I'm thinking 4 or 5 batteries, depending on how many fit. looks to have a ton of room.
Once you get the bike and get it stripped down you can start measuring. Once you know how big she is then you can decide what batteries and how many you can squeeze in there. Jeff's is a nice one and Ben has a good conversion too: http://www.ben.cbccinc.com/BEM/BEM.htm
How hard is it to get rear sprockets?
I had mine made by Azusa Engineering. I sent in my original rear sprocket so they could match the hole pattern and they nailed it. If you go with them you might want to ask them to store the hole pattern in the computer so you (and people who come after you) can simply call and have a new one made. I assumed they'd save it but they didn't. So, anyone wanting a CBR rear is gonna have to send in an original again. Sigh.
