correct spark plugs

[cbn70]

Hi,

 

I have BR8ES plugs in the shee now. Talked to the dealer and said I should have B8ES plugs. Does that mean that I have resistor plug caps. If that is true, does it make a difference having a resistor plug as well as a resistor cap? ust need to get a bunch of plugs so I can do some plug chops to see how the jetting is. thanks

BR8ES or B8ES will work just fine. The lack of resistor can effect the radio reception in your car or your banshee! Lol! It can also effect a temperature gauge like the one CRJ Performance sells. I run BP8ES plugs and have for awhile. It showed to rev out better on the dyno with the BP plugs.

It can also affect the CDI with electrical interfearance.

 

My 97 banshee specifies B8ES Plugs. I belive the banshee's that have B8ES plugs still have a resistor, it is just in the spark plug caps vs being in the spark plug.

Dont you mean R?

 

 

I was just wondering because I have ran BP8ES and BPR8ES plugs. It is a projected tip spark plug that hangs down a little bit in to the combustion chamber.

I have ran both BR8ES and B8ES in all my two strokes and never had an issue. If you goto a Yamaha dealership, they will most likely sell you BR8ES'. At least thats what they sold me, I run BR7ES now for a little hotter spark.

7's dont give you a hotter spark. They temperatre of the spark plug runs hotter. A hotter running spark plug can cause pre ignition. You only want to run just hot enough plug to keep it from fouling. Running gasoline all that is needed is 8's. If your fouling plugs then you have a jetting problem not a plug heat range problem.

 

The only time you need to switch heat range of plugs with a banshee is running Methanol. You go 1 step colder to 9's.

Beat me to it ....

 

I run B9ES in my bike because I run a Nology Coil and wire setup.

The wires have resistors built in and Nology recommends non-resistor plugs with their hot wire setup.

I run a stock CDI and Stock Stator...too.

 

Unless you're running something fancy, BR or B8ES will work just fine...gapped at .028 to .030

looks like I will go with the B8ES. thanks for the help
