I have a brand new 2006 klx110. Sometimes the rear wheel makes a clicking sound. Similar to the sound my Xtreme made when the chain adjusters where messed up and the rear wheel wasn't straight. But my rear wheel is straight! no broken spokes, they all seem tight, but i haven't gotten my spoke wrench yet. The chain is kinda loose but that would matter. It happens alot when i go through this one deep rutted corner.
