Hey guys, just a tip. Today I swapped out the cheap stock plug for an NGK Iridium DPR8EIX-9.
Here's the link on Amazon:

Without making any other modifications or changing any settings I can report that as soon as I fired up the bike I immediately noticed a difference. The engine sounded better, and from the first time I rolled on the throttle I could feel a big difference in power delivery.
The throttle became much more responsive and it felt like there was more immediate torque.
I had my friend (a pro dirt bike rider) give it a whirl, and he reported feeling the same thing. Also, another friend said it sounded different. So I've got a high degree of confidence in suggesting that everyone spend the $9 and swap that stock plug ASAP.
