I have a 97 RMX 250. THe manual says to run a BR9EV. I know a lot of people run a BR8ES in their 2 strokes. Is one plug better then the other when riding in the dunes (Glamis)?

Your breakdown of the plug was correct along with the advice to keep the reccomended BR9EV plug. Changing plugs without a good knowledge is a recipe for disater especially with a 2 stroke. You could melt a hole in the top of the piston in less than a minute.
