Correct plugs for the Banshee

[Steves banshee]

I went to a motorsports place and purchased spare plugs for the Banshee for when i go ride incase i have any problems. Anyways the guy looked it up and gave me NGK BR8ES but the Shee has BR9ES plugs in it. which do i run? Also what should the clip be set in the needle jet? I need to check that out to. Its seems to be strong as other Shee's i have rode before so i think its probably right but i want to know for sure. When i find my compression gauge i am gonna check the compression to make sure it is what the guy says it is, so i do run the right octane fule in it. Thanks :biggrin:

What should the gap be?

For gas run the BR8ES. You can get them for like 2 bucks each at pepboys, autozone, ect. dont get them at the dealership, they rip your shit off for them.

 

For the gap i want to say its like .023 but I could be wrong. depending on what mods you have is going to depend what jetting but you should be around the middle clip, 310 main, 27.5 pilot, air screw 2.5 turns for a bike with aftermarket pips and the airbox lid off. it might be a little off but it will get you very close.

BR8ES

BONE STOCK settings according to Yamaha are as follows:

 

Plugs:

Nippondenso: W24ES

 

NGK: B8ES (ive seen BR8ES, not sure what the diff is...)

 

B9ES likes to run a little hotter, if you can run them without fouling... go right ahead.

 

gap: .028 - .031

 

Main jet: #200

 

Jet needle clip position: 3 (middle)

 

Pilot air screw: 2 turns out

 

All this is a stock bike, below 5000 feet of altitude and above 32 degrees F outside...

 

colder out: higher main jet #, 220 (240 and 4th position on needle clip if below 14F degrees) and 1/2 less turn out on pilot air screw.

 

Higher altitude: 190 main jet, 3rd groove on clip and 2.5 turns out on pilot.

My 1987 Manual says B8ES, my 2001 manual says BR8ES.

I thought a NGK B9ES was colder than a NGK B8ES, and the only thing the R is for on some of those NGK's is to tell it's a resistor plug.

B9 is colder than B8. And, B7 is even hotter. The BR is a resistor plug.

Thanks for all your answers to my questions. I have to check where the guy has the needle clip at, i put the plugs they say are right which is the ones you guys say to. When i took the plugs out the color was a little fat not much, but on the right side or throttle side the plug was a little wet. i take it for a ride now and it wants to flip backwards just rolling out, not dumping clutch which i know they will, then mid range and higher it bogs down a little, it isnt as crisp as the first time you hit the throttle. i havent drove it much other then in my neighborhood, maybe i didnt let it warm up enough. I was gonna take it to trails, but i couldnt get my buddies trailer, mine was stolen during the winter. Gotta go buy one so i dont have to depend on other people. i could of thrown it in the back of my truck but my girlfriend wanted to ride her oddessy to and couldnt get em both in the back of my f-250 short bed even standing one up. I am trying to find my compression gauge so i can check compression to make sure i can run lower octane in it then what the guy said he ran. it has a K&N airfilter on it and its clean as new. I dont know if a reed is messed up or if the jetting or air fuel screw messed up i will have to check it compared to what you guys have on here. the guy i bought it from i dont think new much i think he bought it and freshend the motor and just up and sold it. i can tell the motor has been apart. like i said its strong from a low roll or holeshot and midrange its not clean. thanks for all your help. :biggrin:

I dont care what the manual says BR9EYA is the way to go especially if your running it on the trails
