If old gas sat in the carb.s for more than a month it starts to dry up. As it drys up it leaves behind a varnish like film that stops up some very small ports and pin holes inside a motorcycle carburetor. It is also very hard to get out. You can try this before you pull the carb.s for a full cleaning.Use a product called Seafoam, get as much gas out of the carb.s as you can. use a turkey baster and force the seafoam into your carb.s fuel line that you take loose from the fuel tank. Let that set for say 1 or 2 days. then hook up the fueltank with a mix of good gas and seafoam, (not a lot but enough to start it up. Move the cycle outside as the seafoam will make a lot of smoke if it does start up. If that does not clear up the problem you may have to pull the carb(s) and remove the blows to clean the inside. If you have to do that do not DO NOT MESS with any adjustment screws, DO NOT MESS with any adjustment screws. Just take the carb. bowl(s) off keep each one separate and number them so they do not get mixed up. do not mix up any internal parts. It is best to work on one at the time so nothing goes wrong. Work on a large sheet so if you drop a small part you can find it, you do not want to be missing some tiny spring or screw. Now, the fuel dumping out right now means one of the carbs needle and float is stuck open. You can try and tap on the carb bowl or bottom with a hammer handle to un-stick the float. Hope this Helps Fix Ya Up..

Why does gas pour out of my harley davidson mikuni carburator?


you probably let your bike sit for a while and your float is stuck in the carburetor,so try tapping lightly on the carburetor bowl at the bottom to see if it stops flowing .anyway it goes you probably looking at taking carburetor off and cleaning it out

It sounds like the float needle valves are lletting gas run into the bowl,in turn running gas into the motor,and fouling the spark plugs. Have you noticed if the oil level seems to be going UP,or the fuel level is going down? Kawasaki motorcycles are prone to leaking needle valves in the carbs for some reason. And the longer it sits,the worse its going to get.Try this,...pull the spark plugs and see if they are wet with fuel.Then,unhook the coils,and spin the motor over with the plugs out.If it shoots raw fuel about a foot out of each or ANY cylinder,then that is your problem. JUST BE SURE TO DISABLE THE COILS BEFORE SPINNING MOTOR OVER,AND DONT BE CLOSE TO THE PLUG HOLES WHEN YOU SPIN IT OVER!!
Good Luck!

Bike running rough at lower revs


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!!!!!)

I recently bought a 2004 klx 400 sr dual sport. the bike starts up with no problems. After i ride it for a few minute the bike starts to act like it is running out of gas then stalls. it will turn...


Hello
Your running out of gas.
the fuel filter needs replaced.
your fuel filter is clogged and isn't letting a full flow of gasoline through.
change your fuel filter.

Also check to make sure your gas tank vent isn't clogged.
a clogged gas tank vent with pull a vacuum and try to **** your tank in, but it can't, so your fuel flow stops if it can't breathe.

That should take care of your problem.
have a great weekend

The gas tank is full and thegas is not going to filter


Some older bikes (don't know what year yours is) have an engine vacuum line that allows fuel to run once the engine starts. (Starts with the fuel that was already sitting in the carb's) If you put a vacuum hand pump and start to pull vacuum, the fuel will flow...
Otherwise, something may be plugged.

93 fat boy will not continue to run once started and wont restart


sounds like a fuel supply problem it probably has some build up in the fuel system from sitting so much, if it has a screen in the bottom of the tank it could be clogged with sediment from the fuel sitting. or in the filter if it has one could be clogged with old gas or dirt particles. Clean the tank if needed, unhook fuel line at engine and make sure there is flow from the tank. I sometimes blow air through the line back up to the tank to back wash any problems.

good luck

SMELL OF GASE


sounds like your bike is running rich. Probably wouldn't hurt to have your carburetors adjusted and synchronized.

SMELL OF GAS


I have noticed that it smells of gas when it is running. Not really raw gas but kinda of exhausty gas it still as a bit a raw gas smell but it has an exhaust smell too. Also there is some slight smoking coming out of the exhaust pipes. Not too bad but if you look you can notice it. If I goose the throttle up it comes out more and the goes back to being light. Are these two problems related and what could be the cause? ounds like your bike is running rich. Probably wouldn't hurt to have your carburetors adjusted and synchronized.,,
