I ride an 02 yz 426 with the stock suspension, never touched it. My riding ability has improved since I bought the bike and now the handles verry poorly. I am a 6' 1" 240 pound guy, and ride intermediate agressive. I have checked all of the sag measurements, 18mm static and 100 race. Do I need to go with heavier springs or should I start playing around with the settings. I am verry new at this suspension stuff.
