32:1...and I run a BR9EG, but I also hear you can run a BR9ES and its cheaper because it doenst have that radio frequency stuff (don't know exactly what that is) in it, and im told you dont need that anyway.
B"R"9es is a resistor plug, has the radio 'stuff' in it. The difference in price is because of the metal used in the electrode. Non-resitor plugs have been known to interfere with ignitions on bigger bikes. Stick with the R type plugs.
