Hey everyone, My 2007 YZ 450 has been a awesome bike, starts easy, hot or cold, has never given any problems, just routine maintenance. Considering I about to turn 60, casual trail is about all I do now. I do have a lot of MX experience for the 70's/early80's. So I ran across a 2013 YZ 450 that appears to have very low hours, my question is, are there any known problems or anything odd inherited to that year model I should be aware of? The owner did say something about a after market slip on and Wesco( spelling?) Tuner would be included. Thanks in advance for the information.
