Drain the Engine Oil:
1. With the ATV on level ground, start the engine and let it idle for 3-5 minutes.
2. Stop the engine, place an oil drain pan under the oil tank and crankcase. Remove the oil filler cap/dipstick, the drain bolt on the oil tank and drain bolt on the left crankcase.



Install a New Engine Oil Filter:
1. Remove the oil filter cover by removing the bolts. Let the remaining oil drain out. Discard the oil filter (3) in an approved manner (see "You & the Environment" below).
2. Check that the oil filter cover O-ring is in good condition and then install a new oil filter. Use only the Honda genuine oil filter or a filter of equivalent quality specified for your model. Using the wrong Honda filter or a non-Honda filter which is not of equivalent quality may cause engine damage.
3. Reposition the spring to the engine crankcase and install a new oil filter with the rubber seal facing out, away from the engine. You will see the "OUTSIDE (TOWARDS FILTER COVER)" mark on the filter body, near the seal.



Add Engine Oil:
1. After the oil has drained, make sure the sealing washers on the drain bolts are in good condition. If necessary, replace the sealing washers.
2. Reinstall the drain bolts and tighten to the specified torque:
Oil tank drain bolt:
14 lbf-ft (20 N-m, 2.0 kgf-m)
Crankcase drain bolt:
18 lbf-ft (25 N-m, 2.5 kgf-m)
3. Fill the oil tank with the recommended grade oil approximately:
1.8 US qt (1.7 L)
4. Reinstall the oil filler cap/dipstick
5. Start the engine and let it idle for 3-5 minutes.
6. Stop the engine, wait 2-3 minutes and check the oil level. Make sure the oil is between the UPPER and LOWER level marks on the oil filler cap/dipstick. If necessary, add more oil but do not overfill.
7. Reinstall the oil filler cap/dipstick.
8. Check for oil leaks.

how critical are the torque specs. I dont have a torque wrench...do I need to buy one? Does walmart have them? There isn't any hardware stores in the town where I am currently, but I need to do an oil change.

if your expierianced enough just tighten it till its snug but be cautious there made to strip so you dont harm inner engine stuff also you need to replace the oil filter each change? how much does a 400ex filter cost?

Fram are $4 at wal-mart. Some people are skeptical about fram though, but I use them and they work fine.

You don't need a torque wrench. Just to were they are tight.
