The oil change kit...new oil filter, 2.5 qts of Polaris synthetic oil is $41.99
Then you need to spend another $1 and get a new engine drain plug copper compression washer.
And when you do the first service...not the service hour display on the instrument cluster...at first service its counting down from 25 hours. So take a pic of the hour meter, print it out and staple it to the receipt for the oil change kit. Keep these in your "warranty" file...just in case...you can document when you did it.
This is the documentation my dealer told me to keep...as I bought the Polaris 5 year warranty.
