So it took me too long to figure out that my 86 savage backfires because she was jetted to run a little too lean to meet emission standards, and one know what size I should go to? Stock exhaust and everything still

I've tried everything else, maybe somebody swapped my carb with a '95 or later carb, could you humor me and tell me what size jets I should have?

wow ,people really know stuff here .please help me to , if you would , I put dual pipes on my 650 sav, now it may need rejet , should I get just a jet or two to try ,or get a stage 1or 2 jet kit .i have a 96 650 savage .thanks
