I have purchased a new honda atv recon es. As I was getting ready to take it out the door the sales persons mentioned a 20 hr tune up needed for the atv at a cost of $180 with replacment parts extra. Now I know I have 6 month warranty, that is standard for Honda ATV. Can anyone shed some light as to what this 20 hr service thing really is. I'm new to ATV's so this was my first purchase and love the ATV. Any information is greatly appreciated..
