More that likely when you fell the lines to the carb got damaged or partially disconnected and are leaking or the carbs(if it has carbs) has a stuck float which would allow fuel to over fill the bowl and pour out. The petcock is a vacuum controlled unit so that's why it does not put out any fuel until the engine is started (which is when it leaks). The tank may need to be lifted up some to see where the leak is coming from. If the lines are ruptured then replace them. If the carbs are leaking, tap on the bottom of the bowls with the back side of a wooden hammer (or something soft) and sometimes that will make them stop leaking.

SOURCE: wet clutch

I just recently experienced the same thing.  I drained all the fluid out of the clutch master throught the slave cylinder and refilled it with new fluid.  Bled the system really good and now it works just like new.  If this does not help you may need to remove the slave cylinder and replace the seals if it is leaking.
Good luck1

SOURCE: Starting The Bike On A Cold Morning

Try putting in new, stock spark plugs. Check and possibly replace the air filter. Charge the battery. Get the bike running then check the battery voltage at 2000 rpm. It should show 14volts or more. If not, get the charging system checked. Get a can of starting spray (for future problems).

Get the compression checked. Your bike is 21 years old and I will bet that the valves are needing to be reseated. Check the valve clearances with a cold engine and reset valve clearances as needed. Check the area where the head contacts th cylinder. Any mist of an oil stain? Tighten the head or replace the head gasket. If replacing the gasket, now is the time to have the shop lap re-seat the valves. Have them sync and balance the carbs as well. Your bike will now have its' manners back and show you the dedication it should.

I would be suspicious that you have not been drained . Put say 5 gallons in the tank and see what happens . The next possible problem is the fuel pressure regulator and the fuel pressure sensor that would result in you problem

How to store your motorcycle for winter. Storing your motorcycle.


As the summer months start to come in, we all like to get our motorcycles out and start riding them, but i hear a lot of people saying help, my bike wont start! That is because when you last parked it in the shed for the start of winter, then you made no preparations. With a few simple steps, next summer, you can get your bike out, and fire it up without any problems, ready to ride. There are things you must do when you go into storage, and a few things to do when you bring your bike out.
OK,so winter is approaching, and you want to put your bike away in the shed.
First thing you need to do is drain some fluids. Drain your engine oil. Then drain your gas tank and carburetors. It is important to drain the carbys, as the fuel left in the float bowl will go bad. You can choose to totally drain your gas tank, or fill it to the top with gas. Storing a tank full with gas, leaves no room for moisture to form, causing rust on the inside of steel tanks. Next, you need to also disconnect one lead from your battery, or even better, if you have a trickle charger hooked up to it. Thats about it really. Also,if you are confident in doing so, remove spark plug, or plugs, and spray some penetrating oil down into each cylinder, turn engine over to work it through. This will prevent any moisture or corrosion from forming on the inside of your cylinders. It is also a good idea to clean or replace your spark plugs each year anyway.
Now it's summer, and you want to ride, just roll your bike out. Put in some fresh engine oil, a fresh tank of gas, and a fully charged battery, you are ready to go!

My hyosung wont start, it was running fine until it was parked in the shed for approx 3 months, now it wont start! It seems like a fuel problem, it will start and rev when we squirt fuel into the...


Hello and thanks for the question.
It sounds like the carbs are not getting fuel to the engine. This is common with the fuel that we get now. the fuel is not stable and can gum up quickly. I have seen carbs become clogged in as little as 60 days.

The first thing to do is drain the old fuel out of the tank and the carbs. There is a drain screw at the bottom of the carbs and you can drain the fuel out by loosening the screw. Make sure that you are carefull when draining the fuel out so that you dont have excess fuel leaking everywhere. I usually put a small container uinder the drains.

Syphon the fuel from the tank and replace with fresh fuel.

After all this is done try and start the bike and run on choke for a while. the fresh fuel can help to flush the old gas out. If the bike does not run properly the tank and carbs may need to be cleaned. The carbs are very detailed and should only be worked on by a qualified technician.
Thanks and I hope tht his helps.
Steve

My Suzuki AX100, 2009 model started stalling when I shifted down and also it was really tough to start (kick start), so I had the carborador cleaned. It started so smoothly right after and I toured around...


1. Have you recently replaced the air filter element?
2. Drain all fuel from tank, lines before installing renewed carburaetor then fill the bike again see what happend.
3. Make sure that when filling up no oter debris or dirt got into your tank.
4.Is your choke auto or manual? If manual ensure that it is normal after riding around as it foul up your air mixture ratio.
Good enough, please return a comment. Thanks

try a little starting fluid in a carb see if fires if the bike fires up then dies then start checking for fuel line from tank to carb for flowing if it gets down to the carbs and not flowing (not sure if your bike includes a auto fuel shut off or not) but the problem could reside in this location otherwise there could be water in the fuel bowls in which case you drain the cups hope this helps to trace down your problem

My 50 cc dirt bike is messed up will start but won't runbutabout 10 seconds the engine bogs up then shuts down


Hi and welcome to FixYa,

Initially, determine the quantity and quality of the fuel by loosening the drain screw and catching the fuel draining. Additionally, determine if there is spark right after "engine bogs up then shuts down".

The "quantity and quality of the fuel" would be indicative if the fuel is contaminated and/or if there is sufficient fuel in the carb's bowl to run the engine above 10 seconds. Checking for the presence / absence of spark after the engine quits would help you determine if it is an electrical problem or a fuel starvation issue.

Good luck and thank you for asking FixYa.

Engine misfire and cutting out when running at normal engine temp


Make sure your fuel tank vent is not plugged. To see if this is the problem, the next time the bike starts acting up, stop and open the fuel tank. If you hear a whoosh of air being sucked in you know your vent is plugged.

The C8HA is still available, it is NGK stock number 2168.
Good luck.
