Can anyone tell me what it means if oil is coming out of the air filter? I just got the oil changed last week and had no problems. I havent rode the bike for a couple of days and went to pull it out and saw oil leaking out of the air filter. I put less then 200miles on the bike since the oil change. I am hoping that maybe the dealer over filled or something very simple but fear the worst......

 

Sounds like they overfilled it, if they are new and weren't paying attention, the manual says that a dry fill will take 3qts. Most oil changes are wet changes, meaning there's still some oil in the system even after the pan is drained, if this is the case it should only take 2.5qts. Just a guess...

 

OK, not 100% sure how oil could be coming out of your air filter since it is unrelated to oil...now if you said gas I'd understand. Maybe you're getting blowback off the top rockers themselves. Check around your rocker covers and see if there is any oil leakage anywhere. Your air filter is part of the fuel system, hence no oil would be coming through it. Are you sure it isn't dirty fuel?

 

There is an umbrella valve in the rocker boxes of both cylinders these are supposed to act as check valves and just let oil vapors pass out of the heads thru two little hoses and vented into the throttle bore to be burnt in the combustion process. A crude closed emissions control. Check your oil level when the bike is at operating temps if its overfilled let the dealer adjust the quantity. I have open air filters on both bikes, one has 33k on it and no problems the other at 8k and no problems.

 

Too much oil, plain and simple. The proper way is to add about 2.5 quarts and run it for a few minutes and then check the level. If it is halfway or so ride it for a while and check it again. Once bike is at regular operating temp fill to the top if you wish.

 

this is completely untrue...your cylinder head crankcase breathers run though your intake (crankcase breathers).... alot of people will actually re-route then to a catch can or something along those lines to catch that oil before it gets into your intake and sucked back into the motor... before i go on long trips i will use a turkey baster to remove a bit of oil to compensate for the oil expansion as it gets hot... you will find alot of people do this... just pull a bit of oil out you just have a touch to much in there...

 

^^^Incorrect answer.

^^^Correct answer and procedure.

 

It's a common problem and has nothing to do with overfilling. Here's the cure.

since removing the baffles I also richened up the fuel mixture...It was too rich so today I readjusted the needle...there was excess oil accumulated more so than before. I thought that was interesting as not a single drop of oil has been added since change a while back...

 

Thank you for your replys I am feeling a little better about it now... Still pissed thou.. It was my 1st oil change and spent way to much at the dealer to get it done for them to F*** it up
