I think you need to determine if you have a parasitic drain on your bike. I hate to say this, but you're going to need to access your battery. This will probably mean you will have to remove the RH side lower fairing (or at least loosen it and move it away from the frame) and then remove ALL of the bolts holding the battery cover on (don't try to cheat and leave the RH lower fairing in place and then not be able to see the one hidden bolt). Charge the battery fully and then disconnect the negative terminal from the battery. Leave the battery for however long it normally takes to go dead, and then reconnect the battery. If the battery is dead and will not start the bike, then you will need a battery. If the battery is ok and will start the bike, then you have a parasitic draw and this will need to be diagnosed.....the fun begins at that time (LOL). This is not the way I would normally diagnose this type of concern, but without the proper tools and education/experience, this is a quick and dirty method.

Jezuz..... put a battery tender lead on it and be done with it.
If everytime you go for a ride and your battery is dead.... sell the bike....you're not riding it enough....lol

what year is your bike? Put an Interstate Battery in there! and then use the tender. never have to worry about it for a long time!

paul no after i stop it will not start again but it does not alway happen so i do not know where to go
my bike is a 2002 zx12r i will pull the battery and give it a good charge
tools and know how no problem what do i need to do to find the draw?

There is a simple tool you can make for use with a DVOM to measure parasitic drains. Here is what you need for materials: 3' each of red and black 10 gauge wire, a 1 ohm resistor (the biggest you can find...1/2 watt, 1 watt, etc), ends to go into the DVOM (are they called banana clips?), and a set of one red and one black medium sized spring loaded alligator type clips (same as the ones used on trickle chargers) and some black tape. I got all of this stuff at Radio Shack at one point in time. Here is how to assembly these parts: solder the alligator clips and the banana clips onto their respective wire ends. Bare a section of wire close to the banana clip ends of each wire and install the 1 ohm resistor bridging across the two wires. When I built this I staggered the bare areas to allow the resistor to be installed parallel to the wires, and then soldered the connections and taped the whole setup together to make a "harness".
The operation of this tool is simple: install the banana clip ends into the red and black Volt/ohm connections on your DVOM. Do not install them in the Amnmeter connections. Disconnect the battery and connect the red alligator clip onto the negative cable and the black clip to the battery. Think in terms of relative "positive and negative"...the cable is more positive than the battery post...therefore the red goes to it, etc. Turn on your DVOM to the VOLTMETER mode and whatever is read in volts is your draw in amps (or milliamps). As an example a 1.5 volt reading on the meter indicates you have a 1.5 amp draw. Remember OHM's law: E=IR.... therefore if r=1 ohm, then E=I x 1 or E=I. "I" is actually ampreage and "E" is voltage. This means Voltage read on the meter equals ampreage.
On a fuel injected bike I would assume that there is some power useage by the ECU (for the Keep alive memory or KAM), but I would think that it should not draw more than .010 amps or so (this is just a guess.... DO NOT quote me on that number). Anything beyond .025 A is way too much and is killing your battery. If it is too high, start pulling fuses, and disconnect the voltage regulator (there are diodes inside that can fail and allow current to flow). Beyond that, you have to be a good sleuth the figure it out.

Check your stator plug in the rear, under the seat. I had some problems with my bike not wanting to restart if I sat in traffic to long. There was oil in my plug, and one of the connectores burnt up.

Where is that at under the seat? My bike just started doing that too! It had been sitting since December due to no headlights and house reconstruction/no driveway. Now I have the headlights fixed. After riding it...it seems to be drained. I charged it up the other day and haven't ridden it...but it started right up. [shrugs]

Check the battery first. Charge it, hopefully with a trickle charge, 1.5 A for about 5-10 hours. Take it off the charger and wait 30-60 minutes and put a meter on it. If it's over 12.6 V then it's ok, 12-12.6 charge it a little more and test again, if it's under 12 it's trash.
I'd test the alternator output next since it's easy to do. If you need instructions I'll post them.
The plug is easy to get to. Remove both seats, and look on the left (kickstand) side and you'll see two round black plugs resting in grey foam rubber near the front of the tail section plastic. The plug you want is closest to the front and has 3 wires, two yellows. Don't be surprised if you pull it apart and find oil in it.
I'm chasing the same issue and seem to have it figured out. Good luck.

Thanks Dave! You da man!
I JUST got done taking my bike for a spin. No problems so far. I took the battery out and let it charge overnight. Plugged it in the next day and it was over 12...so my friends said.

hey hawkman i had the same problem with the head lites what was the fix?
i did the j box . it work for a week now i by passed the relay in the box and set it up as a euro bike
canadamaxxer thank for the in pput i will do this over the weekend. i got a new battery on stand by but i have been riding all week with no proble but slow to start so I will look in to every thing this saturday i will let you know what i find tc

My battery is 3 years old and I keep a Tender on it most of the time. I keep thinking it is going to crap out on me this year. How long have you guys had your stock battery? Mine is a 2000A1.

more trouble it just happened again on Saturday before i was to leave on a big group ride to the mountins here in germay so i am back to looking for the problem?

I had the same problem as Fathouse....you better check that plug in the back. Your battery is not recharging from the stator.
