So I have a good level of understanding of electronics, my current system is a 18 volt drill battery and sacrificed drill, a 12v regulator, motorcycle led turn signal relay, ,all wrapped up in a harbor freight ammo can. I use led strip lights, works nicely.

Anyway, there are these gy6 motor things, for go karts or whatever, they have a stator in them to generate power, that gets directed towards the regulator/rectifier and distributed to the battery and other electrical system bells and whistles. Here's the eBay item number for this part 291155838768.

Now I don't know too much about this, but I know it can generate enough juice to charge a 12v sealed lead acid battery whilst powering some kinda headlamp and not starving it's cdi of the needed power to actually keep the machine running.

Looks like the inside of it has a keyed shaft, I don't know if it's the same 5/8th found in a shift kit, but if it is I do think I have room in my setup to simply slip it in and let it spin while the motor's engaged to the wheels.

Does anyone have knowledge about how these stators work? Anyone think it wouldn't work in theory? My current system works rather nicely, but this would be nice since I don't have to remove a battery and charge it, and no more batteries dying out on the road leaving me without my turn signals.

Any input is highly desired, thanks.
 
Advantages over my old system: don't need to take a battery out to charge, making it even more standalone (currently that's watts the only thing needed to power the the system, 2 batteries, swap a charged one for an empty one.)
Wouldn't it be nice to charge forever without having to forget about the battery being almost dead, then die leaving you at an intersection where 5 roads meet with no signals, or reliable headlight in the middle of the dark with cars at each road making turns and almost hitting you.

Yeah that sucks. It's annoying in general not being able to use a turn signal and a headlamp that can be blinked. You have to take hands off the bars to signal your intentions.

The other advantage: if it fails to power a battery, like the stator burns out, it can be bypassed electrically. I have a small 12 volt li-ion battery. It's got some kinda amperage I don't believe is real, but it seems to do a good job at powering certain 12 volt devices with remarkable longevity. If the amperage is a truth, then it's effectively the same as my ni-cad setup. Only thing I noticed is the li ion battery didn't work reliably in the winter being super cold.

Anyway, the system could be bypassed, with that plug in li ion battery, and use that battery conservatively untill a fix can be made, and it would power my lights generally as long.

Very useful at night if going slow on faster trafficked road, also can make 4 way signals, if I use a double pole double throw switch, like I do for my kill/light power switch, I can use the "hazard" light indicatedor in my speedometer to let me know of my hazards are on. You can tell for certain at night vs day, so an indicator would be useful.

Anyways, just my thoughts, if you'd like a list of what I did to make a turn signal and light system, just ask, maybe I'd post pictures sometime if really wanted.
 
I'll side with not doing it, it needs to rotate at engine rpm speeds to work nicely, the jackshaft doesn't spin fast enough to do the job proper, no real way to hook up directly to the crankshaft arms, and running against the wheel with a friction drive isn't a good setup either...

I spent $30.00+ shipping (35.00 total)
After installing the mini gen I noticed a loss in power (HP). I don't have anything connected up to it yet. I built a reg/rectifier to charge Li-ion (8.4v) battery pack.
Wondering when everything is hooked up, will I loose any more HP while charging the batteries.
Doesn't have enough HP for my taste as it is.
After all lights are in place (turn signals, brake, tail, head lamp + a horn). It will be time for engine performance mods.
 
it is an independent system that in no way can affect your engines power output.
