Hey . I got a 700 raptor 2014 with big gun pipe and k&n air filter. I am experiencing backfire on decel. I adjust my valve intake 0.13 mm exhaust 0.18mm and I put high temps silicone on all my joint of the exhaust. I still have backfire. I tried to adjust my yellow light on my ejk fuel controller. Still having backfire.
