Honda Spada VT250 (1989) Front end is making a horrible whining noise. It started when i was slowing down at traffic lights but sometimes it continues as i'm riding and the sound gets higher pitched at I go faster up until it either goes away or i can't hear it anymore at about 60-80km/hr. If i slow down to walking speed it stops. Don't think its the brakes because it makes no different to the noise when i apply and release the front brake. Don't think its from the engine because changing gears doesn't effect it in any way. I though it might be the front wheel bearings but i got the front wheel off the ground and slowly rotated it and it is smooth and quiet and has no side to side movement. Spinning the wheel with my hand i couldn't get it to make the noise. Any Ideas?
