C13 - Removing Primary Chaincase

1) Remove the 3 nuts attaching the left hand foot rest. You don't have to disconnect the stop lamp wires or brake cable - you can let them hang. In fact you'll want to leave the brake connected as it can come in handy for removing/tightening the sprocket or clutch nuts.

2) Since there's no drain plug, when you crack the cases open the oil spills out quickly. Catch it in a pan of some sort.

3) Remove the center sleeve nut and rock the cases apart. There are two alignment dowels you have to clear. Never pry the cases apart by placing anything between them.
