Kawasaki Concours 14 Engine Oil, Final Gear Case Oil Specs

The recommended engine oil types for the Concours 14 include API SG, SH, SJ, SL, or SM with JASO MA, MA1, or MA2 ratings.

Additionally, the recommended viscosity is SAE 10W-40.

The engine oil capacity of Kawasaki Concours 14 is 4.7 liters (5.0 US quarts).

Oil Capacity and Type

The engine oil capacity varies depending on the maintenance scenario:

  • 4.0 L (4.2 US qt) without removing the filter.
  • 4.4 L (4.7 US qt) when the filter is removed.
  • 4.7 L (5.0 US qt) when the engine is completely dry.

It’s crucial to note that chemical additives should not be added to the oil, as the recommended oils are fully formulated to provide adequate lubrication for both the engine and the clutch.

Recommended Engine Oils

To meet Kawasaki’s specifications and ensure the best performance for your Concours 14, it’s recommended to use:

  • Kawasaki Performance 4-Stroke Motorcycle Oil
  • Kawasaki Performance 4-Stroke Semi-Synthetic Oil
  • Kawasaki Performance 4-Stroke Full Synthetic Oil

These oils and other 4-stroke oils with API SG, SH, SJ, SL, SM, and JASO MA, MA1, and MA2 ratings are suitable for the Concours 14. The recommended viscosity is SAE 10W-40.

Engine Oil Maintenance

After an oil change, allowing the engine to run at idle speed for two or three minutes is essential.

This ensures that the oil has a chance to circulate and reach all the vital engine components, providing optimal lubrication.

Regular Oil Level Inspections

Checking the engine oil level is a simple yet critical maintenance task.

The oil level should be between the upper and lower level lines indicated on the oil level inspection window.

To avoid engine seizure, it’s emphasized that the oil level should always be at the upper-level line.

Steps for Oil-Level Inspection

  1. If the oil has just been changed, start the engine and run it for several minutes at idle speed to fill the oil filter.
  2. Wait for the oil to settle, ensuring accurate readings.
  3. Check the oil level through the inspection window with the motorcycle level.
  4. Adjust the oil level if necessary, adding or removing oil as required.

Importance of Regular Oil Changes

Regular oil changes are paramount for maintaining the optimal performance and longevity of the Concours 14.

Over time, dirt and metal particles accumulate in the oil, diminishing its lubricative properties.

Ignoring timely oil changes can lead to accelerated wear, potential engine or transmission seizures, and an increased risk of accidents and injuries.

Final Gear Case Oil

The final gear case in the Concours 14 also requires specific attention to ensure proper function and longevity.

Final Gear Case Oil Specifications

  • Oil Capacity: Approximately 160 mL (5.41 US oz.)
  • Oil Type: API “GL-5” Hypoid gear oil
  • SAE 90 above 5°C (41°F), SAE 80 below 5°C (41°F)

Oil Level Inspection

  1. Use the center stand to keep the motorcycle vertical on level ground.
  2. Remove the filler cap and check the oil level, adding oil if necessary.
  3. The oil level should reach the bottom of the filler opening with the motorcycle held vertically.

Oil Change

When changing the final gear case oil, follow these steps:

  1. Place the motorcycle on its side stand.
  2. Use an oil pan beneath the gear case.
  3. Remove the filler cap and drain bolt, allowing the oil to drain completely.
  4. After draining, install the drain bolt with a new gasket.
  5. Fill the gear case with the specified oil without turning the rear tire.

It’s essential to use the same type and brand of oil already in the final gear case to ensure compatibility and optimal performance.

Fork Oil

Approximately 445 mL (15.0 US Oz) per side when changing the oil.

Recommended fork oil for the Kawasaki Concours 14 is Kayaba 01 (KHL15-10) or an equivalent SAE 5W oil.

Oil Leak Solutions

Oil leaks in Kawasaki Concours 14 are mainly due to the Cam Position Sensor O-ring.

Cam Position Sensor O-Ring

The Cam Position Sensor O-Ring in the Kawasaki Concours 14 may develop leaks over time.

Source slightly oversized O-rings to fix this issue.

Valve Cover Gasket

Another potential source of oil leaks is the valve cover gasket, especially if a valve adjustment has been performed without replacing the gasket.

This repair might be a bit more involved but is manageable with the right guidance.

Let the bike sit for a while and observe any leaks before removing the fairings for a closer inspection.

Check for worn or damaged gaskets, faulty plugs, or worn-out countershaft seal if the motorcycle is still leaking oil.
