My '01 YZ 426 has gone through nearly this entire year without skipping a beat. Several races, poker runs, fun rides with the family, etc. Normally starts on the first or second kick. Washed it last week after a ride, started it up, let it warm up, and put it away. Then tried to restart and it won't pop. It has done this on a couple of occasions, and I have had good luck simply replacing the plug, and it starts again. This plug is only about 2 weeks ( and 2 rides ) old, but it won't start. Yesterday cleaned out the carb (not like I found anything in it really) and cleaned up the contact points where the coil mounts to the frame, fresh gas, and still nothing. So the question is - Does this happen to anybody else? Is there a better plug to use? Once before I replaced the plug and it still wouldn't fire. Got another new one and - bam - started right up. Thanks guys.
