Gsxr250 died on ride

[lone_slayer]

Well Got my Gsxr250 on the road for its first real ride, rode around for about an hour then she went up and died lost all power and it started slowing down. I Pulled over and couldnt restart it realised the battery was pretty much dead so turned off the headlight and gave it a push start and she went, A few minnutes later turned on the headlight and she died again. Another push start with no headlight and I got home turned the headlight on and off she went. Any Ideas whats wrong?
Is it just the Battery or somthing else?

blown reg/rect if my guess, easy to check if you got a voltmeter (battery running voltage should be higher than when it's not running) make sure to put that battery on a charger so it doesn't get fucked too.

basically what the last guy said. as a basic test, use a volt meter when bike is sitting (turned off) and battery should read around 12.4-12.8 volts.

if that looks ok, you should turn the bike on, and rev it up to about 7000rpm. it should then read about 14.4 volts or so.

if its under 14.4volts when being revved at 7k rpm, reg/rec is broken.

that a starting point. could also be a shagged battery.

Make sure your battery is fully charged before worring too much about measuring the battery volts.

Sounds like the battery is flat, that could be a stuffed regulator/rectifier not recharging it, or it could just be a flat baterry from having sat too long or killed by a buggered reg/rect.

First things first though, get that battery charged and then look at things.

Get your hands on a multimeter and follow this flow chart.

Should these bikes be able to run without the battery? ie start bike disconnect battery?

[Jonno.]

Shouldn't do.

Went for another ride yesterday same thing happened so its definatly not a 1 off **Bugger** I suppose I should ask at this age of bike do I need to leave the headlight on all the time?

new law requires headlight to be on at all times

once you have figured out that it is the regulator rectifier, have a hunt around for a second hand one or aftermarket replacement

riding around can do more damage to the bike if it is the reg/rect

popped in and saw a motorbike mechanic the other day and he put a voltmeter across the battery while it was running and got about 11.5v (lights were on) he said if it was the reg/rec it would probably be reading high so he said it was likly to be the stator?(i think) and that he can get it rewound for about $220. Does this diagnosis sound right and what do you think of the price? have also been offered a 2nd hand one delivered to taupo for about $125 ($80 + $45 delivery from the cold south)

The mechanic has given you a sensible guess. But you can have RR faults that create a low voltage. Stator output is easy to measure, check it before spending $$ on a rewind.
