 

As said by nate85, overfilling is 1 case, however it would need tobe VERY much over. Probably rings allowing crankcase to pressurise and blowing oil out.
But check lever first. They hold about 3.5litres.
