My Yamaha won't turn over and it won't start; the airbox keeps filling up with liquid too...

will someone please help me?!?

 

what kind of yamaha is it?

 

Moto 4 350 can you help me?

 

what year is it and what kind of fluid?

when was the last time you checked the oil? did you over fill it?
do you shut the fuel off when you park it ?
I would think either the floats are sticking and it flooding fuel into the engine and air intake or you have too much oil in it and it my be blowing into the air box threw the crank vent!
