Guys:

I was cleaning my '04 sportsman 600 today, and found what seemed to be possibly oil in my airbox. The only way I can figure it got there was thru the breather hose that connects to the airbox. I checked my oil level and it did seem high, not sure why. Anyway, have any of you had this same thing happen, or do you at least have a theory to what might have happened. I'm hoping this isn't a sign of worse things to come. Thanks.

 

have u ever rolled the atv or had it on its side. or even wheelied the atv, this will cause oil to run back into the airbox.

 

that happend to my sportsman400 when my cousin was goin up a hill, stoppped half way, then when he accellerated it wheelied and went over backwards.. all the oil went into the airbox

 

its normal

 

Mine was filling up the drain tube with engine oil. Upon further investigation, I found that crankcase had nearly a gallon of oil inside. Changed oil with new Polaris synthetic and a new Polaris filter and now things seem normal. Should I also change the inline breather filter??? Any ideas??? Do these machines come from the factory with the engine oil inside the crankcase, or is that installed upon arrival at the dealership???

 

I don't think you can fit close to a gallon into the engine.

 

where does a gallon come from. the atv only takes 2 quarts to fill full. atually it takes a little less then 2 quarts

 

I don't know where it came from. All that I know is that the motor oil damn near filled a 1 gallon paint can that I was using to catch the waste oil???? Any ideas????

 

if the paper filter becomes saturated in the airbox,,,,,it needs to be replaced

 

Did the gallon of oil smell of gas? Did it seem to thin? Just a thought........
