It’s not that easy to access the oil pump and lines on the rev I bought an 2006 had major oil leak turned out a bolt on the side of the oil pump was missing. To even see it you have to take the secondary off then the air box,remove carbs then you have to remove the motor mount bolts so you can tilt the motor towards the front of the sled then you can get at the oil pump and lines these are not the best sleds to work on good luck
