| You add the air by removing the left saddle bag. Once the bag is removed you'll be able to see the valve for the air. Now keep in mind to ONLY use a bicycle pump, or Harley makes a small hand held pump,( item #HD-34633). Never exceed 35psi or you will blow out the components. Here is the amount of air pressure you should use for the amount of weight on the bike. Solo rider:0-150 LB'S=0psi. Solo rider: 150-200 LB'S=0-10psi. Solo rider: 200-250 LB'S=5-15psi. Rider with passenger: up to 150 LB'S=10-15psi. Rider with passenger: up to 200LB'S=20-35psi. Once you have put the right amount of pressure in the shock re-install the saddle bags. Ride Safe David. |
