I just re jetted my carb after putting on a white brothers slip-on. I followed the Dynojet specs for a aftermarket exhaust under 3000 ft in elevation. I live/ ride at sea level in Florida. This thing really cracks and pops when I'm on the track and come into corners letting off of the gas. What could my problem be? Still not jetted right? Fuel Screw (which I don't even know what it adjusts)? Hope you guys can shed some light for me.
