Step-by-Step Guide to Adjusting Your Harley Davidson Shocks
Follow these steps to safely and effectively adjust the air pressure in your Harley Davidson shocks.
Step 1: Prepare Your Motorcycle
Park your motorcycle on a level surface. This ensures accurate pressure readings. Let the shocks cool down if you’ve recently been riding, as heat can affect the air pressure.
Step 2: Locate the Schrader Valve
The Schrader valve is usually located on the top of the shock absorber. It may be covered by a protective cap. Remove the cap and set it aside.
Step 3: Clean the Valve
Use a clean rag or shop towel to wipe off any dirt or debris from around the Schrader valve. This prevents dirt from entering the shock when you connect the pump.
Step 4: Connect the Air Pump
Attach the air pump’s connector to the Schrader valve. Make sure it’s securely connected to prevent air leaks. If your pump has a locking lever, engage it.
Step 5: Check the Initial Pressure
Read the pressure on the pump’s gauge. This gives you a baseline to work from. Note the initial pressure.
Step 6: Add Air (If Needed)
If the pressure is below the recommended range in your owner’s manual, begin pumping. Use short, even strokes. Watch the gauge carefully and stop when you reach the desired pressure.
Step 7: Release Air (If Needed)
If the pressure is too high, use the pump’s bleed valve (if equipped) to release small amounts of air. If your pump doesn’t have a bleed valve, carefully depress the Schrader valve core with a small tool (like the end of a pen cap) to release air in short bursts. Check the pressure after each burst.
Step 8: Disconnect the Pump
Once you’ve reached the desired pressure, disconnect the pump. The no-loss connector should prevent any air from escaping. If your pump has a locking lever, disengage it first.
Step 9: Replace the Valve Cap
Replace the protective cap on the Schrader valve. This keeps dirt and moisture out.
Step 10: Test Ride
Take your motorcycle for a short test ride to see how the adjusted air pressure feels. Make further adjustments as needed to achieve the desired ride quality.
Air Pressure Guidelines
The correct air pressure for your Harley Davidson shocks depends on several factors, including:
- Motorcycle Model: Different models have different recommended pressures.
- Rider Weight: Heavier riders need more air pressure.
- Passenger Weight: If you frequently ride with a passenger, you’ll need to increase the pressure.
- Cargo Weight: Carrying luggage or other cargo also requires higher pressure.
- Riding Style: More aggressive riding may benefit from slightly higher pressure.
Always refer to your owner’s manual for the specific recommended air pressure range for your motorcycle. Here’s a general guideline, but remember to check your manual:
| Motorcycle Type | Typical Air Pressure Range (PSI) |
