Every time ive changed oil on a bike, checked the oil level, run the bike and checked again, the level is lower, not higher. I guess i should ask the boneheaded question: was it on the same level surface both times it was checked? On the center stand both times?
Absolutely, same level surface (100% level), all times on centerstand. But you are right to ask. Mistakes can be made, even the most silly ones.

To get down to the normal level I took 500ml out via the oil filler hole with a thin fuel pipe (from model aircraft days) and a syringe, took a while but its possible.
I would guess as has been said earlier maybe you didn't drain all the oil out but don't worry as dealers do the same sometimes due to time or letting the apprentice change oils.
Now when I change the oil I don't go by quantity I just keep slowly pouring in until the desired level is reached.
After engine and oil warm up, I opened the drain screw, let it drain for 15 minutes. What else could one do to get "more" out ?

To complete the procedure I started the engine briefly after filling in the first 3 liters, waited, and kept filling. Still don't know how the recomm oil quantity can be SOOO wrong ...
So tonight I started the messy draining of excess oil, through the drain bolt. Kept it in place so I could screw it back in without delay and control the amount of oil drained. After 200ml / almost one quart drained the level window showed max. This is truely amazing. If I run the numbers again, and if you're interested , here is the result:
- book value for oil change w/o filter 3.8L
- from new drum 4L
- filled in 4L minus 450ml = 3.55 L, which resulted in
- oil level window completely filled with oil, even after a few minutes ride and waiting 5 minutes
- removed another 200ml (tonight) and now the window shows max. allowed
- total amount left in my engine : ~ 3.35 L or 450 ml under spec.
No wonder some dealers return overfilled engines.
Why have I drained excess oil through the drain bolt and not the filter ? Not sure the oil filter gasket can / should be used a second time after
the oil filter has been on for many heat cycles. The brand new gasket on the drain bolt I could not replace either (wanted most of the new oil in the engine to stay there). But by increasing the torque on the bolt by 10% I think the drain will be tight for the coming 12 months.
To compare the numbers, I would much appreciate if some one could accurately measure how much oil he has to fill into his engine next time, and report it under this thread.
