My friend's 78 Suzuki GS 1000 uses a separate rectifier and regulator. We put a new combination rectifier/regulator from a Yamaha on it and it works perfect. Pretty much they are all the same and do the exact same function. One with more cooling fins might work better as the regulator part converts extra voltage to heat. The rectifier part converts three phase ac to one phase dc.

Ok Folks I have uploads some pics and a bit of a how to for those not so mechaincally inclined.
I have given my R/R a "refresh"
There are 2 problems with the charging on these.
1. Poor grounding
2 Poor cooling.
Here is what I did.
My pics got deleted for the 1st bit but its fairly simple.......
When I took off the RR I noticed a lot of gunk behind it so it wasn't dissapating its heat properly into the frame. The ground wire is also very corroded.
First I sanded off all the paint from the frame where the RR mounts.
Then I cleaned all the crap of the back of the RR.
Then I used some 25% silver heatsink paste of the back of the RR and put it back on the frame.
I then glued a heatsink (using thermal heatsink glue) to the RR
I then attached a fan to the heatsink and wired it to the rear light circuit.
That took care of the cooling. Now the grounding.
I ****ed off the pissy little ground wire that goes from the battery to the frame. For the amount of current the bike has this is woefully inadequate. I then attached a huge low resistance ground wire (an automotive one) and attached it from the battery to the bolt on the RR. (BTW the bolthole and area around it was sanded to make a good contact)
I then attached another big ground wire from the bolthole on the RR to a sanded area on the frame for redundancy).
First you need to get yourself a fan and attach some spade terminals to it. I used a genuine Intel Fan off a Pentium 2. This a fan that justs clips on to the heatsink. They are perfect and are the same size as the R/R.
Then you need to cut some 10 amp wires about 20"(50cm) long. Tin the ends of the wires with a soldering iron, crimp on some terminals and heatshrink.
Then get yourself some splice terminals......
......and attach the positive to the brown/white wire on the plug that goes to the taillight and the negative to the green. Then tape over well.
Then route the wires back to the fan.
I then clip the new leads onto the fan and tape over to keep the water out. The fan justs clips onto the R/R. I did use a spot of glue to hold it in case of vibration etc. The completed pic also shows the huge new blue ground-wire and 2nd frame ground I used. The pic doesn't show it well but there is a very low height heatsink under the fan and one on the end of R/R as well.
Best of luck folks.

Good work trips. That means more electric juice at idle for the weak ignition which will give you a better idle. I'm going to check my r/r and ground wire later on today. I'll bet yours starts up easier too.

This might help my engine breakdown at 7,500rmp. I'm going to have a look and let you know if it helps.
I don’t have a problem starting, It always fires after one or two rotations.

I think that is my problem as well. I was riding along and suddenly it died and had no electrical power. I put in a fresh battery and it fired right up. I checked it out tonight and it isn't charging at all. So... I went to disconnect the harness from the R/R and the connector itself was fried, wires not even connected to anything anymore. Any ideas on where I can get a new connector?

If the connector was fried then that is a good indicator that the RR is cactus as well.
The connector on the CBR1000f is a custom one as the red pin is larger than the rest. Go and see as auto electrician as it is possible to replace burnt out pins.

Maybe it sucks the gas at low rpm, also, since the fuel gauge is electrical, it may now read a little different?

This is why I love this site.. My charging just went out a few weeks ago myself. Trips mentioned some "gunk" behind the regulator, and I noticed the same thing as well. The thing I'm curious about is, was that Gunk Black??? I know the smell of burned electronics, and it smelled like a blown cap!! I had black goo oozing out of my regulator and charging was NIL! When I see something of this nature, the first thing that hits my mind is electrical failure, and I have ordered another regulator!! Geeze they are expensive.. Now ya'll have me thinking that my regulator isn't bad, just needed to be grounded and cleaned properly. The ground wire was a little corroded, but not bad. When I see electrical fluid like that, and no charging my immediate thoughts go to "Faulty device"!! See its 11pm now, and I'm thinking of going out there and finding out!! Hehehehe... It's ya'll fault!

I agree with Firefox11. I can't tell ya how many times I couldn't get right to sleep and come over to the computer, read the forum(s), and the next thing ya know, i'm sitting on a cart next to something on my bike at 1:00 in the morning do something to the bike that I read about on here.

I did check out Ricks Electrics R/R's, they sure are alot cheaper than anywhere else. I'm going to see if they can FedEx me one today so that maybe I can be riding again this weekend!
I replaced the burnt pins in the connector and heat wrappped the connections, cleaned up the ground a bit and now life is good again! The idle seems smoother and I'll bet this will fix my poor gas mileage situation. That was the part that I couldn't figure out prior to the breakdown. I went on a club ride and we really rode hard and I got great gas mileage. But when I rode it easy commuting to work it was sucking down gas.
