I check to see wear the oil leave was on the dip stick and it was in between the two marks. i took the case plug out and it drian a lot. when i went to drain the frame only a few drops came out. I thought i keep the oil in the frame when it was not running?

I usually get half out of the drain plug and the other half out of the frame. Not sure why you got nothing out of the frame.

Did you run the bike for a minute before you drained the oil? If not, that's why...SC

Correct, always drain the oil when the engine is warm. :banghead:

You're probaly fine to refill with just under 1 liter. Make sure you do your filter too since you won't be getting all the oil out. I'd put in 750ml and then check the level after running the bike for about 30 seconds. I'd almost guarantee that you'll be in operating range, and then you can add a bit more to top it off...SC

Before you change your oil start and run your bike for a couple of minutes. You don't have the get it hot just get the oil circulating through the engine.

Shut it down and wait a minute or two. Open the filler/dipstick. Then pull the frame drain plug. Let it drain for a couple of minutes. Then pull the engine drain plug give it a couple of minutes to drain as well. Then pull the filter and clean or replace. Make sure all drain plugs are in place and that the filter is properly re-installed and secured.

Add the required amount of oil. I usually put in about a Quart and three quaters of another quart maybe a little less. Then start the bike let it run a minute or so. Stop the engine and give it a minute to rest. Then check the level.

If it's low add a bit then re-start the motor for a minute or so. Stop the motor let it rest mabye a minute and check it again. Repeat this process until the dipstick measures the oil at the proper level.

I might be remembering wrong, but doesn't the manual say to add about 1.25 quarts rather than 1.75? This is for a 03 WR 450.

I think the thread was started by a guy who owns a 02 WR 426.

I don't think the question was for a 03 WR 450.

We don't all ride the 450's.

dont really remember, but probably 3-4 weeks, since I was repairing some damage to the rads

just poured fresh oil in today and I totalled 1,55 quart; a bit below max level...my 400 ranges 1,5-1,7 q, your 426 is probably 1,3-1,5--check the book

I'll go against the flow here and say that running the bike for a few minutes before an oil change is a bad idea. A few minutes isnt long enough to warm the oil. Cold oil is thick. Starting the engine pumps oil up to the head and the crank etc etc. This thick cold oil will not run back to the sump quickly, and hence wont get drained. On the other hand, if you dont start the bike all the oil will be in the bottom of the sump and the bottom of the tank, assuming when you rode the bike last it was up to temperature. I drain the oil tank by the pipe on the Rh side of the engine instead of the frame drain plug. This drains the old oil in the pipe aswell.

Can someone please tell me why everyone seems so concerned about getting every last mill of oil out? Is ten mills left in the engine gunna make two tenths of bugger all difference once mixed up with the new oil?

BTW Hamish I agree with you totally!!! Cold oil for me unless right after a ride.

I TOTALLY agree. I only use the main drain bolt and that gets most of it. With as often as we change oil it seems unnecessary. You will never get it all out, just let it drain a bit longer and you will be surprised how much comes out. Don't really know why Yamaha put all these drain bolts on anyways.
