gave the mighty thou a clean this morning and decided to look at the exup valve to see if i could find the rattle...everything came apart easy thanks to the copper grease and stainless bolts i fitted in the spring 
...re-assembled using copper grease and checked tension of the cables...all fine as i expected as i had adjusted in the spring...so every thing back together and give it a go.......rattle still there :\ ....just at 2000 rpm....its diffacult to hold the throttle at 2000 and get down low enough to hear where its coming from so...i removed the valve again and held a bit of hard foam over the hole and started it up....rattle still there,so not the valve :rolleyes .....thought i check the top of the down pipes where they pass under the engine to see if any stones were rattling about under there...no stones but i did find this................
no not the 50p :rolleyes :rolleyes .....the metal spacer,started it up and all nice and quiet
......so,my next question.........where does the spacer go ......looks like engine mounting spacer but cant see any missing :\
