SOURCE: I have a suzuki drz 125l 2004 model that currently

okay theres a couple possable things that can cause this .... carbon on the valves, ran hard,not frequent oil changes, low on oil, cheap oil, spark plugg is too long , too much oil somtimes causes this,crank case breather plugged,it all depends on the way it was treated in the past or the present
i change my oil about every 15-20 hours keeps debre down and less friction on engine,remember this is not water cooled! so use the best 10-40 oil or atleast good known oil and run some seafoam through the gas,it will take that carbon off . and if you dont have a inline fuel filter u should get one they really save carbs and there only $3.00 at oreily! hope this helps <walker>

SOURCE: removing the carburator on a suzuki drz, 125.

It is quiet easy, you remove the seat then the fuel tank this will expose the carburetor then its simply a matter of disconecting fuel line and unscrewing attachement screws. why do you need to do this? I would be very careful doing this as any dirt or dust or grime getting in can have huge impact

Always turn the fuel petcock off when your not riding the bike.The cocks leak and the fuel flows through the carb. through the intake, into the cylinder, past the rings and into the crank. This is possible death to your top end. The fuel washes away the oil on the cylinder wall !
I would do an oil change then let the bike run for a little while then do another oil change.This will help get the fuel out of the crank.Then another change after your next ride.I would even put a little extra oil with your fuel mix to help lube that cylinder and maybe smootout the idle. Dont run the bike to hard for a while,let the oil clean up the cylinder.(I hope) You may have scorched the piston and cylinder walls with the fuel in the oil.

The carb on a DRZ 125 or KLX 125 comes pre-set from the factory with a very lean tuning. At first it may run well but once you get some time on it with a little build up and some dirt the lean setting gets even worse. To correct this you need to thoroughly clean the carb , specifically the fuel screw. Remove the carb from the intake and airbox rubbers and take off the slide cap. Drain the carb from all fuel. The fuel screw is in a recessed tube located on the bottom of the carb on the front side towards the cylinder. It may ahve a brass plug covering the screw. This is done at the factory to prevent tampering for emissions purposes. The plug can be removed by taking a very small drill bit 1/8" or so and very carefully drilling a hole in it. Put a small sheet metal screw in the hole and pull with pliers and it should come out. Make a note of the position of the screw and slowly turn it clockwise in to see what the setting is. Do not apply heavy pressure when you feel it getting tight stop. It is a soft brass screw with a fine point an is easy to damage. Typically the factory settings range from 1 1/2 to 2 turns out. This is way too lean for the bike to idle and run well or even start without the choke. back the screw out and remove the spring and O ring. Using carb cleaner with the hose attached insert it into the hole you just removed the crew from and spray it out. You should have a good stream of spray into the center bore of the carb. Re-insert the O ring and then the spring and fuel screw. turn it in until you feel it making contact and then note the position and back it out 3 1/2 turns. Put the carb back on and it should be able to start and run without the choke. Some bikes will still need a bit more tuning. The older carbs had a slide needle that had 3 to 5 positions on the needle that could be adjusted with the movable clip. Since this does not have that option you could go to a Yamaha dealer and buy the needle from a TTR 125 and install it as it is the same carb. This will cost you around $15.00. Or you could go to a hardware store and buy some 3/0 stainless washers and remove the needle and put 2 or 3 under it to shim the needle up just like the clip on an adjustable needle. You may spend $1.00 with this option. The bike should run better than new.

Hi, Aiden and the usual suspects are:
1. Severely discharged or a damaged battery must have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
2. Faulty alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Faulty main circuit breaker or ignition switch, check for loose connections and continuity.
5. Faulty system and or ignition relay, check for continuity.
6. Faulty ignition coil, ignition/electronic module.
7. Faulty CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Faulty neutral, side stand or clutch lever safety switch.
10. Fuel tank empty
11. Fuel tank contaminated with ethanol sludge.
12. Water or dirt in the fuel system, or clogged filter.
13. Restricted, blocked or kinked fuel line.
14. Faulty fuel pump.
15. Faulty pressure regulator.
16. Faulty or clogged fuel injectors.
17. Lean angle switch is faulty or needs adjustment.

2005 drz 125L carb hose line diagram

Might be fuel leaking from overflow. Perhaps the float valve is stuck or damaged, allowing the float bowl to overfill. Slight chance tapping on side of carb may seat the valve. If not, it will probably have to either be set, or replaced. Could possibly have some "gunk" stuck in the valve seat from the cleaning. It only takes a tiny speck of debris to hold the valve open, causing flooding. Another possible cause is that during the cleaning, the tab that adjusts the level of the float valve got bumped, changing the level.

it sounds as if you undid the oil pump plug and if you put everything back in as it came out you will be fine.
