Correct spark plug for 85/86 250R?

[Anton]

Does anyone know the correct make and model of spark plug to use for my stock 1985 250R? I didn't see it on the specification pages of 3wheeler sites. I am told I'm runnning the wrong spark plug and should change it.

what are you running? most people run b8es (NGK) me(banshee) i run br8es(resistor)

i'm running a BR8EG same heat range just a little different material on the electrode,,,,,,,,

I am running an NGK but don't know which model. I was told to use a Champion spark plug... ?

Anyways I looked on the NGK website and they have the following listed for a 1985 250R:

Standard BR9ES
Fine Wire BR9EV
VX Platinum BR9EVX



what are you running? most people run b8es (NGK) me(banshee) i run br8es(resistor)

Is there an advantage to using a resistor plug on a 250R? The plugs listed on NGK's website are resistor plugs, but you say to use a B8ES? Also is there any advantage to using a hotter plug (8) instead of the cooler plug (9) that NGK lists on their website?

Do you run BR8ES on a 250R or Banshee?

kasey: Should I go with the BR8EG for my stock 85 250R motor? Or should I use a B8ES or BR8ES or the BR9ES as listed on the NGK site?


I will also be replacing my 1986 200X spark plug. The NGK site has the DR8ES-L listed, is this the one to go with?

The r just stands for resistor for radio interference. So when you are riding around the neighborhood people wont hear your engine running on there tv and radios.

And on my sleds i use to carry two sets of plugs with me depending on outside temp the br8es and the br9es. But sence i have switched to Champions n2c and thats all i run now. They work in all heat ranges with out fouling out.

And on the 200x i run the DR8ES-L and i replace it about once a year.

the eg plugs are more expensive than a regular plug , so i don't know if it is really nessesary in anything but a racing application,,,,, my local parts guy gave me these to try ,,,,

if you want to walk home buy the champion plug.

I've only ever had two bad plugs in my ATV's- one Champion and one Splitfire. These were defective not fouled. The Splitfire lasted two rides and cost seven dollars.

I use NGK BR8ES in my 85' 250R, my girlfriend has a Banshee and I use B8ES on that.
