i had my 2008 roughhouse r50 all apart the other day and i figured out the person before took out the flasher ass. i don't know why.. but i saw this tube that came off the plastic that surrounds the head of the motor and it was crushed so no air is able to go through. im not sure how that tube is supposed to go. does the other end go to the air box?
It does not go into the airbox. It sits near the airbox intake hole so it can get warm air from the head of the engine when it is cold outside. Helps keep gasoline in a mist or gas suspension instead of pooling in the intake tract.
