Plug Type and Performance

[i12gofast]

I currently run BR8ES NGK's on a 01 shee with K&N filter, Boysen Power Reeds, reed spacers, boost bottle, Dyno Jet Stage 3 jet kit, Timing +4.......everythign else is is stock.

 

Would trying out any different model # plugs show any type of increase or decrease in respect to performance? From what I though, the different plug part # had somethinig to do with the heat...but im not exactly sure what.

 

Any help appreciated.

 

Thanks fellas.

well heres one i know.

The BR8ES is standard.

The BR9ES will be colder

The BR7ES is hotter

Use the plug that goes with the normal operation of your shee. using incorrect heat ranges can cause plugs to foul over heating and piston damage.

Use a high heat plug for low speeds and low temps.

And a cold plug for high speeds temp and engine loads.The plug should be hot enough to burn off deposits fuel etc. but not to hot where it may burn holes or predetinate.

now that was a cut and paste if i ever seen one

I'm running the NGK BR8EIX. It has the finer iridium tip. $8 ea. It seems to start cold better and possibly a little better performance. I ran 17 gallons of fuel through the shee in 3 days in the OR dunes last weekend and from the looks of the plugs after the long weekend, strap and electrode show zero wear, they will probably last forever. It also seamed like when I took the bike out on the sand for the first time on that trip, 50 degrees, 100% humidity, getting rained on like a mofo all night long on the trailor, after a 2 minute idle warm up, and previously being started in the garage several times without riding it to clear it out, the bitch was ready to kill with the first twist of the throttle. It never once acted like it was cold or loaded up with fuel all 3 days.

 

I'd only recommend using NGK heat range "8", The performance benefits from the other style electrode tips is very slight other than longevity. Aftermarket ignition (dyna or GYTR cdi box) will give a stronger spark and noticeable power increase if thats what your looking for.

Okay on the same note, wont using a CDI box and a timing adavnce plate cause damage?

[sredish]

not directly. it's just that the box will advance the timing some and then if you advance it even more with the plate, you could be putting it into the risk zone. if you know how much the box is advancing and was sure not to push it, then no.

 

Regarding plugs. DO NOT change heat types unless your plug colors shows it's necessary. If you don't know where to look for that info on the plug, then you shouldn't be messing with different heat ranges. Stick with an "8" NGK plug and it'll be fine.

br8eix plugs .crisp instant response... no loading or long warm up times

NGK IRIDIUM ARE THE PLUG TO USE. TWO YEARS HARD WORK IN MY SHEE STILL LIKE NEW

I have always used the br8es in mine and would like to switch to the iridum plug. I have pipes, k&n, open air box, boost bottle. Should i stick with factory plugs or could i run the iridium plugs and be safe?

Yip, you'll be safe. ... BR8EIX for Iridium plugs. Dig deep in your wallet, they're not cheap!

 

I've got a pair to go in this w/e, but want to do some plug chops on the standard type plugs first.

i have been running iridium br8eix for about a year now with no problems till last week. my brother was using my bike for the first time (rookie) at Dumont Dunes last weekend and after an hour of rideing it turned of on him and would not start at all. the only way it would start was by pulling it and then you had to keep on reving it cause it would idle by itself. well when i came home put my old plugs and started right up.

 

what do you guys think happend and/or could of caused this?
