Before I embark on a major diagnostics session , my 04 16,000km ABS has developed a significant vibration when going at sppeds greater than 110mph, anyone else encountered this? I have newish BT020 tyres (with ultraseal in them), head bearings are OK as are wheel bearings. The main recent change is the addition of v-strom hand guards which maybe upsetting the airflow. Will rip them off at some stage to test theory but if anyone else has them fitted and no vibration would be good to hear it so I can maybe discount it and look for another cause
