[QUOTE="FJReady, post: 1457919, member: 465"] Thank you rPgoat and rbent for including your torque numbers. I completed my all balls tapered bearing install yesterday and took a short test ride and was happy with the upgrade. I torqued the first nut to 14ft-lb and I plan to go back in to check it and adjust it after a few hundred 'break in' miles. With your data I won't be afraid to run up to 20-22 ft-lb. On my short test ride, which the bike was not heavily laden with luggage etc I could not induce a wobble in any of the conditions it used to appear. (cruise control at 35-45 mph, deceleration from 50 to 30) so I'm happy about that. At a steady 35 mph and cruise control on, I could induce a wobble by smacking the handle bars. But it wouldn't do it unless provoked. Even hands free over pot holes, etc wouldn't cause a wobble. I need to load up the side cases and top case and see how the bike is then. The installation was no cake walk. Getting old races out was fairly easy. Getting new ones in, especially the lower one on the steering head was a chore. I'm thinking I'll make an installation bushing or something to use when pounding on those suckers if I ever have to do this job again. [/QUOTE]
