How to Add Shock Absorber Oil for Motorcycles?
2 Answers
Adding oil depends on the type of the shock absorber. Generally, you can add oil by unscrewing the top cover screw, but do not overfill it, as this can make the shock absorber too stiff. For motorcycle hydraulic shock absorbers, regularly check for any oil leakage and ensure the shock absorber oil is sufficient. Additionally, it's important to replace the shock absorber oil periodically. Under normal circumstances, replacing it once a year is sufficient.
Take it step by step and don't rush. First, prepare the tools: shock oil of the appropriate specification, a syringe, a measuring cup, and a wrench set. Use a paddock stand to stabilize the motorcycle, then remove the screw cap at the top of the shock absorber—remember to place a cloth underneath to catch the old oil. Slowly drain the old oil completely, and take the opportunity to check if the spring is deformed. Next, thoroughly clean the inner tube with a cleaner, as grease can affect the performance of the new oil. Then, measure the specified amount of new oil with the measuring cup and slowly inject it using the syringe. After each refill, I gently press the shock rod a few times to release any air bubbles. Finally, tighten the screws and test the rebound. Different models require different oil quantities, so it's best to consult the manual or check with the manufacturer.
