07 WR450 oil change

10 posts in this topic

OK, I did my first complete oil change the other day. Filter and all and followed the manual completely.

the manual says a complete oil change with filter will be 1.27 quarts. I ended up with 1.75 quarts of oil to get level to show on dipstick. Went for a quick ride and still on level of dipstick.

Were did the other 1/2 quart go? No overflow, no oil anyplace.

How much oil are you guys adding each complete change?

1 quart. I've changed the oil and filter twice and the oil level has been right on per the dip-stick when warm.

Now I am completely stumped.

I drained the oil from all three drains. Did not touch the filter. The manual calls for adding 1 US quart. I did that and still no level on the dipstick.

Does the bike need to be warmed first for a level to show?

Does you bike show a level after adding oil but not riding?

I do not want to destroy a new engine but want to get it right..

Thanks

Dont read the stick till after you have run it for a couple minutes. One quart is all you should need.

THANKS GUYS!!!!!

That did the trick. Still do not know how starting the bike raised the level but did as you said, added one quart and started the bike. Level came right up to were it belongs.

I am so used to adding oil and checking the level. Someone can explain how this works on the WR450 and then i will know also.

Once again thanks

The 450 uses a dry sump type of system like when the reservoir was in the frame. You have to run the engine until all the oil is pumped into the reservoir so you can measure the oil level. The new reservoir is in the cases on this engine. WR Dave.

!Watch out¡ If you overfilled... oil will come out in the air-box, through the vent hose... I did re-route mine to the chain, and plugged the air box hole.:applause:

Dont forget to do the whole gallery bolt bleed. It's important to make sure you have pressure. Or at least the manual says so.

The dry sump makes sense. Thanks for explaining how the level gets there. Manual should do a better job of explaining to start and then check level.

I will check the airbox tomorrow but think it is OK since did not go for more than a 3 minute ride since changing the oil the other day.

Once again, thanks to all who responded.
