the 1987 artic cat jag has a oil tank under the hood that you put 2 cycle oil in. then when the sled is running it injects its oil into the gas . that is if everything is still stock and original
You put the key in & you turn it & it will start.
Locate the petcock under the engine. put a pan under it large enough to hold 5 quarts of oil. open the petcock, open the fill hole at the top of motor and let oil drain out. Remove filter and replace with new one, using a little of the old oil to lubricate the seal ring on the oil filter before screwing it on. Once oil has drained, replace petcock and fill engine with new oil using the amount of oil recommended for the year and motor size of your arctic cat. The 2001 400 4x4 Arctic Cat takes 4.75 quarts of 10-40W motor oil. Replace the fill hole cap , start the ATV to circulate the oil and make sure no leaks. Dispose of the old oil properly.
