R100/R80 400 watt alternator

I am thinking of buying the 400 watt alternator kit from Motorrad Elektrik.
I have read 3 good reviews from the Airheads list. Has anyone herad of any problems with them?

I've heard good things about the conversion kit too. I already have most of Rick's parts for the conversion installed on my PD. Unfortunately, there are several special purpose parts for the kit, including a special diode board, stator, and rotor.

And there's the reason I decided not to install the kit on my PD. If I'm halfway around the world and I have problems with my stock BMW charging system, I can carry a spare rotor or diode board or get one from almost any BMW dealer and get back on the road. However, if I have Rick's kit installed, I have to carry his special purpose parts or order them from him.

If I were using my BMW locally I would definitely install the kit. For my RTW bike I'll stick with the stock charging system, upgraded with the solid mounts, Thunderchild diode board, Motorrad voltage regulator, and rewound stator.

There are a few issues with the Omega upgrade. For one, I don't think Rick sells a second rotor to go with as a spare. As well, the stock rotor is not as wide and won’t generate any juice with the Omega stator. There’ve been a few failures of the 400 w upgrade. The diode board (actually made by Emerald Island in the Far East) is an absolute beauty. I changed my brushes, installed a stock rebuilt rotor from Rick and put an Omega (see pics below) diode board in (without the rest of the upgrade) and got stunning results. I nearly have to stall the bike to get the alternator light to come on. I have a good dry cell battery and an after market Transpo voltage reg as well.

My old alternator was fine but I am going to get 2 jacket liners from Gerbing, 77 watts each. I don't think the old 280 watt will handle the jackets and extra lights on the bike. I have just installed it, but I am waiting for other parts for other things on the bike before I put the bike back together. Rick says that a stock R80/100 with the headlight and taillight on will draw 150 watts. Add the rest of your elect. gears watts to get your total. He is at
Go to links on this site, his link is under Motorcycle parts.

John, I am in a similar position with the 400watt Omega and am curious what you decided to do.

kberretta: could you be more specific with the failures that you have heard about?

Go slow, be well.

I did install the Omega alternator kit. The only problem I had was installing the solid diode board mounts. Very hard to get to and of course when I moved the vent hose it broke into several pieces.
I have not heard of any problems, but if there was you can not get parts easily.
A friend of mine had a old alternator stator. I took the cover off of it and used it for the new stator.
Then I put my old rotor in my old stator with the cover and brushes in place. I packed it in a box ready to be shipped.
I had one of Rick's rewound rotors on my bike for 90,000 miles with no problems. If there should be a problem with the Omega kit my old alternator is ready to go.
