I have a honda 350 rancher. I opened my air box yesterday and it was nuckle deep of oil why is that?

 

it could be 2 things. either A) the air filter oil dripped out into the air box, sometimes water causes the oil to separate from the filter, or B) you have excess blow-by gasses that are pushing oil through the breather into the air box. I would bet on option A) because that's what mine did.

 

mine's been doing it for months will let you know what i find out, hope u will do the same

what year is your bike?

 

2002 model bought it in 2001 has 600 miles on it.

 

yea, i had a feeling it was a 2002, i being told its some issue with piston rings, im waiting to see whats going on
