Do you mean the floats? if so then take the carb apart again and inside the bottom half you will see 2 pieces of plastic on a spring number 22 on pic when you blow through the petrol intake pipe air will escape from near the floats when you lift them up the air will shut of which is what will happen when the carb is full of petrol if the air dosnt shut of the floats need adjusting bend the spring carefully upwards ( I DO MEAN CAREFULLY) then try again you may have to do this a few times untill you get it right

i would check the needle height first unscrew the throttle cable fromt the top of the carb watch out for the spring and you will see the needle inside the sleeve number 8 on the pic
the needle is number 7 remove the plastic washer from the bottom and pull the needle up a bit you willl see notches on the side of the needle just slide the washer down the side untill it clips into the one you want that will reduce the amount of petrol going into the carb

gas is going in to - 1stdcarb.jpg hope this helps

Runs good idle but when give gas cut off

sounds like a carburation problem to me
may be your choke is not switching off when you push the lever
and is seized where it joins the carburetor
get some light oil and lubricate the cable and take the choke mechs apart and clean it up then reassemble
cracked inlet manifold carburetor (connecting pipe)
it sounds like a damaged air filter or a cracked inlet manifold

if it is a cracked manifold
a quick get you home trick is to remove your carburetors
get 4 condoms put the condoms over the inlet manifold
cut holes in the end to refit your carbs
reassemble the bike
to get you home on the way home call in at your local motorcycle spares shop and order some new inlet manifolds

order a new air filter while you are there as well

hope this helps out

ride safe

I have a 99 ktm 250 sx. Had to get cylinder replated and a new piston. I put the bike back together and oil was leaking from the front lower end of the cylinder and i wont idle. Took the bike back ap

If there is a leak in the head gasket it will never run properly. Maybe the carburetor is plugged if it has sat for a while. The gas/oil mixture can go bad over time. The leak could be from a loose gas line. Or possibly even oil dripping from the oil filter if you just cleaned and re-oiled it.

If the bike had been sitting for a while and it was running but wouldn't hold idle, you likely need to remove the carburetors and thoroughly clean them. To confirm it's the carburetors you can use a spray bottle to spray a little gas into the carb throats and try cranking. If the engine fires up, your problem is definitely in the carbs; more than likely gummed up. Remember not to use steel objects if you're cleaning the jets because you will enlarge them as a result.

My bike wont idel but does everything else fine just when i come to a stop it stalls so i have to keep the revs up

If this is a new bike take it back to the dealer and have them properly set it up.
Sometimes a clogged air filter will cause the fuel/air mixture to become to rich and the bike will stall. Remove the filter and air blast it clean then wash wash in solvent/gasoline then let dry. Apply a very light oil to the filter to keep dirt out, then re-assemble.
Sometimes filters are in-expensive so just replace with new.
You also have a slide stop screw on the carburetor. This can be turned in about 1/8th of a turn to increase the idle speed.
Also: The throttle cable has adjustable ends both at the twist hand throttle and at the bottom where it goes into the carburetor. Vibrations may have loosened the adjustment and you may be able to re-secure the cable adjusters in the correct position for proper idle speed.
Best wishes,

2003 suzuki dr200se will not idle runs great if you keep it above idle. Removed carb, took it apart sprayed jets with carb cleaner. Reassembled and now will not fire. No gas??? Checked everything I can...

If the machine wont idle but the jets are clear, it is possible that you overlooked the carburetor body. If the passageways in the carburetor body are blocked , the machine still will not idle until you blow the body clear. Either there is still dirt in the carburetor, or the intake manifold is cracked or separated in a way that is causing too much air to get into the cylinder. perhaps a closer inspection is in order.

Carb help

I'm new to the site and new to carbs. I bought a bike last week that had been sitting in a barn for a couple years the engine hadn't been running in over a year. I was able to get it running the first day after cleaning out the field mouse home occupying the air filter chamber and swapping the old gas for new gas. The bike ran and idled fine but the left carb (dual carb setup Keihin) poured gas from the tube coming out the bottom. I did some research and found out the floats may be stuck. I went ahead and ordered new floats and float bowl gaskets. I took the carbs apart apart as much as I could, using Berryman parts cleaner to soak all the metal parts I could get off. I put everything back together and put the new floats in yesterday. I started the engine and not only is the gas is still pouring out the bottom of the left carb, but now the bike is idleing very fast. The idle adjustment is backed out completely. When putting the carbs back together, I screwed all the jets back in all the way. I screwed in the Pilot Air screw, the one with the spring, all the way in, then backed it out 1 1/2 turns. Not sure if this has anything to do with the idle. As far as the floats go, does it sound like I need to replace the float valves too? ,The seats on the jets, or the o-rings on the needle valves that the floats control are probably leaking.,,,
