Speedfight 2 won`t start up now

SOURCE: jammed steering lock

Move the steering left and right while turning the key. If any pressure is on the lock pin then the pin can't slide freely. With pressure on the lock pin the key will feel like it will not turn to unlock.

Hope this helps. Please rate this solution. Thanks

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. 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 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. If not, then remove the slide from the carb and move the clip on the jet needle one notch lower.

Please rate this solution. Thanks hanoidan2005!

Could also be a bad rectifier not sending the proper voltage back to the battery for charging or you just got a bad battery. Since you just put in a new battery I'd suspect that and have it checked at the shop you bought it from.

When the red light comes on, eg (F1) use these fault codes to find your problem. To extract the codes from the computer system, there is a two pinned connector hanging out of the wiring harness, on the left hand rear of the bike, (say above the pillion foot peg under rear trim. Be sure not to confuse the other connector used by the Suzuki Workshop Mechanics, as this has four or five wires to the connector) After locating the one with only two wires at the back, use a split pin or paper clip to bridge the two wires togeather and turn the ignition to the ON position. You should now be able to read the code on the console. The fault codes are as follows,,

Did they check the plug wirers? How about the gas? Drian the tank to remove any sediment, OR, Put in an additive that has dry gas in it to remove any condensation. Change the fuel filter,
