strange noise when going past cars and walls

okay well my bike rides fine and its been running normaly sounds like there is abit of noise but then thats normal but when i go past cars walls or anything like that there sounds to be a kind of screechy disk rubbing noise :/
anyone help

 

huh?
so what about when u actually stand next to the bike when its on.. how does it soudn then? u know that could just be the noise rebounding from the objects back to u.....

 

how long you had the gear up kit in for.Only reson i ask is because when i fitted a gear up kit in my sr 50 many moons ago i noticed a noise it turned out to be that the gear up kits are straight cut where as the standard 1s are cut at an angle just a hunch with out riding or seeing hard 2 say keep us up 2 date mate

 

Disc pads rubbing maybe?

 

hmm dunno new pads no gear up now , and its not there when it idles :/

 

its just the noise rebounding. if you could hear it when your stood next to it then it would be more of a problem. Dont worry about it.

 

have you got a number mate? as its not letting me send any messages...

 

case bearings are gone thats what it was and aidan ill get it tomorrow
