Bike left me stranded this weekend

Took my 01 750 out for first real ride this weekend. 60 miles each way, have done it multiple time on my Rebel 250 so I was looking forward to the difference in power. On the way thereeverything seemed good until I hit traffic. When I came to a stop the bike stalled. Started right back up, shoulda took it back home but what the heck Im half way there already. Get to my friends house, but when I got to stoplights I found bike idling around 3000 rpms and adjusted to bring it down. Was there for a couple hours. Started bike to leave, ran for about 5 min then slowly sputtered and stalled. Started back up and adjusted idle again this time to raise it. First time I went to leave I stood bike up and rpms went up, sat it back on side stand and rpms went back down. Played with idle screw again. Go to leave rpms stayed when I stood bike up. Get about half a mile for friends house and I notice something is off. I cant describe it, was going about 55 but something just felt wierd. I decided to pull over, as I did when I got to about 5 mph bike stalled out again. Tried to start but could not keep it running more than a couple seconds, eventually the battery went dead. Im hoping to use this as an excuse to get a maintainence free gel battery. Do you think that is my problem or where else should I look? BTW the bike hadnt been ridden or started in a week and I forgot to hook charger up before I went out of town.

I would look at the throtle cabe first, by moving the bike and the throttle moved you might have a cabel sticking.

I agree with Chad. That'd be a good starting place.

And a low battery could also contibute. Give it a good charge as well and let us know what ya find out.

simmilar happened with me when my stator died.... yours just may have a small short, which is reducing its output... i would love to say its something else, but a quick check once its running with an AC volt meter on the stator plug (check the yellow wires, disconnected from the r/r) to insure you are getting voltage.... idle should be 10-12 vac, and 5k rpms should show >70-80 vac. i do hope i am wrong for your sake, but the traffic is my warning

got her charged today. started and let her warm up. then shut off for about 10 min. started her back up and after 5 mins of running I had antifreeze all over my garage floor. checked and found the fan not spinning just a hum. moved it with a screw driver and started spinning again. dont know if this is cause of stranding the other night but I know this isnt good. guess ill be looking new fan motor. how hard is it to replace these? is it just the motor or does the whole radiator assembly have to be done? other than that she ran fine. I do still get a backfire at idle but ive never played with the air mix screw so it might be ok with adjustment.

Where did the antofreeze come from, did the fan cut the radiator?
It may have if the berring on the motor came loose. Yes you can chenge the fan only.

antifreeze was coming from drain tube at bottom of bike. I figured it dumps antifreeze to relieve pressure.

You can usually find a fan on eBay for next to nothing, but I think I'd suspect the relay or the thermostat. Folks here can walk you through testing those if you need to.

However, I have to agree with Hizzo, that the fact that the battery didn't seem to be holding the charge might have to do with your stator and/or your voltage regulator - the stalling in traffic, difficult restarting, restarting only after sitting awhile...sounds highly suspicious in that regard (and, sadly, familiar).

If you check your battery with a voltmeter, and if I'm remembering correctly, I think it should measure 14 v after a full charge, and somewhere around 12.5 when the bike's running. If your charging system is working okay, then if you run the bike, stop it, and restart, you should still get about a 14 volt reading. If it's well under this, then the battery isn't getting recharged properly. We can also walk you through testing the leads on your stator and regulator if you need to.

might not be the fan motor after all. was feeling around and the blade feels like it came loose causeing it to sit against the radiator. will pull apart next chance i get. curious question for ya. at the choke is it off when it is all the way down of when it is up near the hazard button? bike tends to die when it is not as close to all the way down.

Choke is on towards the rider, off when pushed away.
