First professionally maintained says nothing. I am going to state what needs to be addressed and you decide. Many of us have found tight valves , and below the recommended mileage for a valve shim check, my 2015 I did @ 12000 KM approx. half the recommended mileage and I found tight valves. My 07 Versys I did at 27,000 KM and found one exhaust tight to the point I was worried of damage. 12,000 miles I would be doing a valve shim check, one easy way to see if there is a problem is hook up the vacuum gauges and see if the throttle body sync is off ( word of warning, if the owner has adjusted the bypass screw this won't work) here is a video explaining http://www.kawasakiversys.com/forums/1317761-post30.htmlhttps://www.google.com/url?sa=t&source=web&rct=j&url=https://sanantonio.craigslist.org/mcy/d/2008-kawasaki-versys-650/6616352490.html&ved=2ahUKEwiS_Kahs-zbAhVKbK0KHRUjAnsQFjAAegQIABAB&usg=AOvVaw2ZCjHDU4pggvZ7dzSgfKDF
Thanks for the advice! This is the bike I'm looking at. Its about 3 hours from me in San Antonio. If any of you have time, I'd like to hear your thoughts. My biggest problem with it is the tires are from 2013 (rear), and 2014 (front). Other than that it looks like a great bike for its age. Should the age of the tires be a big concern, as well as the overall mileage of this bike at $3250? I was more comfortable at my offer of $3000, but he met me in the middle.
