Horrible Noise Under Acceleration.

[darrsi]

Just a suggestion, but needs care and two people when doing it.Try simulating acceleration with the bike of the centre stand foot on the brake and bike in whatever gear it sounds worse in open the throttle a bit that will put pressure on the bearing and allow you to locate wher the noise is coming from.Anytime i have had to do this it is on a lift tied down

If you're gonna do this it might be worth seeing if the noise can be recorded in case it becomes obvious to the right ears.
Maybe put a video on YouTube so it can be viewed and listened to if you manage to recreate the sound.
