How do I remove and clean the carburettor of this bike?

  • Anonymous Mar 16, 2014

    When I start the bike and switch the fuel tap on, the fuel starts flowing out of the overflow pipe as if the fuel pump is pumping the fuel out directly or the needle and seat are not closing off? Both carbs were removed and thuroughly cleaned out. The bike worked perfectly for 5 days and suddenly developed this problem on the 6th morning. What could the problem be?

Looking at that bike. Seat off, tank off ,side covers etc.Turn off fuel remove fuel line, loosen motor side and air filter side pipe clamps. then remove carby from bike Unscrew plunger on top disconnect throttle cable from plunger

Most *** Carby's are the same I use any bike book or Manuel to gather info on how to disassemble and assemble.

are sensitive things if you are not sure on how to inspect and clean properly take it to a pro.

When turn on petrol and kick bike, petrol is running out of overflow pipe on carb and bike wont start, and bike sounds flooded.

You have a sticking float in the carburator, due to old gas, or dirt. The float moves a needle that turns on and off the flow of fuel into the carb bowl.

2005 suzuki wont stay running, i had just bought it and it will start but putt around but cant reach high rpms. does the carburetor need to be cleaned?

Remove the carb from the bike.
Completely disassemble the carb
Soak all jets, needles, springs, screws and carb body in a carb solution overnight.
Do Not soak any o-rings or the float. Clean the float with a brush, and replace the o-rings if they are flat.
Rinse with water and then blow everything out with compressed air.
Make sure you can see through the jets and the small holes on the side of the jets.
Make sure you blow through every hole in the carb body.
Reassemble carb, mount on bike.
It will run like new again.

NOTE: When removing the air/fuel mixture screw, turn it in(clockwise) until it stops and STOP turning, Do Not try to tighten any further.
Count the number of turns it took to stop. Write it down so you dont forget overnight. Remove it for cleaning.
When you reassemble the carb, turn the air/fuel mixture screw in until it stops.
Now turn it out(counterclockwise) the number of turn you counted.
If your not sure turn it out 2 turns.

Suzuki gn 125 lacking power

I assume you dumped out the half pint of old gas and rinsed out the tank. Get a new spark plug and clean the air filter. Remove the carb and dis-assemble it then soak the parts in denatured alcohol for 30 minutes. Do not soak the rubber diaphragm. Finish the cleaning with a can of spray carb cleaner from the auto parts store. Be sure all internal fuel and air circuits are clear and that the diaphragm is not torn or has pin holes. The top cap must have a good seal. Go to to see a diagram of the carb and the rest of the bike. It looks like they have lots of parts for your bike.

Bike wont idle unless the choke is on.

Try cleaning pilot jets on carb or carbs. Also check for vaccume leaks like hose off of carb or bad carb boots.Spray carb cleaner around boots with bike running but be careful not to get it near exhaust or spark plug.

How do I service my carburettor? The bike has been standing for a while and struggles to start, and doesn't start at all

The carburetor assembly is between the air filter assembly and the engine, Usually there are hose clamps that connect the carbs to the air filter housing, loosen these and see if you can pull the air filter assembly away (just a little space required).

**Before you do the same with the carb assembly where it connects to the engine, take note of the remaining items holding the carb assembly in place:

** Your accelerator cable (and possibly decelerator cable
**Fuel hose(s) coming from fuel tank

and THEN see if you can remove these before you remove the carb assembly-take note of which one went where, how it was routed, etc.

Pull the carb assembly out and work on it over a suitable drain pan, as fuel will surely drain out.

Take the bottom bowls off (4 screws each) and remove all the little parts. If you work on this over your drain pan, you will not lose anything that surprises you by falling out of it.Clean it out with a carburetor cleaner spray like GUMOUT. Might have to scrub with a tiny brush or pad in certain spots. Also be *very* careful when you get to cleaning the jets out-these are very precision and are most likely the cause of your no-start problem.

Just a very careful and thorough disassembly, cleaning, and reassembly should get you up and running.

Hope this helps.

Bike will not idle

Remove and clean the carb. Reassemble then adjust the pilot screw. This screw is on the bottom outside of the carb centered L & R and forward of the main jet. The screw is nearly recessed in the carb. Turn the screw out 1/2 turn to richen the mixture if the cleaning alone doesn't do the trick. Also, move the clip on the jet needle down one notch for better low speed response. Reset the idle speed as needed.

Problem start bike. Push a starter and only clik , bike wont start. Suzuki 250gc 2004

Sounds like a bad battery. Try charging overnight with a 1 or 2 amp charger.
If this doesn't help then go to the dealer and ask for the stock plugs for your bike. Check for spark on each of the new plugs then install the plugs.

Remove the carbs , dissemble it and clean the varnish out. Remove the petcock, ( gas valve ),water trap and clean it out. Next let one cup of gas flow into a container. Any water or rust in the bottom of the container? If any rust was in the water trap or the container then purchase an inline fuel filter to eliminate the rust getting into the carb.

If cleaning the carb yourself does not do the trick then take it to the dealer and have them clean it and install a carb kit. This should eliminate the carb as a problem. Get a new air filter and install it.

Now you have spark, gas and air. If it still will not start it is likely that you need new crank seals. On a bike that old you may well need new crank bearings as well.
