So I went to start my bike, it has not been running all winter, i fired it up once or twice to show off to some ladies.
But seriously, the volt meter reads 10.0 and 9.0, the bike will not start! The only way I got it to turn over was to run it down a gently hill and pop the clutch. Once started the battery does run UP to 11, then 12, then 13.7.
Once started, It will then bounce from 13.7 - 13.8v - 13.7 again. I had left this bike to run for about 10mins and it seems to be able to start up again... but what should/ can be done here?
How can I charge this battery?
I have a Honda 1000 generator can I use that?
Do i have to boost it with another bike?
I know that I cannot hook it up to my car battery because they are different voltages! What do I do fellas

Re: Battery Trouble! Ducati 749 dark
You need to get a battery tender, and when you put your new battery in it has connections that will stay on your battery and you just plug it in after you are done riding and cleaning her. oh one more thing when you get a new battery you need to charge it for 8 to 12 hours before using it, they are not like a car battery buy it, put it in, and go, you have to charge them up first. The tender should keep you battery charge all winter long. I hope this helps you. One more thing, 749's do not like weak batteries as you have found out. Buy a new one, install a tender and and use it, the battery will last much longer.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

If you battery had a standard reading of 11.5 volts that drops down to .5 volts when you put load on the battery, your battery has gone bad. A healthy battery will give you a static reading of around 12.6 volts, and that will drop to about 12 volts when you're starting the bike. Conversely, when the bike is running, you should see 13.5-14.5 volts across the battery terminals. That shows that the alternator is charging and that the battery is good.
I have a vehicle with a battery going south. I have a static voltage of 12.16 volts, and I only get about 13.2 volts across the terminal when the car is running and the alternator is charging the battery. Soon, it will be time to change out the battery.
If the bike sat without being used over the winter It could be bad gas. if gas sits without being used for an extended period of time it destabilizes and gums up carborators and fuel injectors, you need to add a fuel stabilizer to gas when storing for winter. To fix the problem the gas has to be drained from tank, then refil with fresh gas and appropriate amount of carborator/fuel injector cleaner/treatment. Then start the bike and let it run it should clean itself out and start running smooth. If bike did not sit unused for winter its possible they installed the wrong plugs sometimes they talk you into spending more money on platinum or split fire/gimmick plugs (always use the exact same plug that came in the bike when it was new!!!!!)
Seriously, what symptoms are you having? I assume the bike isn't starting. Does it crank? If so, does it fire at all? Starts then stalls? Smokes? Makes weird noises?
When I worked as a motorcycle mechanic, this was my busiest time of year when countless bikes would arrive in the backs of pickup trucks. Most of the time the problem is that they sat all winter with fuel in the carbs. Fuel in the tank isn't generally a problem. But before putting the bike up after the last ride of the year, if people would just shut off the fuel while the bike is still running, then wait until the engine dies before shutting off the ignition, at least 90% of the bikes that fail to start in the spring wouldn't have any trouble at all.
There are more steps that should be taken for putting a bike up for the season, but this one simple step is the most important and would prevent a lot of non-running bikes swamping the mechanics, who have to take apart carbs with extremely tiny jets and get everything cleaned up.
?.....was the bang when you tried to start the bike...or as you turned ignition on?...if when you turned ignition on sounds like you need to check wireing...if bang was when you truned eneing over it could be unburt petrol that banged when bike tried to fire up !!...
try new spark plugs. and for next winter you're better off not draining everything. best thing is add some fuel stabilizer and run it a few minutes once in a while. empty lines tanks and carbs attract moisture.
If you used the choke to start the bike last winter, you probably fouled the plugs. Depending on the age of the plugs, you can either clean and re-gap them or replace them with new, which also have to be checked for gap.
Secondly, if you did not run the bike out of fuel after starting it, chances are you have some build up in the carb jets. New, clean fuel and Techron or Seafoam gas treatment will help if it's not too bad. Follow directions on the can. I personally used Seafoam but Techron is recommended by Honda. Be sure to mix per instructions, which on Seafoam is 1 oz. per gal.
during the winter you can get build up on the tip of your spark plug that will prevent the engine from firing. remove the spark plug and soak it in gas for ten minutes or so. Dry it ogg with a clean towel reinstall it and it should start right up.
