Ok, so I currently I have no battery on my CBR 600 F2 and to start it, I jump it with a car battery. She starts right up no problems, but when I unplug the battery, the bike's gauge cluster has trouble lighting and the engine begins to bog down. I can't rev it or else it dies. It seems like the alternator isn't creating enough power for the spark. Is it supposed to do this? And I also have problems starting the bike sometimes. Out of the blue when I turn off my bike and try to restart it, my lights are off and nothing works.

Are you trying to run it without the battery installed?
If so, that's your starting point. The battery acts as a buffer to the alternator.
The bike will run, but the lights, etc. are making demands at low rpm that
the battery normally fulfills. The alternator is for charging the battery.
Get a battery if that's the case. If not, +1 to Jank's post.

Yea, I figured running without a battery is a no no. Anyways, I suspect its the RR since it gets super hot to a point where it's too HOT to the touch. I don't think that's supposed to be normal....It's a $20 part so I'm going ahead and ordering a new one to be safe. I'll keep you guys posted if a new RR was the remedy. Thanks for all your inputs!
Before you order one you maybe wanna check around to see what else works with the bike. My rectifier went out near the end of the season. I would be riding and as I came to a stop it would kill and wouldn't turn back on. So I checked into it and found that a r/r from a 03/04 suzuki gsxr would work. Pros-more modern, stays cooler, has more fins/ cons-it's a little bigger that the oem part so it will take some drilling. Pros of buying f2 r/r-no need to redrill, plug and play, could be a little cheaper. Cons-it might do the same thing it did this time and burn up, your girlfriend might get mad cuz she wants to ride! Before I soldered my wires together I just wire nutted them together and drove the bike around to make sure that the used part that I bought which came from a 03 gsxr would work. I do believe a yamaha r/r fits. There is a thread maybe it's in the sticky. I was reluctant to buy something other that the oem r/r for the f2, but I'm here to tell you mine works without any issues.
First & foremost you need to get a battery installed to properly run the ignition system. If for nothing else just to get one in there. Using a car battery isn't so bad, but don't unhook it when the bike is running. The reg/rec is getting so hot because of that reason. They get a bit warm by the nature of the work they do which creates heat in general, but you need a battery. Once a battery is installed we can test the charging system & get you squared away. Don't just start throwing parts at it.
Ok, well I installed a new battery on the bike and I fully charged it. However, the bike has problems still. Once I get the bike started and idling for about 4-5 mins, it dies out of nowhere. Starts right back up no problems. Not sure whats wrong now. I'm still waiting on the RR.
