Spark plugs

Get rid of it- yes i have heard of it but it is not a resistor--your machine is not running properly i would reccommend a
BR8EIX that is the best plug you could run its iridium---but one the other hand if you don't want to spen the money buy a BR8EG thats nickle or BR8EV thats gold The finer the electrode the better your off ---- helps with throttle response and is good for lugging the motor--- I'm running a BR8EVX ---If you want to go back to A stock plug it is a BR8ES --- sTICK TO A RESISTOR PLUG IF YOU DON'T IT MAY MESS UP YOUR CDI---HAPPY TRAILS
