<!-- from fixya rte -->What to do when fourwheeler wonts start - ATVs

Trace the wires from the fan to the sensor.

Your starter is probably out, or not properly connected. Locate the starter and there should be two wires going to it, they both should be marked with + and - make sure red goes to positive and black to -
If you want to test your starter before buying a new one, take it off of the fourwheeler, and hook it up to the battery. (note: this is not recommended by the manufacturer may void warranty. If you do do it.... Hold on to that starter.)

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.

does it finally go in gear? if so sounds like shift solenoid going bad

I suggest you purchase a manual if you are mechanically inclined.

loose wiring someplace prolly ign switch ( key). start back up ok ? something loose !!! reason !!!

First you should wash it clearly and dry it in hot air then rub it by a dry clean cotton

its not a washer its a mountingplate

check the main fuse

1 thin wire in, one big fat wire to the spark plug. its not rocket science.
