tuning
Hi Jeff,
Welcome to the forum and good luck with your Bonnie

I have the FCR's and tuning is similar .
The first thing to do is note where the carbs are currently set up, needle type and position, main jet size, low speed jet, and idle/air screw.
Keep a record of all of your testing and ride results.
Note low, med, and high rpm results of the butt dyno.
The higher gears will give you a better idea of the fuel mixutre, as the engine will stay in an rpm range longer.
Basically if the engine is popping or stuttering the rpm region is lean and it the engine is bogging, running rough, it's rich.
Of course you'll need to dyno to see how things really are with the engine. Another great tool is to install an Air/fuel mixture gauge in your exhaust system. Innovate makes several models. The A/F gauge registars real time A/F mixtures, so you can learn about what is really going on with the fuel delivery. I installed it last year and I have learned a great deal about tuning and my bikes performance.
It costs about $300 and takes 2 days or so to install, including having a sensor bung welded into the exhaust pipe. So it you like to tinker and learn, I highly recommend such a tool.
If you'd like to discuss further you can PM me and I have pics of my install.
Good luck
