Last night, I installed the big gun, trakside man! You wouldn't believe the moto skills I was showing! Anyway, I like the power, but I noticed my jetting wasn't totally crispy, because my buddy on his 250exc still smoked me on the track even after buying a big gun. Usually when I cant beat a KTM, my jetting isnt crisp? What do I do??? Jetting/Big Gun exhaust?
