Question about 2003 Suzuki GZ 125 Marauder

Open Question

I have a 2006 Suzuki gz125 it leeks out the bottom of the carb when switch off after running. My mate says the float is stuck. How easy is it for an amateur mechanic to fix this. Would this also cause the bike to lose power.

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.

SOURCE: Cleaning carbs on Suzuki GS650 L, what is the float setting?

to check the float height, invert the carb body holding the float arm pin so the pin will not slip off. With the float arm kept free, measure the height it should be 22.4 + or - 1.0mm
This is what the shop manual says.
basically what that means turn the float bowl upside down and keep the bottom of the float even with the edge of the bowl.

it sounds to me like the carb float levels are out of adjustment and it is overfilling the bowls,or,the needle valve seats are worn and leaking,which will allow fuel to continue filling the bowls even though it looks like they are closed,remove the carbs from the bike,remove the bowls,turn the cabs upside down close the floats(push them right to the top,this simulates full bowls)then blow throgh the fuel inlet pipe,if you can hear air escaping from around the seats they are faulty,also check that the seats themselves are tight in the carb body,i dont know why but gsxr carbs seem to shake the valve seats loose..hope this helps

SOURCE: Float setting for BS34ss carb

I have a set my float to 22.0 +- 1.0 for a Mikuni carb.
To set floats, drain the carbs, pull the carbs from the bike invert and remove float bowl.
With the carb inverted, take off the float bowls. Take off the gasket. Use a vernier caliper or an accurate device to measure from the carb body to the top of the float block.
Here is are a couple of good sites about carbs and such.

You only have three options as to what is wrong. Either the float is stuck, adjusted wrong or trash is not letting the float needle close fully. My bet is trash from the gas tank.

Flooding xj900

Hi I had the same problem after rebuilding my CB900 carbies a few years back.

The floats hang down so far in the carb that they actually get stuck down even when the fuel flows in after a rebuild.

Turn the fuel on and tap the bowls with the handle of a screw driver (plastic) I used a long shaft screw driver that way you can pretty much get all of them from one side.

This light tapping jults the floats and it allows them to pop up with the pressure of the full bowls if helps with them moving.

Hope this helps.

Suzuki 800, 1997 carb floats stuck

the floats are easy to fix...getting to them is the problem. the old gass has gone bad and will not ease up if new gass added.
remove carbs undo the 4 retaining bolts on the bottom of the carbs spray with carb cleaner free them up by hand (try not to adjust anything) and replace on bike !

sounds like your floats are faulty in the bottom of the carbie you have a float which controls the amount of fuel allowed to enter the bowl you can test this by taking it out and bending it by a degree

Hi ive a rm 250 and its constontly leaking petrol from the over flow on the carb wen the petrol is turned on its happing wen the bike is running and turned off please help??

The float in carb is stuck open. Remove the float bowl at the bottom of the carb dump out the fuel and trash in the bowl then use spray carb cleaner on the float needle area while gently lifting and releasing the float. Put it back together and try it. If the problem continues, remove the float and shake it. Anything inside the float? A crack in a seam on the float can let fuel/water into the float. This kills the ability of the float to shut off the fuel feed to the carb. Consider installing an in-line fuel filter to prevent future problems.

My oil smells like gas on my 2005 gsxr 600 i just bought

hi,if the bike is a carb model,you may have a leeking float needle seal,this is quite common,basically if the float needles leak they will allow fuel to flow unchecked into the carb,ultimately flooding the carb,the fuel then runs down the inlet manifold and into the sump,hope this helps...cheers

Runs for awhile then stalls and petrol fluds out through one air filter carb

The float in the carb is sitcking open and the carbs should really be rebuilt. The float will open when the fuel in the carb is low and when the carb fills up -the float will raise up shutting off fuel to the carb. You can try turning on the fuel on the tank and take a long blunt object and actually knock on the bottom of the carb and try to release the stuck float. If the carbs are half way decent then this will probably work. If they are "gummed up" then removal and cleaning is necissary. I hope this helps -I've encountered many of these-hope this helps!

I have excess fuel running out of overflo tubes. I think I have a stuck float or needle valve. Is there any resolution short of pulling carbs?

hi mate yes you have a stuck float or it needs adjusting in order to do this you need to take the carb off and then undo the screws on the bottom and the bowl will come off and in there will be your float see if is moving freely if not unfree it and if it seems to be fine you need to take the pivot pin out and then the float will come out with the inlet fuel valve still connected take the inlet fuel valve off it is held on by a wire cage which will slide off the tab then you need to bend the tab downwards a bit this will decrease the amount of fuel going into the bowl and stop it from going out the over flow a picture below will demonstrate mate5f8e07b.jpg

The carberater is leakin gas

hi mate you float is to high in the carb take the carb off and take the bottom casing off and adjust the float to the correct measurements in the manual if the float is too high it is allowing to much fuel in and so it will flow over the over flow and out the tubes it is simple puch the pin out and adjust the metal where the little valve is hanging onto with a pair of long nose pliers good luck

Gas problems

The flow bowl is stuck. Easy to fix. Take the carb off and take it and dump it unside down. Re-install and check it out. Or you can try to tap on the flow bowl on the carb. Float bowl is on bottom of carb, it is screwed in by 4 screws.
