Mac is right as well, make sure you are using the proper amount of oil, and not overfilling.
after draining the oil in the bike the manual says to add exactly one quart without an oil filter change. the bike had the right amount of oil. i can feel a mist of oil coming from the breather tube when the bike ir running and it drips a fair amount of oil for a couple minutes after it is shut off. i am not sure how many hours are on the bike i was told it was recently rebuilt. maybe he lied or maybe he put it together wrong. i am going to check the compression but i am pretty sure it needs a top end rebuild.
I would give it a ride or two before you rebuild the top end
as 4lr said there is a certain amount of oil that will froth up and end up coming out of the breather under certain conditions.
(maybe more if the bike runs inverted at any length) possibly exacerbated if you let the bike run after a get off or just frequent crashing LOL
unless you are actually seeing a constant "mist" coming out I would not give up hope that it is not just the remnant of the Possible original overfill problem.
btw you said you can feel oil mist coming out while running , can you see it on your hand or a paper plate?
let me be clear My 07450 and my08 250 do and did the exact same thing all the time new and with some seasons on them.
this is normal to an extent.
you can expect if you put your hand under the tube while running some gasses and pulsating air flow will occur. depending on conditions, frequency of rides, type of oil , and duration of run time this may be completely normal.
a huge puddle under the bike is not normal, but there are reasons this could be caused by things other than what has been speculated.
in fact the puddle under the bike (while sitting) actually leads me to believe it is not a blow by situation.
my guesses for possibly having too much oil in the bike are :
not draining all the oil out , caused sometimes by not knowing there are several places you are supposed to drain the oil from and an actual procedure for draining the oil. which is also important in filling -
the owners manual require a certain protocol that must be followed when checking the amount of oil on the dipstick or the reading is completely inaccurate.
so what I do is measure and then follow the manuals procedure to make sure there is little room for human error.
you could see where adding a quart of oil to a bike when not getting all the old oil out could cause there to be too much in the cc.
