Tools and Supplies Needed

  • Sockets & Ratchet: 8mm, 10mm, 12mm sockets for drain plug, magneto cover, oil filter bolts

  • New Oil Filter
  • Replacement Gasket Washer (for drain bolt and magneto cover bolt)
  • Engine Oil: Suzuki recommends SAE 10W-40, API SF/SG or SH/SJ with JASO MA. MOTUL 300V 10W-40 is a popular choice
  • Gloves (optional, for cleanliness)

Before You Begin

  • Always change the oil with the bike upright on a level surface.
  • Warm up the engine for several minutes—this helps the oil drain more easily and carries contaminates out with it.
  • Allow the bike to cool slightly until it’s comfortable to touch—hot oil can burn.

Steps to Change the Oil

  1. Remove the Filler Cap:
    • Using a crescent wrench (never pliers, which can damage the cap), unscrew the oil filler cap to allow air in for smoother draining.
  2. Remove the Magneto Cover Guard:
    • Unbolt the guard using the appropriate socket (usually 8mm or 10mm).
  3. Remove the Drain Plug & Magneto Cover Bolt:
