I did a search. If this has been covered, my apologies.

I changed the oil, burped it, rode around the block and...........

oil is pissing out of the frame plug. Do I just need a new crush washer or is it something more sinister?

If it is just the crush washer, can I go to any parts house and match it? OR, do I need to buy the KTM one.

Cheers

Go match it, buy a few for your tool box, happened to me before.

Did the oil change. Put in the required 0.6l, and startedup the bike, but no oil coming out of the plug. What now?

I'm kind of feeling that you rushed into this.....take it slower....

So, you poured 0,6 L of oil into the frame and you poured 1,3 L into the crankcase, right?

Then you went to burp the frame. You started the bike. The bolt on the frame should just be just half a thread in. Put a rag underneath it. When I change oil and filters it sometimes takes like 30 or more seconds for the oil to start coming out. Sometimes I need to remove the bolt completely and wait for the oil to start coming out. If I remove the bolt, when the oil starts coming out, I shut off the engine, thread the bolt completely in. Wipe the oil that poured out and do it again, this time not removing the bolt completely. When oil starts seeping around the threads I call it good.

I did exactly what you said here. But no oil Coming out. Maybe I didn't put enough oil in.

Did you give it 30 seconds or so of run time? Did you fill the spin on filter with oil?

[Retromountainrider]

Wait. I got it figured out! Thanks for your help :). Appreciate it.

Yesterday when I fired up the engine I didn't get any oil coming out of the frame, this morning when I started the engine the oil came right out. Weird, I wonder what changed. Both times I let the bike run for the same amount of time.

Air came up as it is lighter than oil....I reckon....

In future, just run the bike until oil comes out, no biggie!

And I guess that would be why we bleed the system ;).
Thanks for your advice guys. I'm very new to duel sports and working on bikes in general. Always good to know people are willing to help on ADV rider.

Additional information as of 05-07-06
After discussing the options, it's possible that the best way to burp the frame on an '02 and earlier 640 would be to install the filler bolt loosely in the frame, in other words, threaded in, but not quite all the way, then start the bike and wait for the oil to flow out past the threads. As soon as you see the oil, tighten the bolt... then shut off the engine.
Have a rag or two handy to soak up the oil that slides past... but if your quick about it, there should be a minimum of mess.
Truth be told, it may actually be the best way to do it on any year, as the hose trick is a little on the fiddly side of life

I too am guilty of not re-reading threads from time to time... and I've been bit worse than oil on the ceiling of the garage!
