I just bought 2012 YZ250F. Other than a stripped out oil drain plug, it looks like its been treated decent. I have been out of ATV's and dirt bike's for over 20 years so Im curious as to what and when i need to be doing regular maintenance. Is there a thread on here already with recommended maintenance and schedules? I know what the book says, but am curious what happens in the real world. Any help would be appreciated.
