I bed help trying to get my motorcycle running

Never lay motorcycles on their side to transport them! You have oil in the engine, gas in the tank and carburetor and sulfuric acid in the battery. They all rely on the bike being upright.

If the battery had to be jump started, it means it was flat. There can only be two reasons for this, the bike has been stored for a length of time (2 months to a year) and the battery has gone flat, or the battery is old and faulty. Lead acid batteries need to be kept fully charged at all times to stop the plates inside degrading and buckling.

First thing you do is put the battery onto a battery charger for 8 hours. Then try starting the bike. If it turns over strongly, then the battery may be saved. If it is weak turning over, you need a new battery.

Once you have a good battery, the rest should be easy.

Haven't run the bike in a while, won't start. I have run the battery down trying. Where do I hook up to "jump start" from a (non running I am told) car?

Personally, unless I was stranded somewhere, I wouldn't jump start the bike. I'd rather recharge the battery and try to start the engine again. But, you may wish to find out why the engine is not starting rather than continue to run down the battery or take a chance of damaging electronic components with a voltage spike. You didn't tell me what year and model the bike was nor whether it's carbureted or fuel injected. If's it's been sitting for an extended period of time, the fuel system may be gummed up due to the fuel evaporating and leaving the gummy residue to stop up the fuel passageways. But, if you still want to jump start the engine, connect the jumper cable directly to the battery in the bike, positive side first to positive post of the battery. Connect the negative from the car's frame or engine to the bikes engine or frame last. This prevents a spark and the possibility of the battery blowing up your face. I've had it happen before and it ain't fun.

Good Luck

Hello, I have a 2002 Yzf426 which refuses to start(Bought as a non runner) the previous owner told me the bike was running he stopped for 30 mins and it would not start. As a precaution i have checked and...

I am speaking from my Yamaha XS1100, with 4 carburetors.It is a 1980 model, but the carburetors are always gunking up, especially if it sits over winter with gasoline in the tank. This also happens more frequently with the alcohol laced fuel that you have to buy now days. The alcohol causes it to absorb water that mixes with the gasoline and alcohol to form a sticky gunk that blocks up the orifices in the carburetors. The first thing that you can try is to get some Seafoam additive, or maybe Textron. Pour out all of the gasoline in your tank and change the inline filters if possible. Fill the tank with fresh gasoline and add the Seafoam in a generous amount. Allow the bike to sit over night and try to start it. You may get lucky and get the bike to fire up. If it runs rough and doesn't smooth out, you may have to clean your carburetor. See:

Just bought a bike and the battery was bad .so i tried to jump it off with a car and it stop trying to turn over at all. went and got a new one and it's still not turning over.

It may have blown a fuse,

Be carefull jumping of a car battery, as when it starts and you give it a rev the car battery will accept more current than the bike can produce and can damage the charge circuit.

Install new plugs, the stock plugs are NGK R CR9E. Clean the air filter. Drain the carb float bowls. Now make sure the gas valve is turned on. Charge the battery with a low amp charger, 3 to 5 amp, overnight. Be sure water covers the top of the plates in the battery before charging. Give the air cleaner intake a shot of starting spray when all is ready. Also, don't believe anything the previous owner said.

Have 1983 Yamaha Virago 550. Won't maintain charge??

Hi and welcome to FixYa,

Offhand, even if the the stator / charging coil is defective or for that matter even the regulator, the bike should start and run on a fully charged battery. The only problem would be that the bike would die eventually. If haven't been tried, have the battery load tested not just voltmeter test.

Please postback after the load test. Hopefully by then, I would have the wiring diagram.

Good luck and thank you for asking FixYa.

Burgman 250 will not start

Ck fuses and wire connections first. If no problem seen, get bike running and disconnect the ground cable @ battery. If bike dies the problem generally is in the stator or regulator assembly not keeping battery charged. Bike will run untill the battery is too low to keep the ignition system energized and the bike will die. If it continues running w/the ground disconnected, the battery could have a dead cell which will drain the battery in a very short time whether it is running or not.

Non Starting of Triumph Trophy 3

I think it is likely to be a flat battery - It would be worth topping it up and charging it for a long time then checking the voltage. You could try jump leads as well, but that doesn't work if the battery is really flat.

When a battery is left to go flat it often knackers it permanently (I know this to my cost!), they lose a percentage of their charge every day, especially if they get cold. If the bike isn't going to be used it's best to take it off, keep it indoors and charge it occasionally.
