I have a 1997 Suzuki Bandit and i have the stage 3 jet kit, Yoshimura RS-3 exhause, K&N Air Filters, and 5 deg, timing adv, now teh problem i am having is that when i start to slow down and drop gear i start to hear a popping sound come from my exhause nothing loud but it can be heard, also when first starting and its warm and i start to drive sometimes i hear something from the air filters like air suction or something in that area, what do yall think ?
