If you don't want to spend alot of money. You might try just pouring some kind of leak stop into the oil fill cap. And let it transfer through.

2009 vulcan 1700 won't start. ran a week ago. has half tank of gas.

It turns over, with no start. It will either be fuel or ignition.
I understand from your description this machine has been sitting for some time. If the fuel is over a year old, drain it and flush the tank and carburetor. There is a lot of residue that occurs from evaporated fuel, mostly varnish.
Check the ignition by pulling a spark plug wire and visually verify the spark to the frame.
Remove and clean and set the spark plugs and re-torque.

Coolant is leaking from weep hole. I replaced both oil seals, gaskets (case and water pump) impeller shaft and bearings. Only thing I didnt replace was the impeller itself.

I have a 2005 with only 3000 miles on it. I could not start the bike and thought my original battery was weak. I had it on a trickle charger with a green light, but as soon as I tried to start the bike a...

As this point you can't get the bike to turn over is this correct? If the engine is turning over but won't start then yes the gas is most likely the problem. Gas after sitting for even a month can evaporate from the fuel system and it leave a fouls smelling deposit behind that clogs up everything. It stinks and it's a mess to clean out. To prevent this from happening use a product that is called "Fuel Stabilizer" in the last few tanks of gas before you put the bike away for the winter or a dormant period. If the motorcycle is in a hot climate or heated garage this foul smelling gas can happen within a few weeks.

My bikes been standing for a couple of months and its been started and stopped but not ridden and now the engine oil is now white how do i cure it

If your bike sits outside it can be moisture build up inside the engine. White oil indicates water in the oil. I would recommend changing the oil prior to riding the bike. Make sure that you check the coolant level to verify that it is not low. Warm the engine up and then drain the oil. The will help flush the moisture out of the engine. Once you have new oil in the engine go for a ride and check the oil again. If you still have moisture in the engine it may have additional problems such as water pump seal or even a head gasket issue.

Thanks and I hope that this helps.

I have a Yamaha R15 motorcycle.I havent ridden it for a couple of months. I tried starting it up but the engine does not turn over.The lights and horn works bur the engine does not start up . what should i...

First thing I'd do is charge the battery. Whilst there may be some residual charge left in it after 2 months or more, which is why you'll get a peep out of the horn and maybe some glimmer in the lights, there is probably insufficient power for the starter motor to turn over the engine which will be a very high current drain in comparison. Of course you could always try bump-starting it. Just need someone to give you a good push unless you live on a steep hill.
Hope this helps

Leaking battery

Yuasa batteries are expensive but with good reason. They are extremely high quality and follow the old adage 'you get what you pay for'.
Cheap batteries appear initial good 'value' but the extra investment will pay dividends long-term, if properly maintained, your Yuasa will last many years.

If you suspect the liquid is acid, neutralize it with some baking soda just to be sure. You don't want that dripping onto anything metal or pain, causing damage.
Once you have it neutralized, wash it out with water.

It sounds like you ride infrequently and bike may have periods of serveral weeks on occasion without being ridden.

My recommendation would be to install a quality replacement (like the OEM Yuasa) then purchase a battery maintainer that you can plug in while bike is not being used. Good maintainers are Optimate and Battery Tender. (I have both myself - I really like the Optimate 4.) Both of these come with a waterproof 'pigtail' harness that you can permanently connect to the battery - then when you put the bike away, you can simply connect up to it without having to remove anything.

Hope this is helpful.

Good Luck!!

2006 Aprilia RS125 doesnt start

Hi .... Try switching the petrol off just prior to stopping the engine and start up again with the petrol OFF. There's enough petrol in the carb to start the bike. A good battery should show over 12 volts. Take the plugs out and give them a good clean or replace them. Is there a petrul pump fitted ? A two stroke needs to be ridden quite hard to maintain efficeincy, higher revs etc ........ let us know how you get on ?

Hayabusa engine griding sound

If you have done 14,500KM since the noise started there can't be a whole lot wrong. They are noisy engines anyway - might be normal. Only thing I can suggest is to check under your clutch cover.
