How to remove gas tank from gz 250 - 2000 Suzuki GZ 250 Marauder

YOU HAVE TO DROP TANK OUT. AND THEN IT IS HELD ON BY TABS AND YOU HAVE TO DRIVE IT TO THE LEFT TO LOOSEN.. USE A BIG FLAT HEAD AND HAMMER / RIGHT TIGHTY AND LEFTY LOOSEY..

First remove the speedometer housing by removing the small screw below the speedo. remove the bolte at the front and rear of the tank.
Lifting the tank and tilting it, remove the three lines going to the bottom and front of the tank. Remember where they go,(mark them if necessary). Carefully lift tank free of bike frame. Check large rubber pads (if installed) and reinstall them as found.

Drain the carb with the gas valve on the tank turned off. Now turn the valve back on and see if gas again begins to flow out of the float bowl. If no gas drains with the valve open then remove the fuel line at the carb and check to see that fuel flows freely through the fuel line. If gas flows freely out of the fuel line then the float needle is stuck closed or trash is plugging up the needle jet assembly. If so, remove the float bowl and free up the needle. Use spray carb cleaner and the little "straw" that comes with the can to direct the spray into the float needle fitting. Fuel should flow when the float is down and stop flowing when the float is lifted. Pull a spark plug and ground the metal against the cylinder. Check for spark. If there is no spark then check the operation of the kill switch on the side stand and the handlebar. Use a multimeter to check the switches. Get fresh gas and install an in-line fuel filter to keep any trash out of the carb. Clean the air filter. Please rate my answer. Thanks.

If it has only sat for a week, then your not in any real trouble. As long as your seals are good and no water has leaked into the gas tank, then it should be able to start right up.

You will need to remove and clean the carbs on the machine. Old fuel can clog a the jets causeing the problem you are experiencing. You may also want to change the spark plugs due to running it while the carbs are not right it can foul out the plugs.

Here ya' go mate...this site has the whole bike in sections, exploded views and parts lists....go for it!
Cheers.

This is a shot in the dark but a potential "fix" that won't cost anything to try is to drain the carbs. Water can condensate in the gas tank and collect in the gas tank ( at the gas valve ) and carb float bowls. Since water does not burn well as a fuel, it can cause sputtering and uneven running. Enough water build up and the bike won't run at all.

remove seat and undo 2 ten mil bolts lift tank and gently slide it away but first remove fuel line.

remove the tank and find out what popped. could be a fire hazard.

I assume you have checked and that you do have spark.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

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 into all the little airways and fittings in the carb. Remove the idle screw and the air screw 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.
