Run a bike without battery?

Hey are you are to start a scooter on its kick start if there is NO battery installed. Do you have to modify anything or connect the terminals! With doing so cause any damage!

you sure can,but cleary nothing will charge or run.

You sure can!

Start that bad boy up, jump in the saddle and hold on.

I would say no as a battery would be needed to provide power for the spark.

Not if it runs a little magneto or whatever. We have a bike that hasn't had a battery for 30 years, that's a hell of a run on lol

it maybe operating with a flat battery started via kikstart , You do need a battery on the therminals or you could damage the charge circuit some bikes like old 250cc honda from 1960 will not run without battery and the battery will need to be fully charged. same as my dads 1989 600cc cbr wont run right without a good battery , most scooters howeverdo run with a flat battery as they also make them with no batterys on same models

Depends. Generally no on anything vaguely modern because the regulator will have to shunt all generated electrical power to earth, which will cook it.

Only old motors with points/magneto ignition will run without a battery and the battery wires must not be connected as Tony said. Anything modern with electronic CDI ignition needs a good battery to run.

i have a bike with electronic ignition, have removed the battery and starter motor. kicks and runs absolutely fine.

CDI ignition doesn't necessarily need a battery. See old Honda dirtbikes XR etc.

same way a petrol lawn mower start, give the start cord a good hard wank, i meant yank, my bad.

ditto that, mine with CDI igntion runs fine with no battery, indicators dont at idle though

Are you drunk or on drugs!

ralphdog1, Apr 25, 2:24pm
With the info you have given ("A Scooter") the definite answer is yes and no

flybye_in_a_rx7, Apr 25, 2:36pm
worked for me on a fxr150. lights were just dim when idling was the only difference. i cant remember if i ran it with a dead battery or no battery though.

As other posters have said, it can be done, but IMHO it is very unkind on the electrical system to do so.
