hi
ive got a 2002 bonneville with 30000km , and after about 60km i geta nasty sounding grinding noise from the rear end . i have replaced spokets and chain recently but didnt check the swing arm is this the likely culprit
cheers macca

Could be a number of things, but I would take a good look at the rear brake first.

I would agree with Paas on checking the rear brake first. Then I would check for proper rear wheel alignment, chain adjustment and torque on the rear axle.
Finally, I would suspect the rear wheel bearings or maybe an error in re-assembly due to the spacer location on the axle.
Is your cush drive in good shape?
Is it okay "cold", but after 60km it consistently makes the noise?
How long after stopping before it makes the noise again? Overnight? A few hours/minutes?
If feasible, pull over as soon as you notice it and carefully feel around the rear wheel components for abnormal heat.
Let us all know what you find out.
Good Luck!

The bearing in the rear sproket hub give alot of trouble on these bikes

ok i had done a lot of that but kept the initial post short to see what i missed
the alignment was out a bit and the rear axle torque and chain tension was also out
the bearings feel ok after 60km ie not hot and everything feels tight
the noise comes and goes so ill have another go on wednesday and aim for the brake [ which had new pads about 5000 kms ago]
cheers
