Put stereo on in garage
Removed fairing lowers to fit Stebel Magnum Horn
Swore at original horn bracket mounting bolt which was seized solid

.
Adapted existing bracket to take new horn.
Fitted horn (should give the MOT man a nice surprise

)
Struggled to get plastic pop rivets out to refit fairing lowers using screwdriver
Extracted screwdriver from palm of my hand
Raided first aid box for antiseptic wipes and dressing
Had a cup of tea and put bike away - oil change can wait till next week now.
