rode into work this morning, suddenly, just before the underground car park, a shrieking noise, as if I'd engaged the starter on the running engine, but very regular sound, no crunching, so to speak.
Sound frequency was linked to engine rev's, so definitely not the drive train.
I have been told that if you travel in France with loud (asbo) exhausts and are pulled over your bike can be impounded until you sort out the exhausts noise. My bike has aftermarket exhausts fitted. They have a BSA number etched into the chrome.
Has anyone had experience of this?
