Hey guys I'm new to this forum, so if my question is in the wrong place I apologize. My dad has a 08 KLR with 7000 miles we just done the doohickey with the torsion spring but the valves sound a little loud. What shim sizes should I buy before taking it apart? Or should I buy a kit? If so which one would you recommend? I'd love to have the correct size when I tear into it. Thanks so much for any help!
