|
| If the oil separates on the vertical run BEFORE the hose loops down, it will fall back into the tranny/primary compartment. \\ |
| If the oil separates (or not) AFTER the hose loops back down, you'll end up with an apparent leak or drip from the hose. \\ |
|
| ==== 1986-1990 Vent ==== |
| **Hose and fitting**: \\ |
|
| The vent line is run out “open ended” and not attached to anything on the other side. \\ |
| There is no mention of the transmission vent in the 1991-1999 FSMs. Furthermore, there is no illustration showing routing of the vent hose. \\ |
However, there is an accepted method on the XLForum of running the hose from the XLForum that serves the purpose well. \\ |
| With the object being a fully open path without kinking the hose; \\ |
| * The vent hose is raised up high under the seat, behind the battery box with a wide loop down toward the center of the seat downtubes. \\ Make sure that you manage a wide loop that will not eventually close the ID of the hose. \\ The hose is then left hanging low (tied off). Some run the hose end down behind the swingarm. \\ Some run the hose out past the center of the seat tubes, wedging it between the center rear tube and an adjacent L or R outside tube as in the pic below. |
|
|
| **Vent hose routing**: \\ |
The vent line is run out “open ended” and not attached to anything on the other sideend. \\ |
| Again, there is no mention of the transmission vent in the 2000-2003 FSMs and no illustration showing routing of the vent hose. \\ |
| Therefore there is no understanding of the original hose routing in early 2000 other than the service bulletin below. \\ |

| 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. |
