QUAD RAN GREAT IN PRACTICE THIS WEEKEND THEN TOOK A CRAP NOW IT WANT EVEN START OR EVEN AFTER STARTS WONT IDLE AND ADJUSTING CARB GETS NO REPONDS CLEANED CARB CHECKED FOR SPARK CHECKED REEDS ANT IDEAS GUYS IM THINKING COMPRESION OR STATOR THX IN ADVANCE

[Logan #34's Dad]

Sounds like a stator to me. They either work or they don't.

[drr5]

sounds like more than a stator , if its running that poorly could be many different things.

Is it getting fuel. These gas caps even aftermarket ones have been vapor locking.

Check to make sure the fuel is making it to carb.

[spider525]

getting fuel know that much. with stator even with getting stat it casn be stator ? how do you test stator?
:confused:

[durham454]

If it has spark and fuel, I'd be checking the silencer/spark arrestor and make sure it isn't plugged up, seen it before

The stator tests as follows:

1. YOU MUST USE A DIGITAL OHM METER!!!
2. On the stator the ohm reading between the red wire with white stripe (could also be white wire with red stripe) AND the Black wire with white stripe (could be white wire with black stripe) should be about 1284 ohms for the ETON style (3 bolt fan) stators and 689 ohms for the Kasea, LRX and DRR (4 bolt fan) stators.
3. The red wire with white stripe (could also be white wire with red stripe) to ground should be about 447 ohms for the ETON style (3 bolt fan) stators and 112.7 ohms for the Kasea, LRX and DRR (4 bolt fan) stators.
4. The Black wire with white stripe (could be white wire with black stripe) to ground should be about 837 ohms for the ETON style (3 bolt fan) stators and 576 ohms for the Kasea, LRX and DRR (4 bolt fan) stators.
5. From the plastic connector with the three wires, confirm that the black lead has 0 resistance between the lead and the frame of the atv. That is the ground lead. Any noted resistance in the ground system means the ground is BAD. We recommend always adding a wire between the engine and the frame for a better ground.

NOTE That the total ohms for #3 and #4 are the same as the ohms in #2. That is because we but the resistance of the two coils in series and added the ohms.

IF YOU DO NOT GET THESE READINGS your stator is BAD.

COILS:

1. There are two resistances in coils. Eton vs. Kasea.
2. The Eton should measure about 9.24k ohms checking between the high voltage lead (no boot) and the coil ground.
3. The Eton coil should also read about .5 ohms between the coil input and coil ground. Kasea reads about .3 ohms. Don't switch them because you can burn out your CDI and stator.

Your typical plug cap is a resistor cap and it should read about 5k ohms. A great replacement cap is the NGK TB05EMA.

If your stator, coil and engine kill wiring tests OK, you simply need a new CDI. I will not list out CDI test procedures since you have concluded your CDI is bad and because if you test the CDI improperly, you will damage the unit.
