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)?

stick with the reccomended plug. a br8 is hotter than your br9 and could seize the bike. if you get a plug that has a resistor (R), the correct leanth (B), the correct heat range (9), and 14mm threads (e), you will be fine. br9es should work. someone correct me if im wrong about which letter ches to what thing. it doesnt really matter here though, as long as it has a BR9E in it, its fine. BTW, anyone know what the "S" means in br9es
