Here's my mods- stock motor,carbs,head,reeds- T5 pipes, k&n air filter with no snorkel, tors delete, running 280's and 27.5. Air screw out 1.5 turns. Living in western New York. It's seems a little rich, little boggy in the low end , air filter smells like gas, front of air box before filter seem a little wet but not soaking wet. Try 270's ?
