Where do you add oil?
I put a new filter on and drained the tank ahead of the motor, found the crank case drain.
Don't see where to add to crank case???

 

2 quarts right in the oil tank. After cranking up for a couple minutes kill the engine and check oil level on the dip stick. Here's a good cheap manual that can answer a lot of questions on repairs and service.1999 Polaris Sportsman 335 Service Manual PDF Download This is a dry sump engine and most of the oil except around 8 ounces or so stays in the tank as it circulates.

 

Thanks a bunch
