With these XT's you need to take the bike for a small ride after the 2.6 L & get the motor to operating temperature then read the dip stick level & adjust the oil level accordingly. The XT600 has a dry sump & needs to equalize the oil levels between the oil tanl & sump that is why a ride is nessary.

As mentioned many times I filled my XT oil differently to what Yamaha say. I measure out 2.9L of oil, fill the main tank until the oil level shows fill on the dip stick then poor the rest of the 2.0L of oil into the motor throught the engine breather hose. When I start the bike it will show the correct oil level quicker then doing it Yamaha's way.

Reviving old thread.

I had a local workshop do some maintenance on the bike, and they replaced the oil/filter at the same time actually by "mistake", although i didn't order it. Didn't have to pay for it, so all good.

I finalized the other service tasks this weekend and started up the bike. Put it on center stand, ran it on idle for ~2 minutes, gave it a few small rev increments as i had changed the coolant earlier. Ran it fairly hot for about ~5 min. Thought i heard a ticking sound, turned it of. Checked the oil level, and a small stream pored out as i removed the oil dip stick. WTF! It was overfilled! The workshop apparently didn't check the oil properly, probably cold and/or on side stand.

I extracted out about 100-300 ml. I actually don�t know how much, as some pored out on the bike itself and the rest was pumped out in the oil bin.

The workshop did test drive the bike, although i reckon it was a very short one.

No signs of oil in air box. No signs of oil leaks on engine gaskets. Coolant level went down, but thats rather a an effect of the coolant change. Haven't ran the bike since.

Should I be worried?

No. Not if it's hardly been run/ridden whilst overfilled. If you check again (300ml sounds about right to remove) and the level is fine, then you'll be good to go...
