I'm assuming you mean the clutch hydraulic fluid line.
There's nothing that complicated except to note where it is routed before removing the old line. This is the procedure (more or less) as shown on page 2-33 of Service Manual (99501-05):
- Remove secondary clutch actuator cover and place a catch container below to catch the fluid.
- Remove clutch line flare nut fitting from secondary clutch actuator and allow fluid to drain.
- Remove banjo bolt from clutch fluid reservoir.
- There are three clips on the right side lower frame rail that hold the line in place that need to be removed
- Pull the banjo fitting end out through upper triple clamp and pull down along right front down tube below radiator.
- Pull the flare nut end out along the lower frame rail and out through the front down tubes.
- Reverse this procedure for clutch fluid line installation.
- Bleed clutch.
