in the spirit of ATV questions like this one https://glocktalk.com/forums/showthread.php?t=1181530 I have one too...I have a 2008 Honda Rancher 420FE that just hit 20 hours. The manual says to take it in to the shop for an oil change and for them to check the valves. I called, and was told that a valve adjustment and oil change would run nearly $400! The tech told me that if the valves really need to be adjusted I would hear that they were off. I don't hear any clicking or anything so I assume they can wait (the tech said he does his at 200 hours unless they sound bad). Where can I find instructions on changing the oil? Where can I get a filter? If I do it myself how do I reset the oil change warning signal? Do any of you have any sites or references that can help me out? I am not very mechanically inclined; but I have managed to do all of the maintenance on my John Deere X300 without any help. Also, are there any other things I need to check while I am at it? Your help is always appreciated.
