Thank you to all who offered help ... The links Agusta sent were 3x over the limit set by them , but now they are saying that they are changing the figures and the parts now pass !! As I feel uneasy about this I am getting the workshop to reduce the tightness down to Agusta, s limits ( as set in their manual ) . All a bit strange and slightly worrying !! If you see a 109 going around in circles , you will know what's happened .....
