    The actual battery cant be the issue, this is the 3rd battery on this bike that has had the same problem as its predecessors. As for the alternator, it will charge the battery every time its ridden, so as long as i ride it every day Im OK, put if the bike sites for a couple days of no use its all over.

Even though the battery is new does not mean its not faulty!
Also you might want to check the bikes alternater and make sure it is charging the battery when you are running the bike!
I hope this helps you!

I have the same bike and it has a design flaw. If you leave the key turned on it will drain the battery very quickly. If you just turn the key off every time you get off the bike it won't drain it.

Hi, i went for a ride 3 days ago and parked the bike in the garage since, this morning my k8 gsxr 1000 didn't' want to start, when pushing the starter button I hear a 'click&am

Most of the time this will be the battery, the battery is very weak, will need to be recharged using a trickle charger, if the battery won't hold charge, you need to replace the battery.

It might also be a faulty starter motor and or solenoid.

You will most likely have some sort of electrical problem, a drain problem, parasitic draw.

The problem has to be found and fixed.

Hope this helped and have a nice day.

1995 Buell S2 Battery will not start the bike

Sounds like the battery is not holding a charge, if you connect a volt meter just after charging you will get a good reading, each cell of a battery is 2.2 volts so you should have a reading of 13 volts. Battery may have a faulty cell, which will drag the other cells down, is the electolite covering the plates in all the cells, this will affect the battery's ability to hold a charge. My Suzuki did this earlier on this year, nearly bought a new battery, checked and topped up the electolite first and its been fine since

Black smoke coming from exhaust occasionally.

Black smoke is indicative of carbon or incomplete combustion caused by either poor ignition (weak spark) or too much fuel (choke setting). Check out these areas.

Hi i have an 08 xv1900a midnight star & if i leave it parked in my garage for a couple of weeks when in go to start it there is not enough power in the battery to turn the engine over. any idea's?...

If there was some point at which you drained the battery too much (left the ignition or parking light on) and then recharged the batttery, the battery will no longer hold a full 12 volt charge, nor will it ever be able to hold a charge for more than a week thereafter. You need a new battery.
The other solution is a little obvious though -- why leave such a beautiful bike hiding in the garage for that long anyway?

sounds like the battery doesn't have enough power.
Battery may be bad, or your charging system is bad.
If the bike was sitting for a while not being ridden (longer than 3 weeks) then the battery is probably dead.
go to a local powersports shop and ask them about a "trickle charger" this is what you plug the bike into when you park the bike for a long time like the winter. You can dfind a cheap charger for about $20. It has to be a trickle charger not a regular battery charger otherwise it could overcharge and the battery could explode or even catch fire. This will keep your battery from dieing everytime you park the bike for an extended period of time.

The 12 volt battery(LUCAS 065/3) on my FORD FIESTA 1100cc is 4 years old, in that time i have only driven 1,600 miles as my journeys are usually very local. I make sure i use the car twice a week to keep...

Running so few miles has accelerated the aging of the battery - the battery never had a chance to fully recharge in such small trips -  so now you have to replace it a year sooner than usual.
Just replace it.

Kazuma battery will not hold a charge

This is a common problem with chinese atvs. I installed a toggle switch on the positive wire from the battery. When my daughter is finished riding, I simply flip the switch and all power to the bike is killed, preserving the battery.

Kiil my battery

with the lights on for well over a week. (in my locked garage incase your wondering why I still have a bike) Needless to say the battery is dead. It's been on a trickle charger since Sunday afternoon (now Tuesday afternoon) and it still indicates charging. We did try it in the bike anyways and no go. Do you think I killed it? The dealership told me it might take a good 2-3 days to charge it back up if I didn't kill it. The battery is 3 months old.... should I just go out a buy a new battery at this point? Ahhh....lessons learned the hard way. Slap a trickle charger with a float on it and see what happens. No way to find out how bad it is until you try to fix it. And draining then charging a battery is one of the worst things you can do to it. Personally, I couldn't stand not riding for 3 days, so I'd buy a new battery anyways. But that's just me.,,,
