Take your breather cover off and see if that affects it if you went to a larger jet size you may not be getting enough air to comply with the extra fuel you're dumping in i would suggest drilling a few holes in the breather lid if it straightens up when you remove the lid. i ran into the same problem when i rejetted an artic cat 400

Backfire


Yes, it could (and probably is) be an air leak. Check to be sure the carb is tight in the intake manifold, and make sure the hot-start isn't loose and is sealing properly. Also make sure all of the exhaust system joints are tight, an air leak in the exhaust will make a four-stroke pop and backfire like an old work truck with no muffler...
