well i went to go to the track today and bike started fine then turned off so i choked it started it agean and drove it to my truck and it turned off agean so i checked my gas. it was a little low so i switched it to the res. and started it agean with no problem but it turned right back off and after that i tryed to start it back and it sounded like the battery was dieing then nothing but clicking and some times a buzzing sound. tryed jumping it but nothing still. i dont have a battery tester but i do have a volt meter and it shows it having 11 and 12 volts. i dont think its this but about 4 days ago i put a pro design kill switch on and i put it on like some other forums said do by splicing to the red and white wires and it worked fine and ive tested it about 6 or so times to see if it worked and drove it around the field by my house for about 2 hrs. with no problems till now. so i tryed taking the kill switch off to see if that was what was wrong and its still doing the samething. so now im asking you guys. :what

Make sure all your connections from the battery to the starter, and the ground where it attaches to where the clutch cable bracket mounts is good, check the smaller gauge ground wire coming off you negative terminal is still good and connected at the bullet style connector. You also need to see what volts the battery is showing when you try to start it. And last but not least when you tried jump starting it did you connect it to the terminals on the battery?

I know the cables are good going to the battery, ill have to check the others...and when you hit the start button it shows 6 and 7 volts..and yes when I jumped it I hooked it to the battery

crank bearing sounds like to me, mine did the same shit, I could pull start it, but the battery didnt have the ass, eventually the crank seized and it was rebuild time. sorry buddy but thats my guess
