Running without a battery (cafe project)

[masterofpuppets]

Hi people,

I am in the process of building a GB600R (with a xr600r motor in a GB400 frame). i have everything in place, the motor runs, and now i have the daunting task of sorting out all the electrics. i have a couple of questions:
i am planning on using a loom from an XR or XL that had street legal lighting - i tried mating the xr stator to the gb loom but no go.
i do not want to have a battery - its kick only - will my lights be able to run off just the stator?
the stator that came with the XR motor only had coils around half its circumference - i.e. it was pretty small. i assume it is off a dirt only bike with no lights, and will need to get a bigger one.

any wisdom?

i tried putting the GB stator in the XR motor, which would be the easiest option, but it is too deep and didnt clear the flywheel. even then, would it be possible to run the bike without a battery?

Thanks,
Nick

I think the XR stator will have one set of windings that is bigger than the rest for the ignition.

Why not rewind the XR stator (if the GB one doesn't fit) so it can supply enough power to run headlights + the ignition? It may already make enough to do it.
Just run it through a regulator and go from there.

the early XR 's were 6 volt ...

You can mate the two , Honestly I would build my own wiring loom it isnt hard, infact there is software to run electrical circuits on a computer ( quite fun , the windows version ,the light actually light up !!)

anyway for a road bike I would run a small battery 12v as , it may sometimes be a pain to start , as the strength of the spark relies on the speed of the rotor in a simplistic way

and a small 12v reg/rect hidden in front of the engine or under the seat would be fine

or if space is an issue two smaller batteries in different spots, wired together

Or if you do decide on a battery and want small, very light and powerful, you could try a Shorai...

ok... have a look at this wiring diagram. it seems to have averything required in terms of lighting, and no battery/charging system.

i would like to go down this path, as this is the alternator that i now have in the motor (with 3 wires coming from it - some xrs had 4 or 5).

the only issue i could think of would be the legality of a 25w headlight - will that be too dim?

thanks

looks ok . its just a the same circuit minus a battery ,

if you want to run with out a battery fit a large power capacator in place of the battery, they can be placed any where there is a space just keep them away from to much heat (they will explode if subject to too much heat) Don't run with out either a battery or a capacator or you will be replacing the reg rec all the time.

ok... thanks for the replies above.

i have found myself a loom, same as the one in the diagram above. I am a bit concerned with the output of the stator and being able to handle a bigger headlight.

if i were to go LED for tail/brake and indicators, could i just up the headlight to a 55w with no other mods?

Should i be expecting issues with ligths being dim at low revs due to the lack of a battery?
