Will decel pop necessarily cause a DTC code? I just starting getting some pop on decel and sometimes between shifts. Only mod I have is the KW slip-ons which I've been running for about 1500 miles with no issues. I've tightened all exhaust fittings and there is no DTC indicated. Any chance bad gas could cause this? Bike has 3200 miles on it. Had a dyno done after installing Rush 2.0 earlier and the a/f ratios looked the same before & after install.
