Investing in one of these manuals is arguably the best investment you can make for your FJ1200, providing invaluable peace of mind and saving you significant workshop costs in the long run.

The Critical Engine Oil & Filter Change

Changing your engine oil and filter is arguably the most important routine maintenance task you can perform. Engine oil lubricates moving parts, cools the engine, and cleans away contaminants. Over time, oil degrades and becomes contaminated, losing its effectiveness. A fresh supply of oil and a clean filter ensure your engine remains healthy, efficient, and performs optimally for years to come. For the Yamaha FJ1200, this process is straightforward once you know where everything is located.

Gathering Your Essential Gear

Before you begin, ensure you have all the necessary tools and supplies. Being prepared will make the job much smoother and quicker:

• New engine oil (approximately 3.35 litres for an oil and filter change)
• New oil filter
• New drain plug washer (crush washer)
• Oil filter housing O-ring/rubber sealant ring (optional, but good to have)
• Socket set (10mm socket for filter cover, appropriate size for drain plug)
• Torque wrench (absolutely essential for correct tightening)
• Oil drain pan
• Funnel
• Clean rags or shop towels
• Gloves (optional, but recommended)
• Centre stand (ideal for stability and correct oil level checking)

Locating Key Components on Your FJ1200

Familiarising yourself with the locations of the oil system components is the first step:

1. Oil Sight Glass: On the right-hand side of the engine, you'll find a small window. This is your oil sight glass, used to check the oil level. Remember, the bike must be upright (not on its side stand) for an accurate reading. The lower mark indicates the minimum level.
2. Oil Fill Cap: Typically located on the top of the engine, often near the clutch cover, this is where you pour in new oil.
3. Drain Plug: The main drain plug will be located underneath the engine in the sump. Its exact position can vary slightly, but it's usually either at the bottom back left or at the front in the middle of the engine. You may need to remove part of the exhaust system depending on your bike's setup to gain clear access.
4. Oil Filter: The oil filter on the FJ1200 is somewhat hidden. It's generally found on the left-hand side of the engine, just behind the clutch slave cylinder. You'll identify it by a round alloy cover, often finned, secured by a large bolt and a smaller drain screw just below it. This smaller screw is for draining oil from the filter housing before removing the main cover.

Step-by-Step Oil and Filter Replacement

Follow these steps carefully to ensure a successful oil and filter change:

1. Warm Up the Engine (Briefly)

Run the engine for a few minutes (3-5 minutes) to warm the oil. Warm oil drains more thoroughly, carrying away more contaminants. Be cautious, as the engine and exhaust will be hot.

2. Position the Bike and Drain Pan

Place your FJ1200 on its centre stand on a level surface. Position the oil drain pan directly beneath the engine's main drain plug. Ensure the pan is large enough to hold over 3.5 litres of oil.

3. Drain the Old Oil

Using the correct size socket, carefully loosen and remove the main drain plug from the sump. Be prepared for the oil to come out quickly. Allow ample time for all the old oil to drain completely. While it's draining, inspect the drain plug and its washer. It’s always good practice to replace the drain plug washer with a new one to ensure a leak-free seal.

4. Drain and Remove the Oil Filter

Once the main oil flow has slowed, move your drain pan under the oil filter housing. First, carefully loosen and remove the small drain screw located below the main filter cover. This will allow oil from the filter housing to drain. Once drained, remove the larger bolts securing the filter cover. Be extremely careful with these bolts, as they can be prone to rounding off if the wrong type of socket (e.g., 12-point instead of 6-point) or excessive force is used. Remove the cover and pull out the old oil filter element. Clean the filter housing thoroughly with a clean rag, ensuring no debris remains.

5. Install the New Oil Filter

Insert the new oil filter element into the clean housing. If you have a new rubber sealant ring (O-ring) for the filter cover, now is the time to replace the old one. Apply a thin film of fresh oil to the new O-ring before installation. Carefully refit the filter cover, ensuring it seats correctly. Reinstall the bolts and the small drain screw. Consult your Clymer or Haynes manual for the correct torque specifications for these bolts. Using a torque wrench here is crucial to prevent overtightening, which can strip threads or damage the housing.

6. Reinstall the Drain Plug

With the new drain plug washer in place, carefully thread the drain plug back into the sump by hand. Ensure it starts cleanly and doesn't cross-thread. Once finger-tight, use your torque wrench to tighten it to the manufacturer's specified torque. Again, consult your manual – overtightening can strip threads, leading to costly repairs.

7. Refill with Fresh Oil

Using a funnel, slowly pour the recommended amount of fresh engine oil into the fill cap opening on top of the engine. For an oil and filter change, you will need approximately 3.35 litres of oil. For an oil-only change, it's closer to 3 litres. Be sure to use a good quality motorcycle-specific oil. Many FJ1200 owners recommend a 20W/50 grade oil, with "Morris Ring Free" being a popular choice among enthusiasts for its suitability for older, air-cooled engines.

8. Check the Oil Level

After pouring in the oil, wait a few minutes for it to settle. Then, with the bike upright and level (on its centre stand), check the oil level through the sight glass. The oil level should be between the upper and lower marks. If it's too low, add a small amount and recheck. If it's too high, you'll need to drain a small amount.

9. Start the Engine and Recheck

Start the engine and let it idle for a minute or two. This allows the new oil to circulate throughout the engine and fill the new filter. Turn off the engine, wait another few minutes for the oil to settle, and recheck the level in the sight glass. Adjust as necessary. Also, visually inspect around the drain plug and filter cover for any leaks.

Choosing the Right Oil for Your FJ1200

Selecting the correct oil is vital for your FJ1200's longevity. Given its age and design, a robust oil is recommended. Here's a general guide:

For the FJ1200, a good quality 20W/50 mineral or semi-synthetic motorcycle-specific oil is generally an excellent choice, particularly one designed for air-cooled engines. The "Morris Ring Free" 20/50 grade mentioned by FJ owners is a testament to this preference, known for its protective qualities.
