1600 classic 2006 noise coming from front wheel drives me crazy. At first thought was cam chain tension but after ride test tech said it,s not from the motor, so is something that when in motion at 30mph start whamming.It,s not wharp disc cause there's no vibration while breaking. I notice calipers have some kind of play.It's this suppose to be like that? maybe thats the problem or maybe the bearings or the shaft.Front tire it's new, and this is something going on for a while but more noticeabla later. Help:-o
