SOURCE: the bike was stolen, replaced the ignition lock, now won't start
well it depends on what kinda of bike your talking about.like on my cbr600rr it has a tip over switch which wont send spark to the engine and you have to replace it.some bikes you can just reset the ecu.i would get a service manual and find out how to reset the ecu and also see if it has a tip over switch.
SOURCE: is it Possible Tha Carburator Dirty Could cause The bike no Star
Yes, a dirty Carburetor can stop the engine from running.
Drain the carburetors. There should be a screw on the lower side of each CARB float bowl. Remove the screw then replace it after the fuel drains. Is there any water in the gas? 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). Turn the gas back on and wait a minute for the carbs to fill with gas. Try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.
FOR EACH CARB > 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.
FOR NO SPARK > Check the fuses. Next, check for spark but with a new spark plug. How good is the battery? Is the kill switch on? Does the side stand have a kill switch? Is it working properly? Tip-over kill switch on your bike? Check the operation of the ignition switch and all kill switches with a volt ohmmeter.
Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop.
Please rate this answer. Thanks

Hi and welcome to FixYa,
Initially, on a 'no spark' concern, check for the presence of IGN+12 on the red/white wire going to the ignitor unit. Additionally, check for the +12 on the red/black wires going to the ignition coils. When cranking check for pulsating voltage on the gray and red wires coming from the ignitor unit going to the ignition coils.
Postback results of initial voltage tests.
Good luck and thank you for asking FixYa.
