mrmatt Posted July 30, 2004 Report Share Posted July 30, 2004 Clymers says that that stock Banshee plug is a B8ES, but everytime I buy plugs from the Yamaha dealership they give me BR8ES. What does the R stand for? And should I even care? It seems to run the same with either type. Quote Link to comment Share on other sites More sharing options...
BdBanshee Posted July 30, 2004 Report Share Posted July 30, 2004 I always buy B8ES for mine, that's what it came with. The BR8ES is just a resistor plug. Quote Link to comment Share on other sites More sharing options...
nater006 Posted July 30, 2004 Report Share Posted July 30, 2004 Yup, what BD said.. its just a resistor, keeps it from being interfered with by RF devices. Quote Link to comment Share on other sites More sharing options...
Stuff Posted July 30, 2004 Report Share Posted July 30, 2004 I have run both and noticed no difference. While on the spark plug subject, where do you guys buy 'em and how much do you pay for 'em? I usually buy mine at the dealership for about $2.40 a plug but have been unable to get there because they now close earlier So, tonight I stopped by an Advanced Auto store and got 'em for $1.68 a plug Quote Link to comment Share on other sites More sharing options...
frocashmoney24 Posted July 30, 2004 Report Share Posted July 30, 2004 i get em from a local lawnmower shop for 250 a piece, no tax Quote Link to comment Share on other sites More sharing options...
nater006 Posted July 30, 2004 Report Share Posted July 30, 2004 Good ol NGK BR8ES.. and whatever the going rate at Murrays/Advance Auto is for 'em. Like $2 or so. Quote Link to comment Share on other sites More sharing options...
sredish Posted July 30, 2004 Report Share Posted July 30, 2004 Like they said, the R is for resistor. You don't need them as long as you have the stock plug wires, because the plug wires have resistors in the end. if, for some reason, you have different plug wires, or are unsure, then you should run the BR8ES.

frocashmoney24 Posted July 30, 2004 Report Share Posted July 30, 2004 yea, im runnin NGK plug wires so im good Quote Link to comment Share on other sites More sharing options...
racer Posted July 30, 2004 Report Share Posted July 30, 2004 ok, ive got factory wires and NGK caps. what should i be running? Quote Link to comment Share on other sites More sharing options...
red ore Posted July 30, 2004 Report Share Posted July 30, 2004 Run eiher. UNless your worried about them making static on your CB radio, or making it hard to hear the handle bar mounted Stereo, just get which ever cheeper, or easier to find. I get the b8es plugs for $1 each, and the br8es's are about $.40 more. Quote Link to comment Share on other sites More sharing options...
bansheeryder_69 Posted August 1, 2004 Report Share Posted August 1, 2004 What about br9es? I was told that they have a cooler spark and they keep your motor cooler but does that even matter and does it even help with performance, or does it take away power?

sredish Posted August 1, 2004 Report Share Posted August 1, 2004 What about br9es? I was told that they have a cooler spark and they keep your motor cooler but does that even matter and does it even help with performance, or does it take away power? that's complete bullshit. a cooler plug is not going to make your engine run cooler, in fact, that's so ridiculous i almost want to laugh. a plug's heat range has to match the heat of the combustion chamber. the "heat range" is actually the rating as to how fast the plug disperses heat. if it doesn't disperse heat quickly enough then it will melt, if it disperses heat too quickly, then it won't get hot enough to get an efficient spark. That's why you must match the heat range of the plug to the heat of the chamber. the only way to know if your plug is the correct heat range is by looking at the ground strap at the tip of the plug. there is a slight color change that occurs on this strap. If the color changes near its end where it sits over the center electrode, then the spark plug heat range is too cold and what you're seeing is the color changing due to the heat transferring too quickly. If the color changes color near where it's welded to the base ring, then your spark plug is too hot and what you're seeing is a slower heat transfer from the ground strap to the base ring. Ideally, you want the ground strap to change color at about the half way point, about where it makes it's 'L' shaped bend. That would be the only reason to change heat ranges, do not change, unless your plug color shows it is necessary. Quote Link to comment Share on other sites More sharing options...
