My Cannibal came with a cr9ek but my manual says to use cr10ek. I noticed some people are running the cr8ek. Does this plug foul less often? also does it burn hotter? Does it burn a tank of feul faster?

 

I think most people have had better luck w/ the CR8EK, and yes it burns hotter.

 

Nitro,
The last plug I would run is the CR10EK, unless you really want to find out what hard starts and plug fouling is all about. My Speed came with the CR10EK in it and it seems to have been the cause of my hard starts and fouling. Once I put in the CR8EK, starts right away; barely even cranks...just fires on first push of the button. JIM

 

NGK-CR8EK

 

Dose anybody know if any plug companies make a platnum plug for ATV application? I would imagine that it would boost performance and down time.

 

Yes. NGK actually has a platinum equilevant to the EK plugs, but they run about 25 bucks each and don't prove themselves to many any better at not fouling than the conventional version when used on a single cylinder engine.

Honda's 500 Rubicon comes with this plug as standard equipment and yes, they do foul out.

The plugs such as Splitfire and Accel U-Groove have never really been shown to offer any horsepower increases either on a single cylinder engine. They do "somewhat" well in a sport bike with a 4 cylinder.

These references made about the CR8EK producing a hotter spark than the CR10EK is false. The only thing the 8EK does over the 10EK is that it disapates heat slower than the 10EK. Plug body temprature...not the flame temprature.

 

Thanks guys. Im new to the Dale so is there any special procedures i should be following or things not to do to keep the spark plug from fouling more often?

 

Yes, make sure you are using the correct starting procedure, this is very important and if not used, can cause your plug to foul. This info should be in your manual but here it is:
Make sure quad is in neutral and battery is fully charged.
Turn your key on, turn switch to on, hold in clutch and just bump the starter button. You will hear the fuel pump come on, wait about 5 seconds and now hit and hold the starter for no more than 3 seconds, if it does not start, wait another 5 seconds and try again but again, hold the starter in no more than 3 seconds. The key is when the quad is cold, to just bump the starter button and let the fuel pump pressurize.

 

Thanks Brian
