how about this.
I drained my oil, filled it with new one up to the maximum. Than started my bike for few min and turn t off. waited about 3-4 min and checked the oil it was on minimum so i added a bit more up to maximum. Again started, waited, stopped, waited and checked the oil and it was at maximum. The next day I made 170km, today chacked the level before the ride (cold engine) and it turns out there is quite a bit too much oil. Bike was in exactly the same position as before.
When i used 10w-40 mineral i never had any problems, now my brake in period is over so i changed it to 20w-50 synthetic and this happened.
Apart from this i noticed that the engine sounds different. Much better now, with the 20w-50, quieter and more natural. Maybe a bit less power on low gears but maybe its just my imagination....

any help please?
