Hi, Fathead79 if your bike has been idle for months or years and does not want to start you will have to deal with a few remedies:
1. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
2. Remove your air cleaner and clean and re-oil per Mfg. specifications.
3. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
4. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
5. Replace spark plug with a new one and check for spark.

SOURCE: aprilia rs 125 won't start!!

right you done quite a bit, so whats left, fuel seems ok .. so ht lead ht cap, spark plugs dont always come with right gap, any leaks with airflow either side of carb, remember the filter often acts as a restrictor too. try the putting a small amount of fuel in cyclinder after cleaning plug, should atleast get a backfire, is choke setup ok, carb mix if not factory sealed is generally 1 and 3/4 turns out from tight,

My d100 will not start


Check for good , strong spark. Take spark plug out and ground the outer core of the plug to the engine. Hold the plug with a pair of insulated pliers. Have someone crank the engine while you observe for a good strong blue spark. If the spark looks nice and bluish, then next would be to clean the carburetor. I suggest trying a "quick clean before taking the carburetor bowl off. Take spray carburetor cleaner and spray inside the carb throat with the air cleaner off. Also take about 1/2 can/bottle of fuel line injection cleaner and put it in the gas tank. Then try starting the mower. May sure the gas in the tank is fresh.

Cranks but will not start


Spray some starting fluid in the airbox inlet while cranking the engine with the throttle open. If it starts for a few seconds, your problem is with the fuel. If it does not fire still, You need to check for spark at the spark plugs

Makita dcs340 will not start, spark plug is sparking but when placed back into the cylinder it does not fire.


Spray some starting fluid in the carb because it may not be getting fuel. If it fires the fuel may be bad. If the fuel is more than 2 months old dump it out and put in fresh fuel.

Hi, I have a 1988 BMW K100RT. It's been sitting in the shed unstarted for 12 months. Today I dumped the old fuel and put half a tank of fresh fuel in, installed a brand new battery, oil filter and engine...


Removing all the old fuel is a good start, the tank is only one point, you also need to flush the old fuel out of the total system including the fuel rail and pipes, to ensure fresh fuel is first into the engine.

Engines need 4 things: Spark, compression, fuel, exhaust

1) Does spark plug have spark?
Take out plug, put plug wire back on plug, hold plug threads against metal part of engine, pull cord, do you see spark between plug and engine?

2) While spark plug is out, put finger over hole and pull cord. Do you feel suction that shows compression?

3) What about the exhaust port? Is the screen blocked with carbon deposits and dirt? Soak it in WD-40.

4) Do you have 2-cycle oil in gasoline? Do you have fresh gas? Did you leave gasoline in tank for several months? Is the carburetor clogged with gum?

5) What about the air filter? Does it fire up without air filter? Will it fire if you spray WD-40 into carburetor? Can you keep it going while spraying WD-40 into carburetor?
If it fires with WD-40 but won't keep going on it's own, then the gas is not getting to carburetor or carburetor is clogged with gum.

ok a couple of things to try 1 try using starter fluid in carburetor 2 second spritz and crank does it fire or pop? if yes then there is spark, if not then pull spark plug and put new one and try again, if no then leave spark plug out of engine and lay on engine with wire connected and look for spark( do in shade to see better. if no spark then coil if bad. if it does fire on starter fluid, check gas filter and air cleaner it may be too lean or rich to fire properly.

I'd start with one of these and move on to the next.

Fuel
Spark.

Is it getting fuel? You should have an "in tank" electric fuel pump. When you turn the key halfway (just before turning the engine/starter over), you should hear the fuel pump prime. Easy way to check is to look in the throttle body while someone turns the key to the "on" position. You should see/smell the fuel. You can also listen to the gas tank while the key gets turned. You should hear the fuel pump run.

To check spark, pull a spark plug out, put it back on the plug wire and rest the electrode end of the plug up against the engine or exhaust manifold and have someone turn the engine over. You should see the spark plug firing. Don't hold the plug or wire while doing this. You'll get zapped if it's working ok.

If these both check out ok, then take a look at your firing order. If it's off by a significant amount, it may not fire. I've seen this happen when a cap/rotor/wires were changed and the wire/rotor was not positioned on the correct cylinder. (Most of the time they will at least fire or backfire, but either not stay running or run REALLY badly if the firing order is off.
