OK searching for a rotor I leave no stone unturned. Wound up finding a 1982 CB900c (with the same rotor). Go look at it...pulled the stator cover and tested it...good!!!!! Wound up buying the whole bike for $100. Just spent an hour getting the old ones out...thank God for PB Blaster!...and a bigger hammer...actually had to use a a 24' pipe wrench on the bad one in the good bike. The real problem was dealing with the crash bar on the right side. Was able to take out the two front bolts and loosen the bottom bolt (nut would not come all the way off as it was hitting the exhaust) to be able to have the stator cover have enough clearance to come off...but the tool I borrowed from the Honda dealer was the star variety like a lug wrench with the various size threads on it. In order to be able to get it into the rotor...the crash bar had to come fully off. Got out the sawzall and shortened that bolt enough to get the crash bar off.
The good rotor tests out at 6.4 ohms but it has a bit of corrosion on it. Can I sand or wire brush it and give it a spray with some polyurethane or something? Or can I just ignore it as 30 year "patina"? I don't want to take a chance that the corrosion will hit the stator...how much clearance is there there anyway?

In 1972 I had to make a choice...quit riding...or quit drinking. God says it's safe to get back in the saddle now...at least I'm still alive...and feel more alive with the wind in my face! Now riding "Helen Black"...1982 CB750SC.
