| + | **Vent hose and fitting**: \\ | ||
| + | Both the primary and tranny compartments vent through the one fitting on the top rear of engine behind the rear cylinder. \\ | ||
| + | The fitting (63533-41A) is a 1/ | ||
| + | (same fitting is used on the oil pump return outlet) \\ | ||
| + | The hose (63508-04) is short, preformed and is attached to the fitting with a hose clamp. \\ | ||
| + | |||
| + | **Vent hose routing**: \\ | ||
| + | Due to the shortness of the hose and it being preformed, there is no routing necessary. \\ | ||
| + | It is installed on the fitting with the open end facing the left side of the bike with the open end facing the rear of the bike. \\ | ||
| + | It is designed to run in front of the starter hidden between there and the rear cylinder. \\ | ||
| + | The hose end just peeks out the left side from behind the starter with a 90° bend on the end between the starter and back side of the primary case. \\ | ||
| + | Looking at the first pic below, you can see it is also formed to run at an up angle from the fitting before it turns down at the ending bend of the hose. | ||
