I turned the ignition key and all of the lights went on as expected then when I tried to start the bike everything went dead. I don't know if it's the battery or an electrical problem. The battery is over a year old and the bike has been running fine up to a few days ago. Any suggestions?

Re: motorcycle wont start
Check the battery connections, especially if you hear a click just before it goes dead. I know that on my bike, when this happens, the screws that hold the battery cables in place have backed out and not getting a good contact. You would think that with a bad contact that it would stay dead when you turn the key off then back on, but oddly, everything comes back on normally until I hit the starter button. Check the cables.

Pull the spark plugs out and hit the starter. This will make sure that the engine is not locked up. If the starter does not turn the engine, put the bike in first gear and have someone push you, making sure the engine is free. If the engine is OK, your starter is probably jammed and needs replaced. That wire getting hot is a dead giveaway something is locked up tight...starter or engine. If ya have a large hi-performance engine in the bike, chances are your stock starter won't do the job.
Start by checking the battery. Turning on yer bike and letting it idle is gonna drain the battery over time. Check the charge with a voltmeter. Should be at 12.5 Amps at least. If it is, I'd check the battery cables next for good tight clean connections ( if u dont have one - get a charger) If that dont do it - get back with me - I got more
What u are describing is typical of a faulty ignition system, but could also be a fuel problem. I check by removing the aircleaner and rotating the throttle. If u see a nice spray of fuel, thats probably not the problem. Check for a spark at the plugs. I can explain how if you need me to. If you cant see a good spark, U have an electrical problem. I had a crank position sensor go bad on me. Dont do what I did (replaced the battery, ignition, and regulator as part of my diagnosis procedure)
Another common problem. Open transmitter, remove battery - there's a small tang dead center under battery. I think it's bent down. Use small screwdriver bend upward to act as spring against battery. Reinstall battery and cover. That should do it! Works for 80% of transmitters. Otherwise you have to take it to a dealer and they'll put it on the digital tech and relearn your code to your moduel, but battery trick works most of the time. It gets bent down being in pockets and getting the button pushed. Let me know if this worked.
You didnt mention how you tried to jump it. If it was from a car battery, you could have fried a sensor. If the car you jumped it from was fired up while conneted to your bike, thats the problem right there
If the battery has a charge and the connections are all good, you have to have some juice goin through your system and should at the very least get a headlight, IF the bike knows its on. I'd check the starter switch on the handle bar.....did u kill it
accidently...its happened before.....maybe a leads popped off the key switch.
if that all fails
Sometimes battery connections look good, but arent. Try torquing them a little tighter.....good luck
Need more info on the model and year of the bike whether it has a generator/mechanical or solid state regulator or has a stator/solid state regulator. and did you just fire it up let it run and shut it off the other day or did you ride it for a while and then shut it off? Could be a charging problem or a starter/solenoid problem.
