Question about Polaris ATV
Make sure the kill switch is in the run position.
AN engine need three things to run:
1*. Check the spark plug to make sure it is firing.. remove the spark plug.. make sure you have metal to metal contact and then turn the engine over.. (this might be a two man job).. the spark plug should have a nice big blue white spark,,(some electronic's will have a weak orange and still fire fine!)
2. Make sure you have gas in the tank and (going into the carb/FI)... (have to ask-actually have had 3 bikes in my career come in complaining -won't start...!! Add gas and they ran.. WOW!.. never charged any of them....the embarrassment on their face was payment enough!)
3*. While the spark plug is out... place your finger over the spark plug hole firmly .. keep the spark plug cap away from your hand..turn the engine over and see if it will blow your finger off..(it should blow it off the hole easily).
If any one of these three are not nearly perfect.. you have an issue!!
Check these and repost with the results...

SOURCE: My 2007 polaris 450 sportsman used to start with the pull start 2nd pull,now it starts for a couple seconds and stalls ,does this three or 4 x then starts and runs fine,by the way it won't start with
Could be time to replace battery, this is most likely the culprit. These fourwheelers are very picky when it comes to low power. Your starter is also most likely just fine, the clicking you hear is the solenoid on the starter, so your battery has some juice, but not enough amps to turn over the starter. Also If the fourwheeler has sat for a long time then you may just need to charge the battery. The 2007 is most likely fuel inject which uses even more fuel when running and it also has its own computer kind of like a PCM in a car or truck. These all need a good supply of power and the stator which is like an alternator usually needs the help of a fully charged battery to keep everything running properly. Also note, once you get a new battery or charge it in some cases the ATV should run smoother.

Lousy bulbs or poor voltage regulation (too high voltage will burn out incandescent lamps especially when you factor in all the bumps and vibrations ). Maybe you can special bulbs designed to withstand the conditions presented by your ATV.
