I have a RM 125, the carb is leaking fuel out of the overflow. I checked the carb multiple times and also checked the float and needles. If anyone has suggestions to stop the leaking feel free to ask.

If it is leaking out of the overflow, then either the float is set for the wrong height of fuel in the bowl, or the needle that shuts off the flow is missing, or there is something stuck in the jet. The best thikng to do is to take it off the boike completely and strip it on a bench. You will need the workshop manual to check all the parts are there and to find the float height.

Wow, everything is in this manual! Section 4 - 2

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.

Suzki ozark 250 cleaned out tank and carb runs but will not idle

sounds like the float is not working properly , could also be the jet. would be a good idea to buy a carb kit, not very expensive and save a lot of grief.

03' rm 250 fouls plug in seconds.?

You need to ensure that your fuel/oil mixture is correct. Roughly between 40:1 and 32:1. Usually if you mix is off, it will foul plugs quickly. You can also get a compression test and if it fails look into getting a top end done. Any motorbike shop will be willing to do it and is generally inexpensive. It would be cheaper to do it yourself, assuming you are somewhat mechanically inclined and have the service manual. Good luck.22

2003 rm 250 while holding gas at mid throttle it spudders

Install a new NGK spark plug ONE HEAT RANGE HOTTER THAN STOCK . Now go back to the 32/1 gas mix. The 32/1 is what lubricates the crank bearings and piston. At 44/1 you are asking for a seized piston and/or the need for new crank bearings. Be sure to use Two Stroke Engine Oil in the gas, NOT motor oil. Use premium gas, not regular. This should take care of plug fouling.

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 all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw 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. This process should get you back on the road.

Please rate this solution as " FixYa " if all goes well. Thanks
