Oil Service - CBR 1000RR DIY

This DIY article describes how to change oil and oil filter on a 2008 CBR1000RR Honda motorcycle and is to the best of my knowledge also applicable for 2009 and 2010 models.

Time and Tools

This is an easy DIY task. A first timer may spend 2 or 4 hours doing it, an experienced around 40 minutes.

Be patient when fidelling arround with the plastic tabs on the cowls. Honda has made a very clever "snap them together" system, which is easy to dismantle and reassemble if you do it right. Read more about this in the referenced DIY article (see step 2 here below).

Tools needed:

Spare Parts and Consumables:

Note 1:
Honda recommends Honda "4-stroke motorcycle oil" or an equivalent.
API clasification: SG or higher (except oils labled as energi concerving on the circular API service label), viscosity: SAE 10W-30 (or 10W-40 in hot climates), JASO T 309 standard: MA.
I used Castrol Power 1 GPS 4T, SAE 10W-30, API SJ, as recommended by my local Honda dealer Aagesen Motorcykler.


1) Put the bike with warm engine on side stand and place tape over the ignition key hole.

2) Remove the lower cowl - click here for DIY article on this.

3) Remove the screw holding the rear end of the right middle cowl.

With this screw off and the lower cowl removed, the right middle cowl will now be so flexible that you can easily access the oil filter.

4) Remove the oil filler cap.

Now is the time to spread out a good layer of old news papers under the engine to collect spill over in the next step. The rule here is better safe than sorry!

5) Unscrew the oil drain bolt and sealing washer and drain the oil.

Use gloves to protect your skin. Use one or two old plastic containers you have cut open, to collect the oil which will come pooring out as you can see on the picture.

6) Unscrew the oil filter cartridge using the oil filter wrench.

Notice how a long bolt was used to get the wrench separated from the old oil filter.

Be prepared to collect oil spill from the filter when it comes loose.

I ran into some difficulty here: The oil filter would not come loose. Either because it was tightened too much when it was mounted or because the rubber O-ring seal had burned itself stuck to the metal surfaces.

First I used a hammer on the top spanner to get it loose. Then I tried with a pressurized air tool, but this was to much for the oil filter wrench, on which the nut broke off!

Fortunately I learned a good trick many years ago: simply punch a screw driver through the filter and use that to loosen it.

The inner end of the oil filter is easy to access from the right side of the bike. First I punched two small holes in the side of the oil filter with a distance around 8 mm using an awl and a hammer. Then I punched a big flat screw dricer through these two holes and all the way through the filter out on the other side. I did it with a suitable offset from center in order not to hit the center threaded boss on which the filter is mounted. On the left picture here below you can just see the tip of the screw driver has come out on the other side of the oil filter.

Several hard blows on the screw drivers handle with a heavy hammer got the filter loose, and I could then screw it off with a pair of pliers.

Remark: When doing the next oil service at 24.000 km I had repaired my oil filter wrench with a properly welded nut, so it would not once again break under load. Using quite strong hand force was not sufficient, so I used my pressurized air tool which in about one second got the filter loose. If you do not have an air tool simply use a hammer to get enough vibration and torque.

7) Remount the oil drain bolt with sealing washer, Tourge: 30 Nm (3.1 kgfm, 22 lbfft).
Remember to clean the bolt and washer well, and smear both with engine oil before mounting. The old sealing washer may be reused one or two times if in good condition. The washer is made from cobber and will become harder and harder each time it is mounted. Before it gets so hard that it will not seal correctly, it must either be replaced with a new one (or softened by heating it up to glowing temperature and cooled down slowly). Be sure to tighten to the specified tourge.

And "why should I use a new washer?" you might ask. Because the cobber in the old washer has deformed and hardened when the oil drain bolt was mounted. And - if used again - it may be too hard to form a tight oil seal. Furthermore the washer has probably corroded somewhat during use. On the picture below of the old washer , you can clearly see both deformation and corrosion.

8) Check the length of the oil filter mounting boss.
oil_15_small The boss should protude 15.4 - 16.4 mm (0.61 - 0.65 in) from the cranckcase.

The Honda Shop Manual does not specify what to do if the length i incorrect, but from what I can see from the construction, the boss might have come loose when you unscrewed the oil filter, and it might have been screwed partly out of its mounting hole. Simply make sure you get it reinstalled into the correct position (and use thread locking compound).

9) Install a new Oil Filter Cartridge, Tourge: 26 Nm (2.7 kgfm, 19 lbfft).
Before you mount the filter, smear the O-ring and the thread width engine oil. Also fill up the filter cartridge width engine oil and empty out so much that you can mount the filter without spilling oil all over your bike and floor. This oil will reduce the time it takes to for up oil pressure when you start the engine. Be sure to tighten to the specified tourge. In case you don't have a torque spanner, screw it in as hard as you you would be able to by hand-force only without any tool.
The oil filter wrench might get stuck on the oil filter so you can not right away pull it off. If that happens you can get it loose with a few light strokes of a hammer on the edge of the oil filter wrench. The strokes should be in the forward direction.

10) Fill cranckcase with recommended engine oil using a funnel.
First fill up with 2.0 liters. Then repeat filling up with just a small amount and checking if you have reached the correct level.
The level must be measured with the bike in upright position! Unscrew the dipstick, take it out and wipe it clean. Insert it to the point where the thread begins but do not turn it. Take it out and inspect how much up the dipstick it has reached. The level should be somewhere between the two markings on the dipstick.
Important: Be sure not to overfill as this might cause serious damage to the engine.

11) Install the Oil Filler Cap.
Remember to check that the O-ring is in good condition.

12) Cleanup and Check for Oil Leaks.

13) Reinsert Screw in Right Middle Cowl.

14) Remount Lower Cowl - click here for DIY article on this.

15) Check Oil Level following the procedure in the following section.

Oil Level Inspection

Important: Be sure to use the following procedure recommended by Honda for oil level chek as oil level is highly dependant on several factors: engine temperature, correct upright position of bike, time from engine is cut off to doing the measurement.

  1. The engine should be resonably cold (room temperature ~20 degree C).
  2. Start the engine and check that the oil pressure lamp turns off after a few seconds.
    In case you have just changed oil and filter, it may take a little than usual for the oil pressure to build up, especially if the engine is still very warm and therfor running with a lower idle speed. A sligt increase of turn rate may even be needed but be easy on the gas.
  3. Let the engine idle for 2 - 3 minutes.
  4. Stop the engine and wait 2 - 3 minutes.
  5. Hold the bike precisely in upright position
  6. Unscrew and remove the dipstick. Wipe the oil off with a clean cloth.
  7. Insert the dipstick as far as possible without screwing it in, remove it and inspect how much up the dipstick it has reached.
  8. If the oil level is lower than the midpoint between the two markings on the dip stick, then remove the oil filler cap and top up with the recommended engine oil. Repeat this untill the level is above the mid point. Finally reinstall the oil filler cap.
    Important: Do not underfill and do not overfill as either may cause serious damage to the engine.
