(00431b) WARNINGTo prevent accidental vehicle start-up, which could cause death or serious injury, remove main fuse before proceeding. (00251b) | ||||||||||||||||
| 2. | Remove main fuse. See owner's manual. | |||||||||||||||
| 3. | Raise the rear end of the motorcycle so that the rear wheel is just off the ground. Support the motorcycle with suitable blocking under the frame. NOTE Retain the original fasteners for installation of new shocks. | |||||||||||||||
| 4. | Remove the saddlebags from the motorcycle. See the Touring model's owner's manual for saddlebag removal. | |||||||||||||||
| 5. | Fasten the air pump, part number 54630-03A to the rear air suspension adjustment valve on the motorcycle. See the Touring model's owner's manual for valve location. Add 3-5 psi to clear the line but do NOT exceed 50 psi. | |||||||||||||||
| 6. | Using the pressure relief valve located below the gauge on the pump, release the air pressure from the rear suspension. | |||||||||||||||
| WARNING Use caution when bleeding air from the suspension. Moisture combined with lubricant may leak onto the rear wheel, tire and/or brake components and adversely affect traction, which could result in death or serious injury. (00084a) | ||||||||||||||||
