I have noticed a number of questions lately regarding spark plugs, different codes on the plugs mean different things.
Here is a nice chart which decodes the codes !
So if we take the standard blaster plug which is B8ES, we can interpret it as : B = Thread Diameter : 14mm; 8 = Heat Range: Medium; E= Thread Reach: 19mm; S= Firing End Construction: Standard super copper core center electrode.
If you have a BR8ES, the R = Construction features: Resistor type, and unless you have a radio that you dont want to cause interference with, the R is not necessary on a bike
Some guys use the B8EG, and G = Firing End Construction: Fine wire nickel center electrode.
