So the battery on the cbr is probably shot, but just to confirm, I wanted to get it load tested at Autozone. Took it in, and they threw the load testing on it, but as I expected, it didn't have enough charge to test. I had them put in on their trickle charger and stopped by this afternoon to have them do the load test now that it was fully charged. The manager there said he couldn't load test it because "it would harm the battery" as the testing was sized for car batteries and would overly discharge a motorcycle battery.

Has anyone else experienced this? They can set the resistance of the load tester (corresponding to the rated battery cranking amps) to whatever they want. I couldn't see how a motorcycle battery is any more likely to be damaged than a car battery if you've set what you want it tested at correctly. Since it's not worth arguing with the guys there, I'll just do an in bike test, but I don't expect a whole lot from a battery manufactured in '03.
