    battery is fully charged and turns the bike over just fine

    You might be right about the battery. Reason being is that I am in the process of selling this bike and everytime some comes over to look at it, it is started for short period of time and then turned off. This problem started shortly after that. I got frustrated trying to figure it out and let the bike sit for about week. Went out one day, replaced the plugs and it started up like a champ. The plugs probably didn't have anything to do with it. The battery proably had a chance to build itself back up. I just went out and put trickle on it and it definetely showed that the battery was not fully charged, it was reading 5 on a 10 amp trickle chaarger. Just might be the problem. Motorcycle batteries are so small and need the alternator to properly keep them up. What do you think?

1)First, try starting your motorcycle again, but this time pay careful attention to your starting procedure. Are you forgetting that the sidestand has to be up or that the motorcycle must be in neutral to start? Modern motorcycles are equipped with safety lockouts to prevent starting your bike in gear and riding away with the sidestand down. Starting routines become second nature and sometimes even these simple steps are overlooked.

2)Once you’ve checked the safety lockouts, determine if you are getting power to your starter. Turn your motorcycle on again and press the starter button. Does the starter turn? If yes, does it turn at its normal speed? A slow cranking starter means that the starter is getting power, just not enough to start your motorcycle. If all you get is a clicking noise, there isn’t enough power to activate the starter solenoid. Insure that your battery is fully charged and the cables are clean and tight. No matter how tempted, never jump start a motorcycle with a car! The excessive current can be devastating to a motorcycles’s sensitive electronics. For more information please see my article on motorcycle starting systems.

3)The next check should be fuel supply. Is there gas in the tank? I can’t count how many times I’ve “fixed” a motorcycle by filling the tank. Don’t just trust the gauge; check the level visually. For those of you with fuel petcocks make sure they are on. If your fuel petcocks are on reserve don’t assume that all of the fuel in the tank is usable. The bottom of the tank is where sediment and water collects. This often doesn’t cause a problem until the tank is almost empty.

4)If your starter turns normally and you have a full tank of gas your motorcycle should start, right? Not necessarily - so if your bike still doesn’t start, it might be time to call for a tow. Your motorcycle needs the fuel to enter the cylinders and be ignited by a spark at a precise instance for proper combustion. Components that might still be at fault are clogged carburetors or fuel injectors, an inoperable fuel pump, or ignition system. See “Advanced Diagnostics” to find out more...

2003 harley 1200 sportster won't start when warm tuns over no spark just changed coil no difference starts right away when cold

Hi Curtis, the CKP sensor needs compression to send correct signal to the ICM/ECM, make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Battery voltage below 8.7 volts, loose or broken battery cables especially ground cable to frame.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, MAP or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm.

2010 sportster 48edition,rear cylinder missfires at iddle with 1600 hydrocarbons reading and front at 200 hydrocarbons.Is the 1200cc sportster engine known to have this kind of problems?

No, Harley Sportster engine is the best engine Harley ever built in my opinion. If your engine is fuel injected, I'm afraid you'll have to take it to the dealer to find the problem. If it's carbureted, you may can fix it yourself if you can find the problem.

The engine needs three things to run, compression, fuel, and spark. Since it's a 2010 model, it's new and the compression should be good but just in case, a quick compression test should be done. Average compression should be about 120 pounds per square inch.

Next, you must have fuel. With a hydrocarbon reading of 1600, I'd suspect that your getting fuel to the cylinder. Matter of fact, it may be too rich. Check your intake manifold for vacuum leaks. If your bike is fuel injected, you'll have to take it back to the dealer for service. There is no way a carburetor can cause this, it's got to be a vacuum leak if it's too rich on one cylinder and correct on the other.

Finally, you need spark. I would guess this is your problem. If the fuel is not ignited, you get a "missfire". Try removing your spark plug wires and install another set of plugs in them. Leave your original spark plugs in the heads. Spin the engine with the starter and watch the spark. If the spark looks good, install the new set of plugs in your engine and try that. If not, you need to check the output of your coil.

1200cc 20000w reg one spark plug is wet the other is black and dry

That means your mixture is too rich. The cylinder with the wet plug may have a cracked rings as well, but i would rejet to a leaner mixture and see if that solves it. Your plugs SHOULD be dry and greyish/brownish
