New front tyre fitted and now a singing bearing noise present

[Bad bad boy]

I think Bandit may be thinking about the spedo drive - here is my post about mine with lots of other perhaps useful info for you.  http://foc-u.co.uk/index.php/topic,24814.0.html    Many thanks for the help and info I'm not sure if the speedo drive would make this sort of noise it's pretty heavy but will check over thanks Alan
