Electrical Woes...
I've read a bunch of threads on the Superhawks electrical problems, but thought I would post my own to see if it's any different than what I've been reading.
I'm riding a 98 Superhawk that I picked up last week, bike has 14000 miles. The only riding I've been able to do so far is commuting, and that's roughly 10 miles each way. Everynight I get home from work, I connect the battery tender, just like I did with the VFR. (I still have the VFR, and I use the same battery tender on it with zero problems). I noticed after the first night of the bike sitting on the tender, it was still in charge status. It shouldn't still be in charge status afer 12 hours. The battery is brand new, and after testing it at work, I found out the battery is good.
Today I go out for a ride and after 40 miles I come to a stoplight and notice the tripmeter is blinking; sometimes fast, sometimes slow. Then my tach drops to zero. I pull off the road and check fuses, they're fine. I put my hand on the R/R, it is room temperature. Put my gear back on, now the bike won't start! After jump starting the bike from a car (it was not running), I start to head back home. Bike seems to be normal again, then the tach, speedo, and and the whole instrument cluster go out on me. No lights, nothing. Go about 5 miles and I had to slow down for a stop sign w/3 cars ahead of me. Bike dies out again, but I was just slowing down. Got her jumped again, and made a bee line for the nearest interstate. As I'm exiting the interstate to go to my house the pipes start popping and the bike died again at the entrance to my neighborhood.
So....
Get home, remove the plastics. After looking it over, I see no sign of fried connectors, and all the fuses are fine. The only thing I noticed was that the R/R (original BTW) seems to have a small hole in it. I tap it on my hand and a bunch of black "dust" comes out.
It's my understanding that the R/R is to keep the battery voltage from going to high, and the stator is to keep it at a minimum. Being that the battery was drained, I would think that the stator would be the problem. I have no way of testing this stuff, but I will be going to a reputable tech this week.
Any thoughts from anyone who has gone through this?

The stator is what generates the power, the R/R regulates it, sending the right amount to the battery when called for. It could be either one of those that is causing the issue. From you description I would have to say R/R though.
Why are you sticking it on a battery tender every night? I've never owned one or used one, and have had no problems at all. I had to replace the battery in the hawk after leaving it sit for over a year, but that was the only problem ever.

Download the shop manual (check threads) or buy one on fleabay. Checking the alternator (stator & armature) is easy, as is the VR/R with a good digi multimeter. If what you said is true about the hole and dust, then your VR/R is probably toast internally. Either get a new Honda or AM unit, or adapt one from another make (again, plenty of threads). I'm currently behind in my research to develop "crimp-on roadside adapter kit. Check the connector again for signs of burning, and be thankful more damage was not done.

It will tell you how to test the R/R.... your symptoms sound like classic R/R issues.

it absolutely sounds like the r/r. i just had mine die on me a little while ago. in the manual for our bike, it gives you tests to do and it tells you whats wrong if certain tests come up with certain results. they're all easy tests you cant do with a multimeter. i very strongly suggest buying a yamaha r1 r/r and putting that on your bike. its a very easy swap, even if you dont buy a new rear wiring loom to get the yamaha plug. all you have to do is cut off the old honda plug (keeping as much length on the wire as you can, even though there's plenty there), and strip the wires enough to fit some quick disconnects on there. make sure you crimp the quick disconnects good, there is no need to solder them. wrap electrical tape around the quick disconnect from the wires all the way to the very end of the connector. if there is any exposed metal on the connectors it could cause an arc. plug the three yellow wires into the three connectors on top (it doesnt matter the order of them), the green wire on the bottom left, and red wire on the bottom right. after this, wrap the whole thing in electrical tape like a madman and your good to go. just make sure you get pliers and make sure the connectors are in there good and tight. you'll only be able to mount it with the top screw also, seeing as how the yamaha r/r is much bigger, but it still mounts just fine. just use the bigger of the two screws that came out of the old r/r. good luck.

Definately an R/R problem. Same thing happened to a mate. All started with a low battery that he had to jump start all the time. As you ride along the power slowly drains and the popping through the pipes is your fuel pump shutting down and the motor starving for fuel. The rectifier is overcharging the battery. The battery may even be swollen and bulging out. If you keep riding the bike like this you will cook all your electicals. Very expensive. New R/R; new battery; problem solved. Good luck.

*whispers* "I see dead batteries"

Looks like I'll have to dust the cobwebs off the cage and take that to work this week.

I was able to get hold of a spare R/R today. Hooked it up, had my tech friend run the diagnostics, and the bike is golden! Now to get the R1 r/r and wire it in.
Thanks guys for all the help!
