TIP My bike had a leak in the fuel tank and I had to replace it. This took several months and now that the new tank is on and I had to buy a new battery, I still cannot get it to crank after sitting up so long. Does anyone have any tips on how I could get it cranked so I can get back on the road?

Hey, did you try setting the petcock on Prime for a few seconds? If not, this might help get some gas back in the carburetors. Leave it on Prime for maybe 15 seconds, then choke it and start like you usually do. Once it starts, set it back to Run or On.

Bad gas and motorcycles

As you all have noticed lately the gas we are getting with the additives and ethonal and no telling what is in it. the gas is playing havic of motorcycles with the clogged carburators, stuck fuel injectors, locked up fuel pumps, sticking valves so on and so forth.
my tip for all motorcycle riders is that most motorcycles benifit from running hi-test fuel in them. but all fuel is not the same and if you find your bike not running so good on the fuel you are using, change it! go to another station buy gas from different staions untill you find one that your bike runs good on. never park your bike with a empty tank! the more air in your tank the faster the fuel will go bad on you, so always store your bike with a full tank of gas and you will have a better chance of the gas not going bad on you. when you find your self out on the road with no gas staions to chouse from and have to get gas, be aware if you have to get gas from the little hole in the wall mom and pop gas staion in the middle of nowhere DO NOT BUY HI-TEST!! these stations do not sell a lot of hi-test and the fuel in there tanks could be 6 months old or more just waiting for you to pump it on your tank and do damage to your fuel system so buy just enough regular to get you back to a well traveled station that you can fill you tank with good fresh hi-test fuel.

Haven't had it out much, but after an hour of hwy driving, one cylinder, i think stopped working. trailered it home? any ideas

If the fuel in the tank sat for more than six months, it separated and fouled a spark plug. Common problem for motorcycles that get stored in the wintertime. Replace ALL FUEL, use a CLEANING ADDITIVE with the first tank of new fuel, and REPLACE THE SPARK PLUGS.

If you must store the motorcycle in cold months, EMPTY THE GAS TANK before storage, and put new fuel in when putting the bike back into use.

Fuel leak from carburettor

No need to buy a new carb. Simply clean it and or replace the float needle valve. Check float level also after replacing the float needle valve. Most of the time the carb gums up and causes this to happen when sitting for a long time without being run. If you are going to store your bike for a while. Drain all the fuel from the carbs and gas tank before storing. You can also use a gas stabilizer in not setting up more than 3 months.

Hi i have left side leaking carb after sitting for a while. What would be the issue

I do a lot of small engine repairs, and commonly when the fuel is cut on and the carb starts to leak, your float is stuck open. you said that it has been sitting for a while., How long? Over a period of a couple months, condensation will start to build up in your tank and carb float bowl, with this happening it starts to build up corrosion and electrolysis. To fix this problem :: 1 drain your tanke completely. 2 remove the carb float bowl from one or both carbs ( however many your bike has) ((DON'T LOSE THE GASKET) 3 carefully remove the pin holding the float in, and when you remove it be careful, there is another little pin with a rubber tip attached to the float 4 clean them thoroughly, pins and float, 5 clean inside float housing 6 Reassemble, carefully in exact order you took it apart. 7 fill tank with fresh gas and add 2 ounces of STABIL water remover and fuel treatment. This should fix your problem.. Let me know how it goes

Hello Colin, the fuel leak from the upper hose would indicate excessive gas due to flooding, as you stated. It could be the float has stuck and not letting the float valve close to stop the fuel flow. This happens a lot when a bike is stored... Other possibilities - The float could have a pinhole in it causing a high fuel level, or not adjusted properly. Also, make sure the choke is not stuck partially closed. Remember, a "wet" gas soaked spark plug will not fire, so it's best to replace the plugs after they have been flooded or fouled. I hope this information is helpful.

Hi, Mitchmnd if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will not idle or run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition and in the future pour in a bottle of fuel stabilizer and injector cleaner for you FI folks at least 2 times a year and before storage.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or more, any readings in the 11 volt range you need to do a proper "LOAD" test on the battery and replace as necessary, you may have 12.5 volts or better but little or zero amps, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Check intake manifold and seals for leaks and cracks.
8. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
9. Replace spark plugs with new ones and check for spark.

My 1974 kawasaki ke 125 is leaking gas out the bottom of the engine. what is wrong with it?

Several things could be wrong. First, the fuel petcock (valve) at the bottom of the gas tank should be turned off when the bike is not being ridden. Also, it is possible the valve may not be fully shutting off the gas. This can allow the carb to overflow and leak gas. A stuck open or punctured float in the carb bowl can cause overflow. The float should be light as a feather and have nothing inside it but air. Is the carb securely mounted?

Check for cracked fuel hose or bad connections at the tank and carb. Is the fuel valve body leaking gas where it mounts to the tank? Heck, with the bike being 36 years old the tank may be leaking at a weld or due to rust through. I wish I could work on your bike. The older bikes are more fun to work on than the newer bikes. Post a reply and let me know what you find.

Fuel Lines leak where they pass through opening into tank

i had the same problem with my trimmer. you could replace the fuel line but if you don't want to hassle with fishing it thru the hole i suggest going to and ordering the gas tank. it only cost me $18 with shipping and came with everything (tank, lines-with fuel filter, and gas cap). all you need to do is take out the 4 bolts on back of trimmer and the 2 top bolts holding the housing together. be careful not to nick any gaskets especially the one behind the 4 bolts. this is the crankcase gasket. also don't get anything in the crankcase that will score it as this will ruin the trimmer. also there are 3 spacer gaskets that go in the holes in the fuel tank and i believe a plastic heat shield between the gas tank and the bottom of the trimmer. you will see this when you take the tank off. just be careful and be sure all the bolts get tightend up (especially the 4 on the back as this is the back side of the crankcase). it only took me 15 min to replace it and the trimmer runs great. all the above info is if you have a trimmer with the gas tank on bottom. if the tank and gas cap are on top hopefully someone else will be able to help.

good luck
