"I've heard anecdotal evidence about the much improved handling after installing tapers, but a lot of that could be the result of simply going from old, dried up bearings & peened races to new bearings, not just the change from balls to tapers. "

I agree with this statement wholeheartedly. The stock ball bearings when properly greased, and adjusted, are well suited for the application. The tapered roller bearings are really only necessary when the rake is increased for longer front ends, or high performance applications like racing. However I have installed several sets of tapered roller bearings into the CB 750's and never had any problems with clearance. The first set I installed, I put a spacer on the bottom bearing, and then noticed it was not necessary. I then had to carefully drive the bearing of, and remove the spacer. Since then I have never installed a spacer on any of them. If you do a search for "POW-MIA" it will bring up a thread where I show the installation of tapered roller bearings.
As for reusing the ball bearings, I have done this on several bikes. I just clean the bearings and races, then inspect them for wear/damage. If everything looks good, I grease them up, and install them.
