Hi guys, New here...first post! Started riding a YZ 250 a few months ago, and loving it. Only thing I'm having concerns with, is keeping the throttle steady in variable terrain. While the YZ has great lugging power, it can also be very snappy. A friend suggested looking into flywheel weights. Have you experienced the difference? Is it worth it? Noticeable benefit? After riding a while, the arm pump is brutal. Thanks so much!
