WR250R Oil Change

Yamaha recommends changing the engine oil on the WR250R every 3,000 miles, and the oil filter at 6,000 miles. It is a quick process and should only take 15 minutes. Yamaha recommends using one of the following oils: YAMALUBE 4, SAE 10W-30 or SAE 20W-40.

I’ve been using 10W40 in mine. I change my oil filter every time I change the oil.

Tools I used:

• socket wrench
• 8mm socket
• 10mm socket (to remove skid plate)
• 12mm socket
• oil catch pan
• 1.3L – 1.4L of Motorcycle Oil
• Oil Filter KN-141
• O-Ring for oil filter cover (optional)
• Crush washer for oil drain bolt (optional)
• torque wrench (optional)
• funnel (optional)
• gloves (optional)
• wood scraps or a dirt bike lift (optional)

Consumables:

1) Run the engine for a few minutes. Warm oil flows better than cold.

2) Put the motorcycle on a dirt bike lift to keep it vertical.

Since I’ve lowered mine with a yamalink, it doesn’t quite fit on the stand. I used a couple scraps of wood under the kick stand instead.

3) position the oil drain pan under the motorcycle.

4) If you have a skid plate like my Thumpertalk skidplate, use the 10mm socket and wrench to remove it. If you don’t have a skidplate, skip to #5.

It does have a hole to allow draining, but I’ve found it makes a mess to leave it on. This is also a great time to clean the inside of the skid plate!

5) With the 12mm socket and wrench, remove the oil drain bolt (red arrow below). The oil may be hot, so be careful not to burn yourself.

6) Remove the oil filler cap to allow the oil to drain out more easily

7) Use the 8mm socket and wrench to remove the three bolts holding the oil filter cover on if also changing the oil filter.

8) Remove the oil filter. Clean the inside and the cover.

 

Be careful not to loose the little o-ring on the top. 

Inspect the oil O-ring for damage and replace if necessary.

9) Install the new filter onto the protrusion and re-attach to the bike. The three cover bolt should be tightened to 10 Nm.

10) After the oil finishes draining, replace the oil drain plug and use a new crush washer if necessary. Tighten the drain bolt to 20 Nm

11) Add 1.3L of oil if not changing the filter or 1.4L with a filter change. I use a funnel to avoid making a mess.

When filling, check the level against the oil sight glass and get it between the two lines.

12) Replace the oil filler cap and run the bike for a minute. Check for leaks around the oil filter cover and the drain bolt.

13) Replace the skid plate if you have one.

14) Go for a ride!

 

PS: yes, I washed my bike after changing the oil.
