Well done Saaz,
Checked it out and found the 'tab'. Would not have noticed it (well, didn't actually) without your help. It is an 1100 and the air hose was laying under the engine head touching against the heat shield. Even I knew that was not right, but certainly had me bamboozled (when was the last time you heard that word, must be showing my age) as to its right location.
Thank you, one and all.
