How does the 2 cycle oil injection system hook up on a 1990 Yamaha RT180 motorcycle?

The line from the lube tank, under the right side of the seat, goes the the front right side of engine, under the front-most cover to the oil pump to the input connection. largest line. loosen up the bleeder screw until oil comes out, the smaller line runs to the right side of the carburetor on the right side at the throat of the carb. look to see if its been plugged. run the bike and open the throttle until oil comes out, on mine a 1990 model it took a minute or two to see the oil emerging from the feeder tube. that's it. mine was unhooked for who knows how long and started pumping pretty quickly. Good Luck...!
