I can't remove the spacer and I can't progress any further until it is gone. How can I remove the...

Iain's TTR as developed a clinking sound on the mono shock on rebound only? We checked all the bushes and can feel no movement. It doesn't make a sound when pressing down, only a click on return? Just wondered if anybody else had this problem. Otherwise both bikes running well.
