Where is my oil

2002 650 about 300km's since rebuild.

put 900 ml in 50km later only 600 came out. The only thing I can think of is the oil getting past the rings and getting burnt. But there should be blue smoke? Wich there is not.

Any other ways to loose oil (except a leak offcourse ), any test I can do? Or should I just split the cases and have a look?

Don't know if it's of any importance but I'm still using mineral oil for the break in, switching to proper oil now.

Regards, Christof.

Very weird..
Wasn't your engine using oil before (and so it got broke?)

Some volume may remain be in the transmission cover, filter and cylinder head. You will loose some oil, passing the piston rings, but also through the crank case vent.

From you avatar I see that the next generation seems to be secured. A "minibasterd" I persume! :wink:

Christof,

check Weeds Gallery (Page 8) - you´ll see, that about 200ml stay in the crankcase ->
guess the other 100ml got burned.

She had fun 'helping' me all afternoon, mom on the otherhand wasn't so happy when she saw the state of her clothes



Just to avoid confusion, this was not the first oil change, it was the fifth or sixth (been changing oil a lot to get rid of all the leftovers from te rebuild). So if there is always 200ml left in the cases, there should still be 900 that comes out?

Anyone else have this type of mysterious oil vanishing problem?

Yep correct, but nearly everything on the "combustion" side of the engine was changed. I even sent my piston along with the cylinder sleeve when I got it replated so they could measure it, and then get the sleeve to the perfect bore.
Only other thing I can think of is the valve stem seals. I'll take the rocker cover off this weekend and have a look inside.

Christof,

If you don't kick your bike throught several times rigorously after the oil has drained out, the oil in the area under the crank will still be there.

So, after all oil is drained out, hold the kill button down and kick it through several times and you will be surprised how much more oil comes out of the oil drain. In fact, on my 94, I had another drain plug installed in the crank area so I could get all of the oil out. It was pretty surprising how much oil was left in that area.

Do you still have the stock breather tube? On my 01 it was a single breather tube with no foam in it. My 04 was a 2 into 1 breather system with a piece of that large celled foam in the big end. I can see that yours is a 1 into 1 breather set up, if you are just using a piece of 5/8" heater hose that will put alot more oil vapor into your air box.

Like another poster said, if you rev the bike a lot some oil will be consumed through the engine breather due to the vaporization of the oil. There was a tech bulletin that came out a while back from Husaberg and they indicated that when cold and on level ground the oil level should just barely show in the bottom of the sight glass look in this thread http://www.husaberg.org/index.php?name= ... pic&t=7118 and look for tholen's post, it shows the tech bulletin. There are performance gains to be had concerning this oil level as well. On my bike this oil level works out to about 800-850cc's.

So, withe the tech bulletin in mind, add your 900 cc's of oil and see how it looks on the sight glass after several minutes and adjust accordingly with a irrigation syringe and a piece of tubing. As Taffy would say, it's easy peasy....

Hope this helps

Forget trying to measure the amount removed. Is the level low in the window?
Is there any oil in the airbox? The 650 will push oil through the crankcase vent hose at high speeds. Make sure the foam is in the vent hose to help reduce high speed consumption.

@ DaleO, mine is the 1 into 1 breather thingie, there is foam in there. Next oil change I'll give it a couple of good kicks to get the oil out from the crank area.
Bike is a supermoto so it's revved high a lot.


@ Berger, there was a little oil in the rubber inlet boot for the carb, haven't checked the air box.

I'll play around with it this weekend (weather permitting) and keep you guys updated, thanks for the replies, they relaxed me a lot, I tought I did something major wrong during my rebuild, but now it seems to be normal this oil 'consumption'

Had another ride today, around 50km's. Changed the oil afterwards and got 700ml now. Did give it a good couple of kicks while draining the oil, but not much more came out maybe 50ml.

Is it possible to get all the oil out kicking it, or is there just a portion that always stays there no mather what you do?

Again, the question is.....where is the oil level in the window before you start the ride and where is it after the ride.

If these bikes are rode for extended time at high rpm, oil will be scavenged from the vent system into the intake especially if over filled. Some have suggested on filling the bike with 900cc of oil. I personally use a US quart (about 950cc).
If you use the thought that "hey, Im using oil, maybe I should put alittle extra in" you will incure a consumption issue. It will purge the overfill at high rpm's through the vent system.

I have never had this issue, this is just info I have gotten off the site.

Sorry, must've missed your original question. I'm putting in 900ml of oil, and then it just reached the bottom of the oil level window. After a ride I can't see it anymore. When the engine is running I can see it splashing around.


Worst case scenario: the engine is actually using oil, where can it go except past the rings or through the valve stem seals? Any other ways of oil dissapearing?

put a padlock on the oil filler cap :dontknow: (that kid looked a little shifty)
you say you can't see it on the window after a ride. if you tilt the bike to the left, how far before you see it? what happens after you let it sit for 15 minutes? you more than likely have blow by due to the fact that the rings have not seated and you run high rpms.

Well she is my offspring, so anything shiny wich is not firmly attached to something goes in the pocket

Broke it in following this guys advice http://www.mototuneusa.com/break_in_secrets.htm

Only have to tilt it slightly to see the oil. No change if I just let it sit.

well, like mototuneusa says:

Warning:
This is a very controversial topic !!

i'm still betting on blow by. remove the breather hose and cover the frame with tape or something. replace the stock hose with a piece of hose that you can run to an external catch can and see if that's where your oil ends up.

My oil level is usually 2/3rds to 7/8's up the site glass after an oil change.

Berger, does your weep hole leak oil when you ride?

I run it at the bottom of the sight glass per the tech buletin and dealers advice, once i did this, no weep hole leak.

someone else may correct me here, but aside from the breater in the cyl head cover, isn't there a black tume in with the carb overflow tubes which vents the lower portion of the cases and allows pressure compensation with the 'pumping' of the piston, if the oil level is high, maybe you are losing some here, but if you ride su-mo, you should be picking that up in your catch can, but maybe interspersed with fuel and coolant?
