IS she running once again Paul???
Apart from the Haynes, I've never found a specific manual for the 600ss - I think youve downloaded a manual for the 750/900 from here:
http://www.duc.nu/manuals/ Rear axle torque for my 900ss - 52 to 56 lbf/ft
If you have a tapered spacer it apparently needs to be fitted with the angled side facing in towards the wheel centre.
Good luck - Frank
ps - was it you that changed the rear wheel bearings??? If so and you still have probs, it might be that the bearing are not seated properly in some way.
