Special Call-Outs for 2016 Cobra CX50SR Owners

  • Always use Cobra Venom 3 Shoe Clutch Milk for this model; improper oils reduce clutch and transmission life.
  • Do not exceed 350 ml (12 oz)–more oil will degrade engine performance.
  • Leaning the bike left on the side stand helps fill oil more neatly.
  • Change the transmission/clutch oil every two hours of riding or after riding in muddy/wet conditions for best clutch performance.

Step-by-Step Oil Change Procedure

  1. Warm up the engine:
    • Start and run the bike for 5-10 minutes to warm the oil–the oil becomes thinner and drains out more completely.
    • Make sure the engine is not excessively hot to avoid burns.
  2. Prepare your work area and tools:
    • Set the bike upright and stable (use a bike stand if available).
    • Gather tools, oil, funnel, and measuring cup. Lay out shop towels to catch any spills.
  3. Drain the old oil:
    • Locate the oil drain plug on the clutch cover, near the brake lever (right side of the bike).
    • Place the oil catch pan under the drain plug.
    • Carefully remove the drain plug using the 5mm Allen wrench.
    • Allow oil to fully drain–tilting the bike gently can improve flow.
  4. Reinstall the drain plug:
    • Inspect the plug and its gasket; replace if worn.
    • Wipe any old oil from the area and plug.
    • Reinstall the drain plug hand-tight and then snug with the Allen wrench–do not overtighten.
  5. Measure new oil:
    • Using the measuring cup, pour 300 ml (10 oz) of Cobra Venom 3 Shoe Clutch Milk.
    • You may use as little as 8 oz (235 ml) for standard use, or up to 12 oz (350 ml) to maximize clutch life–never use more than 350 ml.
  6. Add new oil:
    • Remove the oil fill plug from the top of the clutch cover using the 5mm Allen wrench.
    • Insert the long-neck funnel into the fill hole.
    • Slowly pour in the measured Cobra clutch milk—take care to avoid spills.
    • Leaning the bike gently to the left makes filling neater and easier.
  7. Reinstall the fill plug:
    • Ensure the gasket is in place.
    • Thread the plug by hand, then snug using the Allen wrench–again, do not overtighten.
  8. Dispose of old oil:
    • Pour the drained oil into a sealed container and take to a moto-friendly recycling center.
    • Wipe down any residual oil from the bike.
