I just recently did new jetting on the 400, it was all stock I did 160 main an I believe I did 42 pilot. Now it idles before it never idled an ran like crap. I cleaned the carb did all that fun stuff but now it back fires like crazy. I did a big gun slip on exhaust with a kn filter with no cover. Turned the idle screw 2 1/2 turns out ..
(It also doesn’t have a spark arrester in the exhaust) any ideas ?
