Just an update. Rear suspension has been changed under warranty twice because adjuster ring is seizing, Tyres still only last 6000k (3728 miles) at best. Drive belt still whines. I have avoided the rear suspension failing again by not carrying a pillion. No response from HD Australia. Dealer just talks shit. Ho Hum.
Low blow Pauly.
Where are you living Dave? I may know a decent race shop that can properly assess your bike. It has a frame issue by the sound of it.
I think its the over the top large tyres fitted std . I have ridden a few of the new Fat Boys and they handle like a Coles trolly!
Whining drive belt is a sign of it being too tight.
Has the belt tension been checked?
