    It will get hot, that's where the hot gases that have just exploded in your engine are going... if it wasn't, your engine would get hotter and hotter till it melted.

    As to the bike dieing, what has changed?
    How long has this problem been there?
    When was the last time the bike had a service?

The engine is supposed to get hot. ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine.

Please rate this solution. Thanks!

I HAVE A HONDA 2005 HONDA SHADOW AERO. RAN FINE YESTER DAY. WENT TO START IT THIS MORNING AND FORGOT TO PULL OUT CHOKE IT STARTED THEN DIED. PULLED THE CHOKE STARTED UP AND RAN FOR 45 SECONDS AND THEN...


You have 2 solutions : take out the spark plugs and dry them with cloth, put them back in and start the bike.
Or, leave the bike over the night and the excess fuel on spark plugs will evaporate.
If the engine is hot and you have this problem, just leave the bike for half an hour and start it.

Hi, Anonymous and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.

3. Fuel line pinched or kinked.

6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting screw set too low.

How to start yamaha yz 400f?


pull the choke out, make sure fuel is on, DO NOT turn the throttle before starting. now you have to make sure the cylinder is at the top of the stroke, give the bike a couple short, easy kicks your not trying to kick it over yet, you are just trying to get the piston to the top of the cylinder, as your givivng it the short easy kicks, you will notice that the kick is getting shorter and harded......until you are at the top of the stroke....now it is ready to kick over, hold the hot start lever in about half way to release some compressionand give it a hard strong kick, if it doesnt start on that kick, make sure you are at the top of the cylinder again and when you are, give it another strong hard kick all the way to the bottom, when it starts immediatly release the decompression lever or you could do damage to the valves. relaese the choke, you dont want to leave the choke on too long because it is a very rich gas mixture and will eat the oil off the cylinder walls after a while. and DO NOT high rev the bike until it is warm, because you need to make sure that oil has gotten to the top end. it isnt a 2 stroke, ya cant make her screem right away.

My troybuilt yard pony riding lawnmower will start with the choke fully open and then dies immediatly when you take the choke off. It will only start and run with the choke fully open, but dies after 20-30...


Do you mean that you can start it normally using the choke (that would be choke CLOSED), but then it dies immediately when you move it to run (that would be choke OPEN)? And if you leave the choke in the starting position that it dies after 20-30 seconds?----- If I have that all right, then you definitely have a restriction in the gas supply. Drain all of the gas from the mower and don't use any old gas. If you have any more old gas (from last season) don't use it. If this mower has a gas filter, replace it. Put just a little fresh gas in the tank plus a little of the cleaner. Start it up, do that a few times if needed. Use a fuel additive such as Sea Foam to keep the gas from gumming up so fast.

Choke problem


Hi, Cnizio if you take your bike to a dealer for a specific issue that costs outrageous amounts of money only to have the same problem 2 days later your situation is not unique unfortunately and it is a double edged sword. First, you suffer the emotional stress and frustration of spending all your hard earned "Drachma" and your bike does not get fixed. Second, comes the realization that not only are the technicians incompetent but also the service manager for not doing anything about it, this isn't rocket science, it's a glorified lawn mower engine with extra cylinders and carburetors sometimes. You need to put an end to all the double talk, dancing around the issue, and a we don't care attitude, but how you ask, very simple you exercise the "nuclear option" go back to the dealer and ask to speak to the owner or general manager if the owner is not there, then with a straight face and polite voice you ask him/her if they can provide you with the name and contact phone number of the person at your brand motorcycle headquarters in your country that can recommend a repair facility that will fix your bike because your local dealer either can not or will not. I guarantee you that is all the grease you need to get someone to light a fire under the proper persons rear end to resolve your issue "toot sweet" For more information about your issue and valuable "FREE" downloads that you will need please click on the blue links below.

sounds like you have a blocked jet in your carb you need to get it cleaned and a new spark plug would help.

Starting problems


Check the compression. If it has low compression it will always be difficult to start. I have the same bike. It is a really good starter, comparatively to other older 'cycles I own. 1) Check the fuel level in the tank, and be sure to turn the fuel switch (left side of bike below tank and seat) to On, or even Reserve 2) In stock tuning, my bike likes full choke for cold start, in any ambient temperature, it likes to warm up with the choke on, until it starts to sputter from the rich mixture. 3) I believe this bike has vacuume tube that goes to the fuel petcock, this shuts off fuel to carbs when bike is not running. Thus if the bike has not run in a while, or the carbs drained, it will take several start attempts to get the carb float bowls filled. 4) This bike is hard to start if the battery is old or marginally charged. 5) Also pull the spark plugs, if they are brown, or black, change them. 6) check the air cleaner, if it is too dirty it will essentially act like a choke
