br9ecs plug

[BANSH-alena-jol-EE]

i went to yamaha and said i wanted a highperformance spark plug, and they gave me a br9ecs, i think its titanium maybe, i donno, any opinions on this plug? bike has been working excellent, but ive heard that most ppl are using br8es, whats the difference?

Use the B8ES, the BR8ES is a resistor plug, unless your running an aftermarket coil/cdi or what not you don't need the resistor plugs. How much did you pay for this "High Performance Plug"? The 9s burn cooler than the 8s, if your running gas use the 8s. As for the br9ecs Ive never heard of them, maybe someone will chime in and tell you more about that specific plug. Hope this helps

good plug for alky-not gas

Ya I'm using b9es for alky, but the ecs series Ive never heard of?

[BANSH-alena-jol-EE]

perhaps i got the name of the plug wrong, i was in a rush just glanced , but i asked for more spark because i was getting an aftermarket cdi, amr stage 3 rev box, could have been a waste of money but its working well none the less. what is the adv/dis adv of the colder , warmer plugs?i paid about 10dollars for each

[AKheathen]

ecs is a gold palladium plug. i used the 10's once to fight glazing when i was adjusting my rotary valve in my sno-go @ 45degrees. i dropped back to 9's when the temp went back down, but it uses 9's normally, and always ride in freezing temps. as for the banshee, the 9's won't be able to stay hot enough to burn off deposits, and will foul if your jetting is right. as far as gold palladium goes, it's somewhere between platnum and irridium. i only noticed anything with denso irridiums, but that's because they work kind of like side gapping.

So what should i be using then? its hovering around -5 too + 5 day to day here in good old Newfoundland!

Who better to talk to about your jetting for cold, than "AKheathen"

you should run an 8. b8es, br8ecs, br8eya, any 8 plug baisically. i just used the different range plug to "cheat" while i was tuniing the plate out of normal elements. the right thing to do is to just jet it for colder temps. rule of thumb is 1 main jet size for every 25 degree drop, and 1 pilot for 50-70 degree drop, but you can fudge the pilot with airscrew and needle settings

 

 

oh, and if you think 10 dollars a piece is steep for a plug, try paying $29.00 a piece for denso irridium

why are the denso iradium so expensive?

[AKheathen]

for starters, only plug i know of that comes with a 5-7% hp gaurantee. the electrode is smaller than a .05 lead pencil. zero wear charictaristics. basically, you never have to buy another set. if you foul or even glaze, you can just torch them and put back in. trust me, i've done it. i havn't checked the price in a few years, but i'm gonna get some for the shee, since i've baught 3 sets of br8's and havn't gotten past the first set yet. i'll just use the other 2 for plug chopping.

I can go along with the reducing fouling from the reduced electrode diameter but I am having a hard time with the power improvement. The over all theory is smaller electrode, less voltage required to jump the gap and an increase in arc time. However, we have been able to duplicate the results with more voltage from the ignition. Timing will be affected either way and it is similar to increasing the spark advance slightly. maybe this is where they get the optimized 5-7% increase. on an OE motor with OE timing, it may show as such but we have not been able to prove drastic gains with performance plugs in high tune drag engines.

 

 

We do use them though on certain applications where ignition power is very limited. Generally they show the most improvement on the bottom end where ignition voltage on a constant loss ignition performs poorly.

yeah, IMO it's about the same as side gapping in regards to a more exposed spark path, but with the spark protruding further into the chamber. i saw no reduction in fouling, as that is solely a matter of tuning.

Total, 100% BS. Period.

 

In my world guys claw for every little bit of power, run exotic ignition, etc.

If there was a spark plug out there that could back up that claim, EVERYONE would use it.

 

I've tried everything from BRXES series (X being the heat range, gas or methanol) to NGK's EIX series (their irridium plugs) and the only thing that got faster was my wallet for being lighter than it already was.

 

Crap, pure crap.

 

Just to be clear.... the heat index number of a plug has nothing to do with how "hot" the spark is, it only means how much heat it holds in the engine.

ngk iridium is not the same as denso iridium
