Hello! The standard plug for a 2002 KX100 is a NGK R6252K-105. This plug is designed with the center electrode and insulator tucked up inside the plug body and the side electrode attached to the rim almost flat. As a result, there is very little electrode projection down into the combustion chamber. I am finding that these plugs don't last very long and that engine performance falls off rapidly as a result. In fact, the engine won't even rev high enough to open the power valve. At $7 a pop, I think this is a lousy deal. I tried a BP7ES ( $1.50) that I use in my CR500 (after making sure the piston wouldn't hit the electrode). The bike runs great and pulls hard! Is it OK to run a BR6(7)ES or BPR6(7)ES without causing any damage? Thanks.
