Has anyone installed an alternator/generator that provides more power for things such as heated gear/etc. and if so , details please!!!!!!!!! 2009 400 here.

Don't know of a high output generator but I can tell you the one fitted is rated at 400 W at 5000 RPM
and my 400 still charges the battery at tick over with heated grips and vest switched on.

I don't know what technology is used in the regulators on the Burgmans but if they are typical junction type devices then I would guess the alternator/regulator system is probably 85-90% efficient. So if you could could make them perfect (e.g. 100% efficient) you're only going to see, perhaps, 450 watts or so at pretty significant expense. The raw output from the alternator is probably fairly optimal based on the available magnetic field from the rotor, which is not likely to be changed, so 450W would represent the upper limit of available power. Unless you go to an automotive style alternator with an excited armature, I don't think you will ever get much more out of the rotor/stator arrangement as built. You can squeeze a rock but you're not going to make it bleed.

The first question is why? My 2011 400 puts out sufficent from standard outlet for heated vest. 1st you have to measure or know what equipment you are adding requires, does it balance against out put and other uses of juice to run bike and its various systems.

Have you tried the Burgman with added electric equipment? or have any?

My Burgman does good job powering Aerotich vest----no dead battery at end of ride, etc. One sign of overloading system--use brake lights and engine dies---usually means charging system not keeping up with loads placed on it. Used to happen to GI's in Japan, who tried to convert their early Honda CB750's into "Honda-Davidsons" with extra front and rear light, etc. Step on brake---engine died. System not keeping up to load....bike wasn't designed for that. Years ago HD used to offer higher ouput generator "air cooled generator" for police. Today, I have heard, some funeral escorts, have second bettery mounted so when lots of slow riding with lites flashing, low RPM=low chargine rate----spare battery can be switched to.

One other point on big rubber band drive scooter---no kick start or ability to bump start----walking sucks.

I think Tom just wants to power everything, including that new 6 speaker 1000 watt stereo system he found. :lol: Maybe a trailer with a portable generator behind you would help? :lol:

My understanding is the 400/650 have pretty decent electrical output compared to many other bikes. That's still not as much as a car has probably, so you need to look at your electrical needs versus alternator output and prioritize what you use at once.

Aha, tow a small trailer with gas generator, replace Burgie humongous 400 cc engine :D with electric motor. Ta-da! Hybrid bike. Sort of.

Or not.

OMG...........Chris!!!! I was going to say the same thing about the trailer - BUT to haul all of his stereo equipment......!!!!!!! :thumbup: :thumbup:

Guys/Gals! haha!!! I have already thought of getting a harbor freight generator and also trailer and while I am at it, maybe a vette engine that the trailer will pull and then I will have enuf power to be the 1st trike with trailer than can do wheelies!!!!! The vette engine would push the 400, not pull it- of course! haha! And Chris - it isn't a thousand watt stereo. Even I am not THAT crazy!( the good lord knows that 1,000 watts wont cut it with a lunatic like me - haha!) Its actually two 700 watt amps , so 1,400 watts. Gonna have to show u peeps a pic at some point. So far, my current stock generator is doing fine but I always like to plan ahead and now, the only heated gear I use are my heated gloves but if I ever decide to do some serious cold weather riding, I may want to add the vest/jacket also and still power the stereo.

It's not a true 700 watt amp, they are more than likely talking peak power output. If it were 700watts per channel x 2 RMS the current draw would be on the order order of 116 amps @ 12vdc.

If your really concerned fit another battery and add a solar panel to the top box as it appears most of us only ride when the sun shines. Me If i want a bike to be like my car with all electrical mod cons I just choose the car as my bike is for pure enjoyment and accept its limitations because if i wanted an armchair on wheels I would have bought one. I think the latest technology batteries provide all the power one needs just changing the alternator is not an answer.

Well, in terms of seriousness. The magneto's on the burgs power output is proportional to three factors in it's design: rpm, coil windings per arm and magnet strength. So either increasing the amount of windings per coil or fitting stronger magnets (neodymium comes to mind) will increase power output over your rpm range. Or you could do both and get the best of both worlds. There are companies who do repair work that could possibly do that modification such as http://www.rmstator.com/. Not sure as to a source on new magnets though short of having some custom made. There is probably a manufacturer that would have something close enough size wise to fit.
